How Compound Machines Make Work Easier

What is a compound machine?

A) It is made up of more than one simple machine.

B) It has movement in only one direction.

C) It makes work more difficult.

D) It can only be acted on by one force.

Answer:

A) A compound machine is made up of more than one simple machine.

A compound machine is made up of two or more simple machines that work together to perform a task. They make work easier and more efficient. Compound machines utilize the advantages of each individual simple machine within them to accomplish a specific function. For example, a bicycle is a compound machine that consists of various simple machines like wheels, gears, and pedals working together to enable movement.

By combining multiple simple machines, compound machines leverage the unique abilities of each component to achieve a desired outcome that would be difficult to accomplish with a single simple machine. This synergy results in increased efficiency and effectiveness in performing tasks.
