While digging a small hole prior to planting a tree, a homeowner encounters rocks. If he exerts a horizontal 242-N force on the prybar as shown, what is the horizontal force exerted on rock C? Note that a small ledge on rock C supports a vertical force reaction there. Neglect friction at B. Complete solutions (a) including and (b) excluding the weight of the 17-kg prybar. 242 N A, 1750 mm 15 B 220 mm Answers: (a) Including weight, Fc = i N (a) Excluding weight, Fc = i N

Solve for the required value of the force P to raise the load if (a) the coefficient of static friction between the wedge and the ground is 0.20 in the absence of the rollers, and (b) the rollers exist as can be seen in the picture
A mountain camper has problems with his off road vehicle. To hold it in place the camper wraps a rope abound a treen + turns. The coefficient of friction between the rope and the tree is u. = 0.23. The car pulls on its end of the rope with a force of 2250 N. The camper wants to pull on the rope with a force no greater than P = 54 N. P Determine the integer value of n. (Enter the minimum possible integer value of n.)
