## Homework Statement

A 20-lb force is applied to the control rod Ab as shown. Knowing that the length of the rod is 9 in. and that α=25°, determine the moment of the force about point B by resolving the force into horizontal and vertical components.

The first image I provided was given.

## Homework Equations

M=Fd

Law of Sines and other basic trig

## The Attempt at a Solution

The second Image I provided is as far as I can get. Assuming what I did so far is correct I'm not sure where to go from here. I know that M=Fd but can someone tell me what I am supposed to use for F and d in my cases. Do I also need to calculate the length between point A and the 90 degree angle?

Thank you.
