1. The problem statement, all variables and given/known data [PLAIN]http://img849.imageshack.us/img849/3716/staticeqpulley.jpg [Broken] Hopefully the image showed up. If not, here's the link: http://img707.imageshack.us/img707/3716/staticeqpulley.jpg" [Broken] Sorry for the low quality pictures. Hopefully it will do though. The question is: Relate the traction force F3 to the weight mg and the angle theta. 2. Relevant equations They give us that the tension T is uniform throughout the string (i.e. F1, F2 = T). F3 acts along the horizontal. 3. The attempt at a solution I resolved the diagonal forces into horizontal and vertical components. Since θ1 and θ2 are equal I just call them both θ. The system is in static equilibrium so the total force is zero. So I expand the equilibrium equations out as follows: -F1cosθ - F2cosθ + F3 = 0 and -F1sinθ + F2sinθ = 0 Also, T = mg Do I just sum the two equations above and set them equal to mg? That doesn't make sense since the sum is 0, and mg is certainly not 0. Or should I sum them and subtract mg from the sum? Any help would be appreciated! Thanks.
