A solid circular bar ABCD with fixed supports at ends A and D is acted upon by two equal and oppositely directed torques T0, as shown in the figure. The torques are applied at points B and C, each of which is located at distance x from one end of the bar. (The distance x may vary from zero to L/2.)
(a) For what distance x will the angle of twist at points B and C be a maximum?
(b) What is the corresponding angle of twist (max? (Use Eqs. 3-46a and b of Example 3-9 to obtain the reactive torques.)
