(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The pruner multiplies blade-cutting power with the compound leverage mechanism.

If F = 26 is applied to the handles, determine the cutting force generated at A . Assume that the contact surface at is smooth.

2. Relevant equations

M = F x d

3. The attempt at a solution

I drew the free body diagram of the upper handle. I took the moment at point B.

M_b = -26N (150 mm) + (Cutting Force) (60 mm) = 0 -> Cutting force = 65 N.

The answer is incorrect. I don't understand how that could be incorrect. There's no other force acting on the upper handle.

I tried looking at the lower handle, but there's point C and D which I can't figure out the FBD for. Please help! I really don't understand what is going on. I've been looking at that picture for half and hour and nothing. Dumb it down for me. I don't need an answer. I just need to know what is missing or going on. Please!
