Compound pulley systems have both fixed and moveable pulleys, making the load feel a little lighter and enabling you to change the direction of the force. These systems are good for very heavy loads, even though, sometimes, you need more motion for the work to be done properly. Also called...

The systems are structures similar to circle rotating for work to be performed. The force gets transferred from axle to wheel. It is the ratio of radius to the axle to the radius of the wheel. The mechanical advantage is given by:
The firsttoolsmade of stone represented prehistoric man’s attempts to direct his own physical strength under the control ofhuman intelligence. Thousands of years were undoubtedly required for the development of simple mechanical devices and machines such as the wheel, the lever, and the pulley, by...
The Great Pyramid at Giza, built about 2500 bce, before the Egyptians knew the pulley or had wheeled vehicles, covers 13 acres (5.3 hectares) and contains the staggering total of 2,300,000 colossal blocks of granite and limestone weighing an average of 5,000 pounds (2,300 kilograms) each...
