Chapter 3, Problem 67P

3-67. Three 10-lb balls and one 15-lb ball are suspended from the pulley-and-cable system. If the pulleys are frictionless and the centers of all of them lie in the same horizontal plane, determine the sag s for equilibrium of the system. 10 lb 20 in. 20 in. 10 lb 15 lb 20 in. 10 lb

The skid-steer loader has a mass of 1.18 Mg, and in the position shown. The center of mass is at G1. There is a 300-kg stone in the bucket, with center of mass at G2. There is a similar linkage on each side of the loader.   - Determine the magnitude of the reaction of the pair of wheels B on the ground. - Determine the magnitude of the reaction of the pair of wheels A on the ground. - Determine the magnitude of the force in the hydraulic cylinder CD. - Determine the magnitude of the force the force exerted on ED at the pin E.

Consider the following system in static equilibrium. Force vector Facts at a distance from the pin support at point O. Draw appropriate FBD as necessary. Assume frictionless pulleys If the reaction forces at O is zero and magnitude F is 169N, a. Find F and "a". (F need not necessarily be in the 4 quadrant as shown below) b.
