Question Five
A 50mm diameter solid bar is drilled axially and concentrically to a depth of 90 mm with a
20mm diameter hole. The bar is then loaded by a torque, which produces a maximum shear
stress of 86 MN/m² in the bar. The total angle of twist is measured to be 0.65 degrees.
Determine
a) the applied torque
b) the total length of the bar
Take the Modulus of Rigidity as 75 GN/m?
