A construction crew must use a lever to lift a boulder. The mechanical advantage of the lever is 6 and the lever applies a force of 1600 N to the rock. What is the force that the construction crew must apply to the lever?

Answer 1

To determine the force that the construction crew must apply to the lever, we need to use the formula for mechanical advantage:

Mechanical Advantage = Output force / Input force

Given that the mechanical advantage is 6 and the lever applies a force of 1600 N to the rock (which is the output force), we can rearrange the formula to solve for the input force:

Input force = Output force / Mechanical Advantage
= 1600 N / 6

Input force = 266.67 N

Therefore, the construction crew must apply a force of approximately 266.67 N to the lever.
