‘The shaft consists of three concentric tubes, each
made from the same material and having the inner and
outer radii shown. If a torque of T = 800 N- mis applied to
the rigid disk fixed to its end, determine the maximum shear
stress in the shaft.

It is made of A-36 steel (G = 11000 ksi) and
consists of a solid inner shaft CB which is
surrounded by and attached to a tube 4B using a
rigid ring at B. The ring at A can also be assumed
