A solid steel bar of circular cross-section has diameter d = 2.5 in., L = 60 in., and shear modulus of elasticity G =11.5 X10⁶ psi. The bar is subjected to torques T = 300 lb-ft at the ends. Calculate the angle of twist between the ends. What is the maximum shear stress and the shear stress at a distance rA =1.0 in. measured from the center of the bar?
