Hello, I've been unable to figure this question about tension and torque out. 1. The question is: calculate the torque about the front support on the right of a diving board exerted by a 70 kg person 3.0 m from that support. This is a crude diagram of a person on a diving board, where D = a diver, and || means a diving board support: ____________________________________________D ||<----1.0m---->||<-----------3.0m--------------> ||- - - - - - - - - || ||- - - - - - - - - || 2. Relevant equations: τ = Fd F = ma Fup = Fdown / Fleft = Fright 3. I get these equations: Fup = Fdown F1 + F2 = Mg + mg (where mg = downward force of diver, Mg = downward force of diving board at center of board) F1 + F2 = M(9.8) + 686 τcw = τccw Mg(1.5) + mg(3) = F2(1) (assuming F2 is the upward force for the middle support?) Mg(1.5) + 70(9.8)(3) = F2(1) Mg(1.5) + 2058 = F2 I assume the pivot point to be on the far left of the board. The main problem problem with both of these are that I end up with equations that have two variables. Also, I don't have M, which is the mass of the diving board - how would I figure this out? What's wrong in my process to get the answer?
