The complexity can range from being very simple to very complex. . Domestic . Machines. A . common example of a domestic compound machine is nail clippers. A nail clipper contains two levers. A second class lever and a third class lever. The cutting blades themselves are also simple machines as they are inclined planes. . Definition. A chain drives works very similar to a belt drive system. It works by mechanically transferring power from once source (known as the driver) to another source (known as the driven). This is achieved from sprockets rather than sheaves pulleys (used in a belt drive). © 2012 Project Lead The Way, Inc.. Principles of Engineering. Gears, Pulleys, & Sprockets.
