A solid massless cylindrical member of 50 mm diameter is rigidly attached at one end, and is subjected to an axial force, P = 100 kN and torque T = 600 Nm at the other end as shown. Assume that the axis of the cylinder is normal to the support. considering distortion energy theory with allowable yield stress as 300 MPa. The factor of safety in the design is _____ (Round of one decimal place)
