Three forces on the cart (figure 2) gravity or weight of the cart W1 = Mg, working vertically downwards the normal force N, vertically upwards and the tension force T acting through the rope along the positive x-axis, as shown above. Pulleys with grooved rims are called sheaves. A flexible belt connects the two pulleys The width of the pulleys changes depending on how much power the vehicle needs. In belt drive, pulleys are affixed to shafts at their axes, and power is transmitted between the shafts by means of endless belts running over the pulleys. Everything you need in one place: Free Mechanical Aptitude sample questions, practice tests, and tips - updated for 2022. Because the pulley/sheave rotates, the rope moves 2x farther than the load but requires 2x less force to move. For example, say we want to lift a 100-lb. To prevent the flat belt from jumping off the pulley, the cross-section of the pulley has a slight convex crown. The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw. IMA (Ideal Mechanical Advantage) = R/r. This pulley system provides a 4:1 mechanical advantage.
