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 th rock. What is the force that the construction crew must apply to the lever? A. 380 j B. 267 j C. 134 j D. 534 j
The mechanical advantage of a lever is the ratio of the output force to the input force. In this case, the mechanical advantage is given as 6.
Let "F" be the force that the construction crew must apply to the lever.
According to the definition of mechanical advantage:
Mechanical Advantage = Output Force / Input Force
6 = 1600 N / F
Rearranging the equation to solve for F:
F = 1600 N / 6
F ≈ 267 j
Therefore, the force that the construction crew must apply to the lever is approximately 267 j. So, the correct answer is B.
