In the figure, a climber with a weight of 390 N is held by a belay rope connected to her climbing harness and belay device; the force of the rope on her has a line of action through her center of mass. The indicated angles are 0 = 45° and p = 30°. If her feet are on the verge of sliding on the vertical wall, what is the coefficient of static friction between her climbing shoes and the wall? %3D %3D Hs =Number i U

The uniform cylindrical drum weighs 250 lbs and is supported by a frictionless roller at A and the frame at C. The coefficients of friction between the frame and the drum at C are as follows, static coefficient u: = 0.3 and kinetic coefficient uk = 0.25. If the drum is at rest, find M required to start the drum moving? For full credit show a labeled free-body diagram. 2' 30°

Make it simple as possible. final answer must be correct.

problem number 6

As shown in the figure, the coefficient of static friction for both wedge surfaces is 0.4 and that between the 30-kg concrete block and the 20° incline is 0.70. Determine the minimum value of the force P required to begin moving the block down the incline. Neglect the weight of the wedge. Note: please show step by step working out. Also double check final answer please. As this is a dynamic question. Please use sine rule to solve this. Thanks
