Question

find the expression for twisting couple required to twist a uniform cylinder fixed at one end define torsional rigididty​

Answer 1

Answer:

this is your answer bro

Explanation:

Torsional rigidity is the ratio of the shear stress to the angle of deformation of the cylinder and is given by $C=\dfrac{\pi \eta {{r}^{4}}}{2l}$, where $\eta $ is the coefficient of rigidity, r is the radius of the cylinder and l is the length of the cylinder. This is for a solid cylinder.
