how can you calculate the mechanical advantage a simple machine provides? (1 point)
simple machines do not provide a mechanical advantage.
divide the output force by the input force
divide the output displacement by the input displacement
divide the output force by the output displacement

Explanation:

Mechanical advantage (MA) of a simple machine is calculated by the formula \(MA=\frac{F_{output}}{F_{input}}\), where \(F_{output}\) is the output force and \(F_{input}\) is the input force. Simple machines do provide mechanical advantage. The formula for mechanical advantage does not involve displacements (\(\frac{\text{output displacement}}{\text{input displacement}}\) is related to velocity ratio in some cases but not mechanical advantage here) and \(\frac{\text{output force}}{\text{output displacement}}\) is not the formula for mechanical advantage.

Answer:

divide the output force by the input force
