ANSWER:

Problem 5-123The shaft is used to transmit 30 hp while turning at 600 rpm. Determine the maximum shearstress in the shaft. The segments are connected together using a fillet weld having a radius of0.18 in. Step-by-step solution Step 1 of 3 Calculate angular velocity of the shaft. 2N = 60Here, N is the speed in rpmSubstitute 600 rpm for N. = 2 × 600 60 = 62.83 rad/sWrite the equation for power transmitted by the shaft. P = TSubstitute 62.83 rad/s for and 30 hp for P. 550 ft.lb/s30 hp x 1 hp = T x 62.83T = 30×550 62.83 = 262.613 lb.ft
