A 10 m long board that has a mass of 8 kg is held up by two vertical ropes. The left rope is 3 m from the left end of the board, and the other rope is 2 m from the right end of the board. A 55 kg box sits 2 m from the right end. Find the tension in the rope on the left. Hint:
- With forces applied at different places, this is a beam problem
- pick a pivot point
- measure all distances from the pivot point
- Apply ΣT=0
- Don't forget torque = force x dist, so you need to multiply the masses by g= 9.8 m/s²
- If you need more information, apply ΣF=0
