Problem # p016


The steel shaft shown is mounted solidly at the wall at point A while at point C a torque T = 1.2 Nm is applied. For the given diameters and lengths
  • what is the angle of twist between point A and C ?

  • what is the value of the maximum (overall) shearstress ?

Modulus of rigidity is G = 75 GPa (steel) for both sections of the shaft.

d1 = 1.0 cm
d2 = 1.2 cm
L1 = 50 cm
L2 = 70 cm
