A bucket with mass m 2 and a block with mass m 1 are hung on a pulley system. A classic example of this mechanism can be witnessed over wells where the pulley and rope are used for lifting water-filled buckets. Attach the rope first to the bottom of the upper fixed pulley, then loop the rope down through the wheel on the moveable lower pulley. You will make samples of simple machines and calculate the mechanical advantage of a simple machine that you test. Because of the overrunning clutch, the servo motor only transmits torque to the pulley. Consider a pulley attached to a weight being lifted. The necessary parts and components for the CVT have been determined and considering the necessary constraints, its mechanism and components have been designed. 08 for dual drive systems with rubber-lagged drive pulleys, an automatic take-up, and 420° of wrap angle, or as large as 1. 2 Belt-Driven Pulleys Direction of Rotation and Speed The direction of motion of the pulley systems depends on the way the belt is fixed in the system.
