4.33 A force P of magnitude 90 lb is applied to member ACDE that is supported by a frictionless pin at D and by the cable ABE. Since the cable passes over a small pulley at B, the tension may be assumed to be the same in portions AB and BE ofthe cable. For the case when a = 3 in., determine (a) the tension in the cable, (b) the reaction at D 12 in. Fig. P4.33
Three bars are connected with frictionless pins to form the frame shown. The frame is loaded with a force of P = 670 lb. The dimensions on th figure are a = 7 ft, b = 5.1 ft, C = 5.1 ft, d= 7 it, and e = 9.5 ft. Determine the magnitude of: (a) The resultant force in pin B. (b) The horizontal and vertical components of force in pin D. (c) The horizontal and vertical components of force...
A 1-lb all is attached to a 30” long cord as shown. The
horizontal cord and ball are released from rest. When the cord
reaches a vertical position, the ball strikes a 5-lb steel block
initially at rest on a frictionless surface. If the coefficient of
restitution between the ball and the block is 0.9, what is the
speed of the ball before and after impact? What is the speed of the
block just after impact?
