In this modern age of competition, manufacturing sector is no exemption. With increasing
customer demands the precision and accuracy required in the manufacturing of component is very high. In
order to have mass production and high productivity of any component the availability of an SPM
(Special Purpose Machine) is a must. The hose-clamp finds various applications in moderate pressure
devices like the automotive pipes, LPG pipes etc. This paper deals with bringing in simple but effective
machine to roll the hose clamp into its circular form and to enhance the quality and quantity of
production.
Keywords — SPM, Hose-Clamp, Productivity.
This is a short description and some problems for the design of clutches.This also include the various classification in clutch and its description,use and also advantages of using these kinds of clutches.
It also includes a short view through different types of numerical problems which are solved for practising.

Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

4. Analyse a mechanical system by breaking it
into input-process-output
• A pair of pruning scissors is a mechanism that will need to work
according to a specific system if it has to produce maximum MA.
• The system diagram for cutting process will look like:
INPUT
Force movement
Force on handles. As
far back as possible
PROCESS
Mechanism
Pruning scissors
Fulcrum in the middle
where the two levers
pivot(moves around a
point)
OUTPUT
Desired force/movement
LOAD: where the cutting
has to take place
5. System diagram for a gear system
with a MA of 4:1
INPUT
Force movement
Force on driven gear with
60 teeth.(driven gear)
PROCESS
Gear mechanism
Gear system MA 4:1
Fulcrum in the middle
where the gears pivot
MOVES AROUND AN AXLE
OUTPUT
Desired force/movement
LOAD: driver gear with 15
teeth. (driver gear)
6. Formula for calculating MA
•Use the following formula to workout how to get
a 4:1 gear ratio
•Gear ratio=Number of teeth of driven gear
Number of teeth of the driver gear
7. System diagram for a gear train with the
driven gear rotating faster than the driver
•If a Driver gear=40 teeth is driving a
driven gear=20 teeth the gear chain will
speed up i.e. for every turn of the driver
of the driver gear, the driven gear will
turn twice.
8. System diagram for gear train
INPUT
Force movement
Force on driven gear 20 teeth.
(Driven gear)
PROCESS
Gear mechanism
Gear system MA 1:2
FULCRUM in the middle around
an axle
MOVES AROUND AN AXLE
OUTPUT
Desired force/movement
LOAD: Driver gear with 40
teeth. (Driver gear)
9. Test corrections
• Question 1
1. Human arm=third class lever, office punch= second class lever,
bottle opener= first class lever
2. The office punch
3. A second class lever is when the load lies in between the fulcrum
point and the effort.
4. >1
5. Effort= handles, fulcrum= the middle where the two levers pivot,
load= blades where the cutting take place
10. Test corrections cont’d
Question 2
1. Spur gears
2. Idler gear
3. Idler gear-is used so that the rotation of the two gears is the same
4. Gear train- is usually made up of two or more gears
5. Bevel gear
6. Gear- a wheel with teeth
