Chapter 15, Supplemental Question 152 A 2.5-in.-diameter solid aluminum post is subjected to a horizontal force of Px = 8.8 kips, a vertical force of Py = 19.3 kips, and a concentrated torque of T = 4.2 kip-ft, acting in the directions shown. Assume L = 3 in. The yield strength of the aluminum is 49 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.
