Please Help thank you

A 2.2-in.-diameter solid aluminum post is subjected to a horizontal force of Px = 8.9 kips, a vertical force of Py = 23.9 kips, and a
concentrated torque of T = 3.8 kip-ft, acting in the directions shown. Assume L = 3.5 in. The yield strength of the aluminum is
Oy = 70 ksi, and a minimum factor of safety of FSmin = 1.67 is required by specification. Consider points H and K, and determine
whether the aluminum post satisfies the specifications according to:
(a) the maximum-shear-stress theory.
(b) the maximum-distortion-energy theory.
