To directly lift a crate 0.6 meters, Joaquin would need to apply 312 newtons of force. Instead, he uses a lever with a mechanical advantage of 3 to lift the crate. How much force does he save by using the lever?(1 point)

To find the force Joaquin saves by using the lever, we can use the formula for mechanical advantage:
Mechanical Advantage = Output Force / Input Force
Since we know the mechanical advantage is 3, and the output force is the force needed to lift the crate (312 N), we can rearrange the formula to solve for the input force:
Input Force = Output Force / Mechanical Advantage
Input Force = 312 N / 3
Input Force = 104 N
Therefore, Joaquin saves 208 N of force by using the lever.
