Question

The solid circular drill rod AB is made of a steel that is assumed to be elastoplastic with τ_Y = 22 ksi and G = 11.2 × 10⁶ psi. Knowing that a torque T = 72 kip·in. is applied to the rod and then removed, determine the maximum residual shearing stress in the rod.

The maximum residual shearing stress in the rod is ksi.

The solid circular drill rod AB is made of a steel that is assumed to be elastoplastic with Ty= 22 ksi and G=
11.2 x 106 psi. Knowing that a torque T = 72 kip-in. is applied to the rod and then removed, determine the
maximum residual shearing stress in the rod.
35 ft
1.2 in.
The maximum residual shearing stress in the rod is
ksi.

Expert Solution

Step 1

Given,

Yield shear stress, $τ_{y}$ = 22 ksi

Modulus of rigidity, G = 11.2 x 10⁶ psi

Torque, T = 72 kip-in or 72000 lb-in
