What is Newton’s third law of Motion? The Third Law of Motion states, “If an object A exerts a force on object B, then object B must exert a force of equal…
Newton’s Second Law of Motion Notes pdf ppt
Newton’s Second Law of Motion: The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the…
Newton’s First Law of Motion Notes pdf ppt
Newton’s First Law of Motion: Newton’s first law of motion is often stated as An object at rest stays at rest and an object in motion stays in motion with…
Newton’s Laws of Motion Notes pdf ppt
Newton’s Laws of Motion: Sir Isaac Newton’s three laws of motion describe the motion of massive bodies and how they interact. While Newton’s laws may seem obvious to us today,…
Area and Mass Moment of Inertia: Notes pdf ppt Engineering Mechanics
Area Moment of Inertia: The second moment of the area around a given axis is called the area moment of inertia Now, for the above figure we have the axis…
Difference Between Moment of Inertia and Polar Moment of Inertia: Notes pdf ppt Engineering Mechanics
Main Difference – Moment of Inertia vs. Polar Moment of Inertia: Moment of inertia (which refers to the mass second moment of inertia) and polar (second) moment of inertia are both quantities which describe an…
What is Polar Moment of Inertia: Notes pdf ppt Engineering Mechanics
Moment of Inertia Definition: The concept of moment of inertia was introduced by Leonhard Euler. The resistance that is shown by the object to change its rotation is called moment…
