Question

4-9. The dimensions of a jib crane are given in the figure.
If the crane has a mass of 800 kg and a center of mass at G,
and the maximum rated force at its end is F - 15 kN,
determine the reactions at its bearings. The bearing at A is a
journal bearing and supports only a horizontal force,
whereas the bearing at B is a thrust bearing that supports
both horizontal and vertical components.

R8-7. The uniform 50-lb beam is supported by the rope that is attached to the end of the beam, wraps over the rough peg, and is then connected to the 100-lb block. If the coefficient of static friction between the beam and the block, and between the rope and the peg, is us = 0.4, determine the maximum distance that the block can be placed from A and still remain in equilibrium. Assume the block will not tip. 1 1 ft 10 ft- Prob. R8-7 المسوحة فولا CamSearer

A tower crane (Figure 1) must always be carefully balanced so that there is no net torque tending to tip it. A particular crane at a building site is about to lift a m = 2700-kg air-conditioning unit. The crane's dimensions are shown in (Figure 2). The crane's counterweight has a mass of M = 10000 kg . Ignore the mass of the beam. Where must the crane's counterweight be placed when the load is lifted from the ground? (The counterweight is usually moved automatically via sensors and motors to precisely compensate for the load.)Express your answer to two significant figures and include the appropriate units. Determine the maximum load that can be lifted with this counterweight when it is placed at its full extent.Express your answer to two significant figures and include the appropriate units.
