7. A ladder of length 12 m leaning up against a wall makes a 50 degree angle with the ground. The top of the ladder has sliders so that it can slide up and down the wall. Therefore, consider the top of the ladder to be frictionless. The ladder has a weight of 189 N that acts at its center. Someone weighing Fg = 1000 N is 0.92 m vertically below B, but on the ladder. Another person is on the ground holding the ladder by pushing on it horizontally with a force F. If the coefficient of static friction is 0.32, find the horizontal force F that must be applied at a vertical height of 1.2 m to prevent the ladder from slipping. LL F 1.2 m 12 m 50⁰ Fg B .92 m
While digging a small hole prior to planting a tree, a homeowner encounters rocks. If he exerts a horizontal 199-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 23-kg prybar. 199 N 1260 mm 21 190 mm Answers: (a) Including weight, Fc = i N (a) Excluding weight, Fc = i N
