History of bikes
The document summarizes the history of bicycles and motorcycles from their earliest origins in the late 18th century to developments in the 20th century. Some of the key events and innovations discussed include the invention of the velocipede in 1817 which was one of the first two-wheeled riding machines, Kirkpatrick Macmillan's invention of the first pedal-driven bicycle in 1839, the introduction of the penny-farthing style bicycle in 1870, and the safer chain-driven safety bicycle design introduced in the 1880s which resembled modern bicycles. The document also notes how bicycles grew increasingly popular in the late 19th century as designs improved, leading to their mass production and social impacts including changes in women
The History Of Bicycles
The document summarizes the history of bicycles from their invention in 1817 to modern times. It describes the early walking machines and bone-shakers that led to the first true bicycles with large front wheels in the 1870s. Safety bicycles soon followed with same-sized wheels and chains and sprockets. The addition of the pneumatic tire invented by John Boyd Dunlop made bicycles vastly more comfortable and popular in the late 1800s. Bicycles became a widespread form of transportation and recreation through the early 20th century until declining in the postwar era but resurging with new styles like mountain bikes.

Electric-Bicycle-PPT.pptx
Electric bicycles, also known as e-bikes, are bicycles with integrated electric motors to assist with propulsion. There are a variety of e-bikes that range from those with small motors to assist pedaling to more powerful models similar to mopeds. E-bikes use rechargeable batteries and can travel up to 25-32 km/h, depending on local laws. E-bikes are classified based on whether the motor assists with pedaling or provides power on demand via a throttle. Pedal-assist e-bikes augment rider pedaling up to 25 km/h while e-bikes with higher speeds or more powerful motors may be classified as mopeds. E
Differentail
- The drive pinion drives the ring gear which is attached to the differential case. When going straight ahead, power is transferred equally to both wheels. When turning a corner, the wheels must travel at different speeds to prevent tire scrubbing, so the differential pinion gears "walk" around the slower side gear to cause the other side gear to turn faster.
- Limited-slip differentials limit the amount of differential action allowed compared to open differentials. They provide more driving force to the wheel with traction when one wheel begins to slip while still allowing wheels to turn at different speeds when cornering.
- In operation, driving torque is transmitted equally to each axle until traction is lost by one wheel. Then

Design and fabrication of dual chargeable bicycle
With the increase in fuel prices, pollution content in atmosphere and due to gradual end of the non renewable sources
of energy we have to alter the source of our energy in our vehicles. Considering all these reasons we have to switch
over to other sources of energy instead of using conventional sources such as petrol which in future will be going to
extinct. One way to alter the energy source is to go for electric vehicles or e bikes. Electric driven vehicles uses
battery as a source of energy which provide power to motor which in turn provide torque to wheels .The old design
of electric bicycle was having only a single mode of charging, it was just capable to travel 15 km through battery and
was not ergonomically good. The new design uses a low rpm alternator for charging the battery by keeping it in
contact with front wheel .A Motor of 0.5hp provides torque to the rear wheel and the gear ratio is kept 5:2 .battery
discharging time is approximately 2 hrs and charging time through alternator is 1 hour and the bicycle can attain a
maximum speed of 15 km/hr. This work is more beneficial in hilly region and confined areas like college campus
and schools, generating zero pollution, zero noise effect and no fuel consumption.
Design and fabrication of dual chargeable bicycle
This document describes the design and fabrication of an electric bicycle with a dual charging system. The new design uses a low rpm alternator connected to the front wheel to charge the battery while riding. A 0.5 hp motor powers the rear wheel through a 5:2 gear ratio. The battery can power the bike for 2 hours and be recharged through the alternator in 1 hour, allowing the bike to reach speeds of 15 km/hr. This dual charging system makes the electric bike more useful for transportation in hilly or campus areas by extending its range.
Mountain Biking
Mountain biking began in California in the 1970s when people started riding old "klunker" bikes off-road. Pioneers like Gary Fisher and Tom Ritchey helped develop the first true mountain bikes. In 1981, Mike Sinyard founded Specialized Bicycle and produced the first mass-produced mountain bike, the Stumpjumper. Mountain biking grew into a new sport and industry, spawning new bike technologies, races, and tourism opportunities around the world. It remains a popular way for people to get exercise and enjoy scenic outdoor locations.
An approach for experimental modification of the existing
The document proposes modifications to existing tricycles used by physically challenged people. The objectives are to reduce human effort, provide space for carrying goods, and improve comfort and maneuverability. The proposed design includes three wheels, two chains, four sprockets, a footrest, two hand paddles, and a metallic structure. Power would be transmitted to both front wheels instead of one rear wheel for easier steering. Additional features like a basket and water bottle holder are included. Comparisons are made between existing and proposed designs, and a future scope of adding a solar cell power source is discussed.
The downhill 123
The origins of mountain biking began in the late 1970s in California when groups of friends would have downhill races on motorcycles in the hills of Mount Tamalpais. These races were eventually banned due to environmental damage. However, the riders continued by using standard road bikes that they would carry up the hills on trucks. Gary Fisher was a pioneer who adapted his bike to allow him to pedal up the hills independently without polluting vehicles. This allowed riders to enjoy the sport in the hills of California in a more environmentally friendly way.

Suspentions p df
This document discusses motorcycle suspension systems. It describes that motorcycles use suspension to provide safety, comfort and handling by isolating riders from road bumps and vibrations. The most common front suspension is the telescopic fork, which acts like a hydraulic shock absorber. Rear suspension usually involves a swingarm and either twin shock absorbers or a mono shock absorber. While twin shocks provide more wheel travel, mono shocks now offer better performance, handling, stability and are easier to adjust. The document concludes that the project will use a telescopic fork for front suspension and a mono shock absorber for rear suspension.

IRJET- Retro Direction Bicycle
This document describes a retro-direction bicycle. Key points:
1. A retro-direction bicycle uses a gearing mechanism that provides a second gear ratio when pedaled backwards, allowing the rider to climb hills more easily.
2. The mechanism was developed in the early 20th century and uses a single chain running from the pedals to a rear sprocket with two freewheels, engaging different sprockets when pedaling forward or backward.
3. The document discusses the components of the bicycle like the shaft, sprockets, chain, and bearings. It also describes the working principle and benefits of the retro-direction design.
about bicycle onstruction and parts
Bicycle frames are designed with either a diamond frame or step-through frame. The diamond frame includes a top tube connecting the head tube to the seat tube. Historically women's frames had a lower standover height using a step-through design. Materials have progressed from steel alloys to lighter aluminum, carbon fiber, and titanium. Drivetrains use chains, with some using shaft drives, to transmit power from the pedals through multiple gear ratios in the rear cassette or hub to accommodate varied terrains and cycling needs.
Aysha
The document discusses the Suzuki Hayabusa motorcycle. It describes the Hayabusa as a sports motorcycle made by Suzuki since 1999 that holds the record for the fastest production motorcycle in the world, with a top speed of 188-194 mph. The name "Hayabusa" is Japanese for "Peregrine Falcon," a bird known for its speed. The original intent of the Hayabusa was to surpass the Honda Super Blackbird CBR1100XX as the fastest production bike. It succeeded in doing so, proving to be around 10 mph faster. This gave the Hayabusa the title of fastest standard production bike of the 20th century.

How to be a Super Champion
The document outlines the "5S of Super Champions" developed by Sijin Bt, the founder of the Sports & Management Research Institute. The 5S are presented as crucial factors that determine an athlete's career success and value: 1) Skill, 2) Style, 3) Score, 4) Stamina, and 5) Support. Following these 5S, such as acquiring the right skills and coaching, developing a personal brand, focusing on performance analytics, ensuring injury prevention, and obtaining support from agents, can help an ordinary athlete become a celebrated sports star and super champion.
SPEED (S)KILLS
The rising number of deaths and severe injuries due to illegal motorbike races and stunts is a social problem now. Banning superbikes will not prevent or reduce illegal bike racing and bike stunts. Youth will alter the bikes for more speed. It will cause more crimes and casualties. Illegal racing of autorickshaws with altered engines and carburettors is common in Chennai.
The project SPEED (S)KILLS initiated by the Sports & Management Research Institute (SMRI) based on the studies conducted by our experts suggests considering SPEED as a SKILL, not as a CRIME and to create adequate infrastructure and opportunities for our youth to exhibit their speed skills and to make living using their SPEED SKILLS. We can make it possible by constructing adequate motor racing tracks and by promoting motorsports. Many of the world's most famous motor racing events had their origins in illegal racing events. We request all good-hearted organizations and people to work with us to help the speed-loving youth of India to track their talents on the right track to prevent and reduce illegal motor racing and motor stunts.

This document discusses reasons why Indian footballers struggle to play full 90-minute football matches. It identifies key issues such as many players in India learning the game on dusty, hard surfaces instead of grass fields, which can cause lung problems and injuries. This means players have difficulty adapting to proper grass pitches. Additionally, many play on smaller-than-regulation pitches in India, so they are not used to running the long distances required in full international matches. Addressing issues like access to well-maintained grass fields and implementing standardized pitch sizes could help Indian players boost their endurance and competitive ability.

Game Plan to Win Football World Cup_Mal new.pdf
The book ‘GAME PLAN TO WIN FOOTBALL WORLD CUP’ reflects the dreams of millions of Indians who want to watch India wins the football world cup and suggests what India has to do to realize that dream. India has to change its mindset thinking about hosting or participating in the world cup and must start thinking about winning the world cup. We must prepare a game plan for winning the world cup by analysing our strengths and weaknesses.
This book lists the reasons for the inability of Indian footballers to play 90+ minutes in international match settings. During the formative years and most of their lifetime, Indian footballers are playing on the ‘wrong fields’ such as bare hard grounds and small grounds instead of FIFA-specified football fields. It leads to issues such as reduced lung functioning, ligament issues and difficulty to play in wings and playing long passes. The majority of Indian footballers do not get adequate nutritional, psychological and player-specific fitness training support during their formative years and career, due to the ignorance of parents and coaches. It affects their overall performance and reduces their career span. India must have maximum FIFA standard playgrounds to give our footballers maximum opportunity to practice and play to global football standards.
Many great football talents miss the chance of playing for better clubs due to the ‘one-day selection trials’ of our academies and clubs.
The flaws of the Indian football ecosystem are the major factor which prevents India from developing as a football superpower naturally. India doesn’t have many professional football clubs and doesn’t have an ideal football league system. Governments and football governing bodies must foster a football ecosystem which supports the formation and growth of professional football clubs and a series of interconnected league football leagues at different levels with promotion and relegation. India must encourage community football clubs at the grassroots (villages) level and fans-owned cooperative clubs at the taluk level as sports start-ups. Governments should give the facility management responsibility of the existing stadiums and playgrounds owned by the government, departments, local self-governments and education institutions to the cooperative football clubs and community football clubs under revenue-sharing conditions.
Governments should not pamper the football ecosystem through financial aid to associations, clubs and tournaments etc. Governments should provide only repayable grants to football governing bodies based on the performance outcomes. Government should make football associations accountable and responsible for taking state-level and national-level football ecosystems to European standards by empowering football clubs, leagues and sports facilities managed by the clubs self-reliant and financially viable.

Dynamic League Point System
Recently, our students have developed a new pointing system named Dynamic League Point System (DLPS) for sports leagues (home & away format), which is more advanced than the present 3-point system developed by Jimmy Hill.
One of the most significant aspects of the DLPS is that it rewards the away win and away draw by awarding bonus points (4 points for away win and 2 points for away draw) and it punishes the home match loss with a negative point (-1 point for a home loss and 1 point for a draw). The DLPS will ensure cut-throat competition in every match.

Indian Premier League (IPL) ---2024.pptx
The Indian Premier League (IPL) is one of the most prominent and lucrative Twenty20 (T20) cricket leagues in the world. Since its inception in 2008, the IPL has revolutionized the landscape of cricket by blending sports, entertainment, and commerce. This summary provides an overview of the IPL's history, structure, notable performances, controversies, and its impact on cricket and beyond.
History and Formation
The IPL was launched by the Board of Control for Cricket in India (BCCI) in 2008, inspired by the success of domestic T20 leagues like the English T20 Cup and the now-defunct Indian Cricket League (ICL). Lalit Modi, the then Vice-President of BCCI, played a crucial role in conceptualizing and launching the league. The inaugural season kicked off in April 2008 with eight franchises representing different cities in India.
Structure and Format
The IPL follows a franchise-based model, where teams are owned by a mix of corporations, Bollywood stars, and other high-profile individuals. The league originally started with eight teams, although the number has fluctuated over the years due to various reasons including expansions and terminations. As of the latest seasons, the IPL features ten teams.
The tournament format includes a double round-robin stage, where each team plays the others twice, followed by playoffs. The top four teams from the round-robin stage qualify for the playoffs, which consist of two qualifiers, an eliminator, and the final. This format ensures a highly competitive and engaging tournament, culminating in a grand finale to crown the champion.
Teams and Their Evolution
The founding teams of the IPL were:
Chennai Super Kings (CSK)
Delhi Daredevils (now Delhi Capitals)
Kings XI Punjab (now Punjab Kings)
Kolkata Knight Riders (KKR)
Mumbai Indians (MI)
Rajasthan Royals (RR)
Royal Challengers Bangalore (RCB)
Deccan Chargers (now defunct, replaced by Sunrisers Hyderabad)
Over the years, the league has seen new teams such as Pune Warriors India, Kochi Tuskers Kerala, Gujarat Lions, and Rising Pune Supergiant. The most recent additions are the Gujarat Titans and Lucknow Super Giants, introduced in the 2022 season.
Iconic Players and Performances
The IPL has attracted the best talent from around the world, with numerous iconic players making significant contributions. Some of the standout performers include:
Sachin Tendulkar (MI): The "Little Master" brought his legendary status to the IPL, winning the Orange Cap (top run-scorer) in 2010.
Chris Gayle (RCB, KXIP): Known for his explosive batting, Gayle holds the record for the highest individual score in an IPL match (175*).
MS Dhoni (CSK): Dhoni's leadership has been instrumental in CSK's success, leading them to multiple titles.
AB de Villiers (RCB): Renowned for his innovative stroke play, de Villiers has been a consistent match-winner.
Virat Kohli (RCB): The highest run-scorer in IPL history, Kohli's batting prowess is unmatched.
