1. The problem statement, all variables and given/known data [PLAIN]http://img846.imageshack.us/img846/6546/statics.png [Broken] 2. Relevant equations Fy = F*cosθy Fh = F*sinθy Fx = Fh*cosφ = F*sinθy*cosφ Fz = Fh*sinφ = F*sinθy*sinφ 3. The attempt at a solution I'm having a lot of trouble drawing vector AD in a free body diagram. I think I need to draw one as that will help me further understand the solution that is worked out. I'm just having trouble identifying the angles that I should utilize and where on the diagram they should be placed. If someone could possibly draw up a diagram that helps with identifying what is what that would be very helpful. Fy = F*cos30 Fh = F*sin30 You could say my main problem is identifying which is φ, I just cannot tell from the picture at all. What exactly is φ defined as, my book's definition is pretty vague. Or am I going about this the wrong way?
