Equilibrium. We say an object is in ?equilibrium? if all the forces on it balance (add up to zero). Figure shows a beam weighing 124 N that is supported in equilibrium by a 100.0-N pull and a force F at the floor. The third force on the beam is the 124-N weight that acts vertically downward. (a) Use vector components to find the magnitude and direction of . (b) Check the reasonableness of your answer in part (a) by doing a graphical solution approximately to scale. Figure:

ANSWER:Solution to 75P Here there are three forces. Force along the floor, an upward pull of 100N, and a downward force 124N. We need to resolve the forces, Step 1 It is mentioned that all the forces are in equilibrium. Thus using equation of equilibrium of forces, In x axis, In y axis,
