Question

part e
mechanical advantage is the ratio of output force to input force. does the tool or device have a mechanical advantage that is greater than 1, equal to 1, or less than 1? do some research on the internet or at a library if you arent sure.

Explanation:

Step1: Recall mechanical - advantage concept

Mechanical advantage (MA) = $\frac{F_{output}}{F_{input}}$.

Step2: Analyze cases

If $F_{output}>F_{input}$, then MA > 1. This means the tool or device multiplies the input force. If $F_{output}=F_{input}$, then MA = 1. If $F_{output}

Answer:

If the tool or device multiplies the input force, the mechanical advantage is greater than 1. If it just transmits the force without any multiplication or reduction, the mechanical advantage is equal to 1. If it requires more input force than the output force, the mechanical advantage is less than 1.
