Definitions

• Simple machine—A machine that makes work easier by multiplying a force or changing the direction of a force

• Effort– work put into a machine also know as work in or win

• Load—work done by the machine, also know as work out or wout

• Mechanical Advantage (MA)—Force out/force in• Efficiency=(Work out/work in) * 100%

Simple machines

• Simple machines do a lot of things, but one thing they never do is multiply work. Why is that?

• A compound machine occurs when you put more than one simple machine together.
