Question

A metal cylinder of radius 5 cm has length of 20 cm . it is fixed at one end. If its twisted through 5 degree the torsion produced will be ?​


The solution : torsion produced =( r ) (theta) / l

= 2.5 degree



I want to know that how the calculation did here !!

Answer 1

The solution : torsion produced =( r ) ( theta) /|=2.5 degree
