1 in y -10 in +5 -5 in x = A cylindrical bar with 1-in diameter fits tightly in a circular hole in a 5-in thick plate. The shear modulus of the material is G 5.6E6 psi. A 12,000-in-lb axial torque is applied at the left end of the bar. The distributed torque exerted on the bar by the plate is given by the equation (x\ 1/2] C = Co - in-lb/in, where co is a constant and x is the axial position in inches measured from the left side of the plate. Determine the constant co and the magnitude of the maximum shear stress in the bar at x = = 2 in.
