The shaft is subjected to a distributed torque along its length of t = (10x 2 )

Question:

The shaft is subjected to a distributed torque along its length of t = (10x²) N ˆ™ m/m, where x is in meters. If the maximum stress in the shaft is to remain constant at 80 MPa, determine the required variation of the radius c of the shaft for 0 ‰¤ x ‰¤ 3 m.

= (10x²) N-m/m 3.
