They are permitted to use a non-programmable calculator but no other electronic devices.

D alemberts principle

D'Alembert's Principle states that the resultant of all external forces and inertia forces acting on a body is zero for the body to be in dynamic equilibrium. Inertia forces are represented as minus mass times acceleration. The principle allows equations of static equilibrium to be applied to bodies undergoing translational motion by considering an imaginary inertia force equal and opposite to actual inertia. Several example problems are provided applying the principle to analyze motion of connected bodies over pulleys, motion on inclined planes, and motion within elevators.

Turning Effect of Forces

1. The document discusses moments, which describe the turning effect of forces. A moment is calculated by multiplying the force by the perpendicular distance from the pivot.
2. It provides examples of calculating moments and using the principle of moments, which states that for an object in equilibrium, the sum of clockwise moments equals the sum of anticlockwise moments.
3. Determining the center of mass of an object allows it to be balanced on a pivot. The center of mass can be found experimentally by balancing irregular objects on different points and identifying where the lines intersect.

5. friction

Friction is a force that opposes motion between two surfaces in contact. There are two types of friction: static friction and kinetic friction. Static friction has a greater maximum force than kinetic friction. The laws of friction state that frictional force is proportional to the normal force and depends on the coefficient of friction, which varies based on the materials in contact. Problems involving blocks on inclined planes can be solved using the static friction force and applying equations of equilibrium. Wedges can be used to move heavy objects by applying a smaller input force, with the mechanical advantage determined by the wedge angle.

- Newton's second law is extended to rotational motion, defining moment of inertia and relating torque to angular acceleration.
- Several example problems demonstrate calculating torque, center of gravity, and rotational motion and equilibrium for various objects.

Unit ii equilibrium of rigid bodies

1. A free body diagram shows the forces and moments acting on an isolated body. A force couple system can replace a single force with an equal force and couple at another point.
2. A couple is a pair of two equal and unlike parallel forces that tends to rotate a body. Varignon's theorem states the sum of the moments of all forces about a point equals the moment of their resultant about that point.
3. Supports include roller, hinged, and fixed. Equations of equilibrium in 2D are the sum of horizontal forces equals zero, the sum of vertical forces equals zero, and the sum of moments equals zero.

Applications of artificial Intelligence in Mechanical Engineering.pdf

Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdf

Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

Accident detection system project report.pdf

The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.
