Front

What is effort (input) force?

Back

the force one exerts on a machine

Front

What is the equation for ideal mechanical advantage (IMA)?

Back

IMA=effort distance divided resistance distance

Front

What is the equation for actual mechanical advantage (AMA)?

Back

AMA=resistance force divided by effort force
