Homework Statement

Sorry, By and B should be in lbs, not lbft

My work just shows how I attempted to find the force B. According to my book, the force B should be 2140 lb.
I'm really not sure if I handled the incline (force B) correctly. I know it's supposed to be perpendicular to the point of contact.
Does anyone see where I went wrong? As far as I can tell, the width of the beam (1.2ft) isn't important for finding any of the vector components.
