1. The problem statement, all variables and given/known data The system of 2 spheres is in equilibrium. Figure: . If the weight of the second sphere P2=20N, ABC=60 degrees and BAC=30 degrees, find the weight of the first P1 and the force that is applied on the drum of the pulley. 2. Relevant equations P1=m*a 3. The attempt at a solution Everything is in equilibrium (no acceleration). I think I should solve Newtons 2nd law for P2 to tell me the tension, but I have no acceleration for P2. I don't know how to solve it.
