Saint-Venant’s principle states that if the forces acting on a small portion of an elastic body are replaced by a statically equivalent system of forces on the same ..
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 ∝ ..
Reynolds number (Re) is an experimental number used to predict the flow velocity in fluid flow at which turbulence will occur. It is a non-dimensional velocity ..
Pascal’s law states that A small force (F1) is applied to piston with a small area (A1) produces a much large force F2 on the larger piston. It is schematically ..
A simple pendulum consists of a concentrated mass known as the ‘bob’, which is free to swing from side to side at the end of a light cord or rod. When bob is ..
In physics, energy is defined as a property of objects which can be transferred from one object to another objects or converted into different forms of energy. Energy ..
Kepler discovered three empirical laws that accurately described the motions of the planets. The three laws of Kepler may be stated as, Kepler’s First Law: ..
Law of conservation of energy does not distinguish between useful and wasted energy. The law neglects ‘losses’ from the closed system into the environment. ..
Comparison of solids, liquids and gases (fluids) can be done in aspects like macroscopic description, mobility of molecules, density, molecular spacing, effect ..
Newton along with his three laws of motion, Newton published the law of gravitation in 1687. According to Sir Isaac Newton, Thus, the magnitude of the gravitational ..
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 ..
