Question

A 9 m long board that has a mass of 14. Each end is held up by a vertical rope. A 45 kg box sits 1 m from the left end. Find the tension in the rope on the right.

Hint:

With forces applied at different places, this is a beam problem
pick a pivot point
measure all distances from the pivot point
Apply Στ = 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
