[SOLVED] Finding Tension in Scaffolding
A 656N window washer is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 171N and is 4.58m long. Assume the window washer stands 1.33m from the left end. What is the tension in both ropes. (Answer in N)
Static Equilibrium States [tex]\Sigma[/tex]Torques=0 also [tex]\Sigma[/tex]Forces=0
I first solved for the center of gravity, using the left end as a datum using the equation (sum of moments)/(sum of masses) = center of gravity. Then, using my new point as the lever arm for the board's weight, I solved for torque in the downward direction and thought that tension should have to be equal. I am doing this as a part of an online course, and submitted my answer, which was incorrect. I could really use help, thanks.
