percy pulls on a rope that is held up by a pulley, like the one shown. the pulley is near the ceiling, and the other end of the rope is attached to a crate. percy applies 75 n of force to the rope, and the rope lifts the crate by applying a force of 75 n. what is the mechanical advantage of the machine? 0 1 150 5625
Answer
Explanation:
Step1: Recall mechanical - advantage formula
The formula for mechanical advantage (MA) of a machine is $MA=\frac{F_{out}}{F_{in}}$, where $F_{out}$ is the output force and $F_{in}$ is the input force.
Step2: Identify input and output forces
Given that $F_{in} = 75\ N$ (the force Percy applies to the rope) and $F_{out}=75\ N$ (the force the rope applies to lift the crate).
Step3: Calculate mechanical advantage
Substitute the values into the formula: $MA=\frac{75}{75}=1$.
