1. The problem statement, all variables and given/known data 2. Relevant equations T1/T2=eμs*β where T2 is the larger tension and β is the angle between the tensions. 3. The attempt at a solution Isolating each pipe: W1 = 50*9.81 = 490.5N For pipe B, β = (2π)/3 For pipe C, β = π/3 For pipe B, T2 = 490.5N, so I have: 490.5/T = e0.25*((2π)/3) T = 290.6N Now here is where I made the wrong choice. On pipe C, I chose W2 to be T2 because if equilibrium is maintained, it would make sense for W2 to be going down, not up. This got me the wrong answer. Then I tried making T2 = T instead: 290.6/W2 = e0.25*(π/3) W2 = 233.7N m = 233.7/9.81 = 22.8kg 22.8kg is the right answer. I am just not understanding why T is the stronger tension on pipe C. It seems to me that it would cause the 50kg weight to start falling.
