Problem 160671
Consider the square shaft 6 metres long with each side being B cms.

The formula or shear stress due to torsion is
= T r / J (1)
where is the shear stress
T is the torque applied in Kg / cm2
. r is distance of the extreme point on the square shaft from the center of the shaft
J is the moment of inertia of the shaft
As the shaft is square in cross section the moment of inertia is
J = 1/12 ...
