The hollow circular shaft shown has a length $$\mathrm{L}=2\mathrm{m}$$. It is made of a material that has a bilinear stress-strain relation as shown. A torque is applied causing an angle of twist $$?=0.15$$ rad between the two ends of the shaft. - Draw the strain distribution and the shearing stress distribution along the radial direction of the section. - Determine the magnitude of the applied torque. - Determine the residual stresses at the outer edge and at the inner point of the section after the torque is removed.
