A 1.50-in.-diameter brass [G = 5800 ksi] rod is used as a shaft. Determine the thickness of hollow steel [G = 11200 ksi] tubing that must be bonded to the outside of the brass rod in order to increase the torsional strength 40 percent. Assume that the maximum allowable shear stresses for the brass and steel are 7200 psi and 9600 psi, respectively.
