Compound machines

Scissors are compound machines because they contain both a wedge and a lever. A simple machine is a device or mechanism that changes force. Levers are simple machines that output force from a pivoting point.

Teams will complete a written test on simple and compound machine concepts and construct a lever-based measuring device prior to the tournament to determine the ratio between two masses. Most of the machines in the world are compound machines. A compound machine is two or more simple machines working together.

Whereas a simple machine does not always increase the mechanical advantage, a compound machine can. With a compound machine , a smaller amount of force can be used to move objects. Compound machines are combinations of simple machines. A machine is a tool used to make work easier.

Simple machines are simple tools used to make work easier. In science, work is defined as a force acting on an object to move it across a distance. Pushing, pulling, and lifting are common forms of work.

They perform more work and therefore offer a greater advantage than simple machines alone. A really good compound sewing machine is the Husqvarna Diamond sewing machine.
