Young’s Modulus and it’s applications with Example

Young’s Modulus Young’s modulus, also known as the elastic modulus, is a measure of the stiffness of a material. It quantifies the relationship between stress (force per unit area) and strain (proportional deformation) in a material undergoing tension or compression. The modulus is named after Thomas Young, a 19th-century British...


Strength of Materials MCQs Practice Set

1.Whenever some external system of forces acts on a body, it undergoes some deformation. As the body undergoes some deformation, it sets up some resistance to the deformation. This resistance per unit area to deformation, is called strain stress (correct) pressure modulus of elasticity 2.The deformation per unit length is...


Various types of Supports provided on the beam

Types of Supports in Structural Engineering:- 1. Roller Support: This type of support is mainly used for steel trusses of the bridges, which have one of their end supported on rollers. These rollers allows the movement of the beams towards left or right on account of expansion or contraction, due...


Shape factor and Poisson’s ratio in SOM

Shape factor is the ratio of a plastic moment(Mp) to elastic moment(Me) OR we can say that it is the ratio of plastic section modulus(Zp) to elastic section modulus(Ze). Shape factor shows the extra strength or moment possessed by a section, that is the strength or moment beyond yield point....
