1. The problem statement, all variables and given/known data Blocks A & B each have mass 5kg, and all contact surfaces are frictionless. Determine the force F needed to keep the blocks in static equilibrium, and the forces on all contact surfaces. 2. Relevant equations I know I need to find where Fx= 0 and where Fy= 0. 3. The attempt at a solution Fx = Fcos20 Fy= Fsin20 - 5 kg Am I even close?
