## Homework Statement

Im having exam about Torque on monday and im trying to solve problems about it I stumbled with this problem, I cant solve it. I think im missing a fundamental concept about torque because of the fact that I dont understand how this problem was solved.

## Homework Equations

## The Attempt at a Solution

The problem is solved, I just need someone to tell me why when doing the sum of torques a 2000 cos 65 was used . I belive the torque should be the perpendicular component of the force to the rod or for the uniform boom. I wrote instead 2000 sin of 25 . any help please?
