1. The problem statement, all variables and given/known data The ceiling-mounted bicycle rack (shown in "Capture" image in attachments) with dimensions p = 50 mm, q = 1000 mm and r = 150 mm for a bicycle that weighs F = 200 N. The rack is to be made from two parts, ABC and BD, cut from a steel tube and then welded together at B. Determine the forces and moments acting on the whole rack, ABCD. 2. Relevant equations The only equations that I can see would be relevant here are the force and moment equations: M = (F*d) Ʃ M = 0 Ʃ F = o 3. The attempt at a solution I have found M(of B) and M(of C) by doing the following: M(of B) = 200*0.15 = 30Nm Clockwise Therefore, 30 = 0.05*F(at A), so F(at A) = 600N So... M(of C) = 1.05*600 = 630Nm Clockwise. So I have found M at points B and C, and the force at A, however I am not confident that is what's required of the question. What does it mean by "the forces and moments acting on the whole rack ABCD"??
