A hollow steel shaft used in a construction auger has outer diameter d2 = 6.0 in. and inner diameter d1 = 4.5 in. (see figure). The steel has shear modulus of elasticity G = 11.0 ( 106 psi.
For an applied torque of 150 k-in., determine the following quantities:

(c) Rate of twist ( (degrees per unit of length).
Also, draw a diagram showing how the shear stresses vary in magnitude along a radial line in the cross section.
