Chapter 9, Problem 114P

Block A rests on top of block B and the cord is parallel to the inclined, if u=0.14 for all surfaces of contact. Determine the angle theta in degree when motion of B will impend block A weights 730N and B weights 1670N.

Determine the resultant of the line load acting on the beam ABC. 1200 lb/ft y 1700 lb/ft C 6 ft 8 ft

The L-shaped rod AOCD has an 80 kg mass hanging from it at B. The rod is leaning against a smooth wall at A. Point B is half way up OA. There is a journal bearing at C and a thrust bearing at D. They are properly aligned. A force F is pulling in the x-direction at B. Just as the rod comes off of the wall at A, what is the magnitude of the force F. 1 m B F 1m

6. Outriggers A and B are used to stabilize the crane from overturning when lifting large loads. If the load to be lifted is 2800 kg, determine the maximum boom angle 8 so that the crane does not overturn. The crane has a mass of 4700 kg and the center of mass is located at Gc, whereas the boom has a mass of 600 kg and center of mass at GB. 4.5 m GB 5 m 0.7 m GG -2.3 m B 2.8 m
