According to Varignon’s theorem, the algebraic sum of several concurrent forces about any point is equal to the moments of the moments of their resultant about ..
The sliding of a solid body in contact with another solid body is always opposed by force of friction. Friction acts in the direction opposite to that of relative ..
Coefficient of Friction The coefficient of friction (μ), is a measure of the amount of friction existing between two surfaces. A low value of the coefficient ..
Hooke’s Law According to Hooke’s law for a small deformation, the stress in a body is proportional to the corresponding strain.” i.e., stress ∝ ..
According to the principle of superposition of forces, when a Hookean body (An elastic body or material for which Hooke’s law equation can be assumed is said ..
Engineering mechanics is the study of forces that act on bodies and the resultant motion that those bodies experience. Engineering mechanics subject involves ..
A force exerted on a body can cause a change in either the shape or the motion of the body. The unit of force in SI system is the newton (N) and CGS system is dyne. ..
Different types of loads in engineering mechanics are compression, tension, torsion and bending. Compression: Compression loading is an effect in which the component ..
The moment produced by two equal, opposite and noncollinear forces is called couple. Couples have certain unique properties and important applications in mechanics. ..
Lagrange-d’Alembert principle is generally known as D’Alembert’s principle, stated by French physicist and mathematician polymath Jean le Rond ..
To fully understand the safety of a machine, all forces that act on the links need to be examined. It is widely accepted that the best way to track these ..
The problems of mechanics can be solved by Newton’s laws of motion. The three laws proposed by Sir Isaac Newton, described as follows. Newton’s First ..
Mechanical properties helps us to measure how materials behave under a load. Mechanical properties of materials are mentioned below. Elastic Material: A material ..
Slenderness ratio is the ratio of the effective length of a column (Le) and the least radius of gyration (r) about the axis under consideration. It is given by ..
