This question does NOT need to be solved, but I would appreciate some clarification. -------- PROBLEM: Collar A has a ramp that is welded to it and a force P = 5 lb applied as shown. Collar A and the ramp weigh 3 lb, and block B weighs 0.8 lb. Neglecting friction, determine the tension in the cable. ------- Can you explain in detail how to do the constraint equations ( in general)? And then specifically explain in this case why it is XB/A and how the two tension from the cable with block B does not effect the equation (figure four)? I understand how to solve it but I am still having trouble with the constraint equations.
