In Case Of Bending Of A Rod, Only Young’s Modulus Comes Into Play And Not Modulus Of Rigidity, Even Though There Is Change In Shape – Explain.
—
by
When bending is produced in a rod, some filaments of the rod are extended, some are contracted, and the others remain unchanged. So longitudinal stresses are developed in the rod due to the elastic reaction against extension and contraction of the filaments. As a result of the presence of the longitudinal stress and strain, Young’s…
