1. The problem statement, all variables and given/known data I need to find the moment of A about D. We are given the Fg on the object to be 49N and the distance from A to D is 27.5cm. I've attached a drawing to help demonstrate. 2. Relevant equations MD= rA/D X F 3. The attempt at a solution I know the radius between A and D is 27.5cm but I'm not sure how to find out how much of the force is actually acting on D! I know I need to use sin or cos of a deduced angle (15 degrees or one relating to that). I'm not sure which trig operation or angle to use. Would anyone be able to shed some light on how to go about? Much thanks.
