A single movable pulley is able to move over the rope through the groove. Its axis of rotation is not fixed. One end of the rope is fixed and effort is applied to the other end of the rope. The load that is to be moved is hung on a hook of the pulley. It is used to move...
A pulley is a type of simple machine which has a wheel on an axle designed to support movement, change the direction of the cable, and transfer power between the cable and the shaft. There are three types of pulleys - fixed, movable and compound pulleys. A fixed pulley is a...
it is attached to a fixed point and allows the rope or cable to do work. A movable pulley travels along with the object being moved by the pulley. A movable pulley multiplies the force being applied to move the object. Combining several pulleys can form a compound machine called a block ...
Attach the fixed pulley to the overhead anchor point, as described in Steps 1 to 3 above. Then, attach the movable bottom pulley directly to the load. Make sure both anchor points are sturdy enough to support to load that will be placed on them. When pulley systems fail, it is almost ...
