A 1.1-in-diameter solid round bar has a groove 0.1-in deep with a 0.1-in radius machined into it. The bar is made of AISI 1020 CD steel and is subjected to a purely reversing torque of 1400 lbf·in. What are the values of the alternating and mean components of the shear stress? The value of the alternating component is kpsi. The value of the mean component is kpsi.
