4. A garage door (8 ft by 10 ft) weighs 200-lbs is pulled with a constant 25-lb horizontal force to open it as shown. Assume the door rollers (A & B) are frictionless and the door does not rotate or lift off rollers A & B. G is the center of mass of the door. Determine: a. Reactions forces at each roller support (A & B) b. The constant acceleration of the door. c. The time for the door to move 10 feet. Assume it starts from rest. Draw FBD and write governing equations. Show all work. 8 ft 1 ft 5 ft 4 ft -8 ft 10 ft B 3 ft 25 lbs
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
