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) Responses
A. 309 N
B. 936 N
C. 104 N
D. 208 N
To find the force saved by using the lever, we need to calculate the force exerted when using the lever and then subtract it from the force required to directly lift the crate.
The force exerted when using the lever can be found by dividing the force required to directly lift the crate by the mechanical advantage of the lever: 312 N / 3 = 104 N.
To find the force saved, we subtract the force exerted when using the lever from the force required to directly lift the crate: 312 N - 104 N = 208 N.
Therefore, Joaquin saves 208 newtons of force by using the lever.
The correct answer is D. 208 N.
