Question

A solid circular torsional member OPQ is subjected to torsional moments as shown in the figure (not to scale). The yield shear strength of the constituent material is 160 MPa.
A solid circular torsional member OPQ with applied torsional moments at P and Q. Segment OP has a diameter of 0.1 m and length of 1 m. Segment PQ has a diameter of 0.08 m and length of 0.5 m. A torque of 2 kN.m is applied at P and 1 kN.m at Q.
The absolute maximum shear stress in the member (in MPa, round off to one decimal place) is ___________
