Question

Check the accuracy of the relation C = (πηr²)/2L for couple per unit twist (C) of a wire of length (L), radius (r) and coefficient of rigidity(h).

Answer 1

Answer:

Badminton is a racquet sport played using racquets to hit a shuttlecock across a net. Although it may be played with larger teams, the most common forms of the game are "singles" and "doubles".

Answer 2

Torsional rigidity is the ratio of the shear stress to the angle of deformation of the cylinder and is given by $C=\dfrac{\pi \eta {{r}^{4}}}{2l}$
