Question

If the input force applied to one end of a first-class lever is 8 N, and the fulcrum is located 6 m away from the input force but 3 m away from the output force, what will be the resulting output force?

Answer 1

16 N

Step-by-step explanation:

The ratio of output force to the input force is called mechanical advantage of the lever. Also, the ratio of input arm distance to the output arm distance is called mechanical advantage of the lever.

We have,

Input force = 8 N

Input arm distance = 6 m

Output arm distance = 3 m

We need to find the resulting output force. So,

`(F_o)/(8)=(6)/(3)\\\\F_o=16\ N`

So, the resulting output force is 16 N.
