! Figure P.11.14 shows a thin-walled cantilever box-beam having a constant width of 50 mm and a
depth which decreases linearly from 200 mm at the built-in end to 150 mm at the free end. If the
beam is subjected to a torque of 1 kNm at its free end, plot the angle of twist of the beam at
500 mm intervals along its length and determine the maximum shear stress in the beam section.
Take G= 25 000 N/mm².
Ans. Tmax = 33.3 N/mm².
