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