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 out how much force Joaquin saves by using the lever, we need to calculate the force he exerts with the lever and then subtract it from the original force of 312 newtons.
The lever has a mechanical advantage of 3, which means that the force applied with the lever is multiplied by 3.
So, the force Joaquin exerts with the lever is 312 newtons / 3 = 104 newtons.
To find out how much force he saves, we subtract the force he exerts with the lever from the original force: 312 newtons - 104 newtons = 208 newtons.
Therefore, Joaquin saves 208 N of force by using the lever.
