A 8 m long board that has a mass of 12. Each end is held up by a vertical rope. A 60 kg box sits 3 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 problempick a pivot pointmeasure all distances from the pivot pointApply 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
