A crowbar is being used with an actual mechanical advantage of 8. If the input force is 400 newtons on the 0.3-meter-long end of the crowbar, what is the output force on the short end?(1 point)

Question

A 50 n
B 960 n
C 3,200 n
D 120 n

Answer 1

To find the output force, use the formula for mechanical advantage:

Mechanical Advantage = Output Force / Input Force

In this case, the mechanical advantage is given as 8, and the input force is 400 newtons. We can rearrange the formula to solve for the output force:

Output Force = Mechanical Advantage * Input Force

Output Force = 8 * 400 = 3200 newtons

Therefore, the output force on the short end of the crowbar is 3200 newtons.

The answer is C) 3,200 N.
