Total load would be carried by the both sides of the block.
So shear force on one side of the block is 15000/2 = 7500 lbs.
That should be equal to shear stress * area of the one face of the block
So that
7500 = 90 * 6 * L
L = 7,500/(90*6) = 13.89 inch
Minimum length required( L ) is 14 inch.
Add Answer to:

G is 11.2*10^6 psi
A shaft of length 2 m has the hollow cross section shown below (distances of the centerline of the wall shown). The shaft is made of an A36 structural steel; see table in the back of the book for the material properties (and note that modulus of rigidity refers also to the shear modulus G). If a torque T = 10 kN m is applied at one end while the other end is fixed, determine: 1)...
