1. The problem statement, all variables and given/known data There are three connected bars (Bar 1, 2, and 3). Bar 1 is attached at on end to a pivot, point A, where it can rotate and at the other end to Bar 2, point B. Bar 2 is connected to Bar 1 at point B where it is free to rotate and translate. Bar 2 is connected at the opposing end to Bar 3, point C. Bar 3 can only translate horizontally. If there is a known horizontal force and displacement of Bar 3, what is the moment at point A so that the system is in equilibrium? 2. Relevant equations M = F*rprep M1 = M2 :. F1*rperp = F2*rprep 3. The attempt at a solution The force at point A would be the known horizontal force on Bar 3 * rprep from point 3 to point 1. Right? This would be true regardless of the angle of Bar 2 correct?
