Stress: When any object of certain material is subjected to tensile or compressive or shear force, there may be a chance that its dimension will be affected. If the dimension of a material is changed due to application of forces we can say that the material is under stress or experiencing the state of stress. Stress is defined as the Force per unit cross section area. Stress = F/A Stress is

Connecting rod big-end bearings are precision-insert bearings. The insert-type bearing is usually not adjustable. However, it can be replaced, if the rod, crankpin, and other engine components are in good condition. When a rod bearing falls, an analysis should be made to determine the cause. Then the cause can be eliminated so that the failure will not repeated. Lets move into the failure

The purpose of this article is to create a list of mechanical engineering books for the core courses of Mechanical Engineering. There are a number of books available for the meticulous study of Mechanical Engineering subjects. If we were able to study all the books of ME core courses then it would have been great ! But sadly it is not possible. And most of the times it is not possible to buy all

Heat treatment of metal is a term used to describe an operation or a series of operations which involves heating and cooling of a metal or an alloy when it is in the solid state for obtaining some desirable properties (without changing the chemical composition ). The main objective of Heat Treatment of Steel 1. Enhancing the hardness of the steel. 2. Stress reliving from the metal after hot

Bernoulli's Equation states that - For an incompressible liquid (density constant) which is flowing in a continuous stream; the total energy remains the same for all the particles, when the particle is moving from one point to another point. Mathematical expression of Bernoulli's equation: P1/w + (v2 )1/2g + z1 = P2/w +( v2)2 /2g + z1 = constant Here P1 , P2 = Pressure at points 1

Stress-strain are very important terms of solid mechanics. Strength of materials is a branch of engineering which deals with the material's properties to resist its failure. This topic also discusses about the behavior of materials under different level of forces. What is stress and strain In this topic we will discuss the definition of stress and strain, their formula as well as relationship

A design engineer must have a good concept about the mechanical properties of materials. Different manufacturing processes and heat treatment can change the properties of materials. A good design engineer should have a good knowledge about these properties. Engineering materials are divided in the following divisions - 1. Metal and Metal Alloys . Example : Iron, Copper, Nickel etc. 2. Non-
