Question

Two rotating rods in the vertical plane are connected by a slider block Pof negligible mass. The rod attached at A has a weight of 3 ib and a length of 8 in. Rod BP weighs 3.4 lb and is 10 In. long and the friction between block Pand AE is negligible. The motion of the system is controlled by a couple M applied to rod BP. Know that rod BPhas a constant angular velocity of 20 rad's clockwise. о А B 30° P Determine the couple M. [You must provide an answer before moving on to the next part.) The couple MIS lb ft

What are the components of the exerted on AE by block P?

Answer 1

Given : at A IAE Two rotating rods in the vertical plane are Conected by a slider block p of neglizible moss. The rod attached nes c weight, WAE = 316 and length 8in Rod BP weight, Wop - 3.4 lb length, friction between between block p and AE is neglizible. The motion of the system is controlled by a couple m corols BP has a constant on guler velocity W Bp = IBP = 10 in to sod BP. applied Because here rod BP 361 B w is constant hence m angular acceleration (2) Edw at Sop casso Hence her torque WBP in that Play rod ip zero Thet=0 m WBP IBP cos zo -O 2 M = WBP IBP Cos30 3.4 x 10 X COJ3 0 2 2 m ₂ 14.723 eb-in Component of the exerted on AE by blocks is zero in the given configuration because slider p is friction less MAE=0
