WebSelecting the + y -direction to be parallel to F → S, the first equilibrium condition for the stick is − w 1 − w 2 − w + F S − w 3 = 0. Substituting the forces, the first equilibrium condition becomes − m 1 g − m 2 g − m g + F S − m 3 g = 0. 12.18 We solve these equations simultaneously for the unknown values m 3 and F S.

WebTo solve this problem, we need to use the equations of motion and the concept of static friction. Since the golf cart is not moving, the net force acting on it must be zero. Therefore, the force of gravity acting downwards must be balanced by the normal force (perpendicular to the surface of the hill) and the friction force (parallel to the ... WebStatic friction is the force holding an object in place on an incline, such as the cheese in Figure 1. The friction force points against the direction that the object would slide without friction. Static friction keeps gravity from pulling the cheese down the incline.
