Compute the ratio of the torque, Mechanical Engineering

Compute the ratio of the torque:

Compute the ratio of the torque transmitted by a hollow & a solid shaft of the similar material, length & weight.


di = internal diameter of hollow shaft

 d0 = external diameter of hollow shaft

d = diameter of solid shaft

Similar material means modulus of rigidity and density is similar. The weight being equal means the cross-sectional areas of solid & hollow shafts are similar:

∴  n = di / do

d = do

For same material τs = τh

 ∴         Ts    /(1 - n2 ) (3/2)   =Th/(1 - n4 )2
