Chapter 3, Problem 3.3.15P
A hollow steel shaft used in a construction auger has an outer diameter d2= 6.0 in. and inner diameter d1= 4.5 in. (see figure). The steel has a shear modulus of elasticity G = 11.0 × 106 psi.
For an applied torque of 150 kip-in., determine the following quantities:
- shear stress
at the outer surface of the shaft,
at the inner surface, and
(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.
