A man of mass 76.1kg stands on a scaffold supported by a vertical rope at each end. The scaffold has a mass of 23.9kg and is 3.0m long. Suppose the man stands to the right from the middle of the scaffold that is a distance one sixth of the length of the scaffold. What is the tension in the right rope?
b).what is the tension in the left rope?

Sum moments about the right end.
Tl*3-23.9g*1.5-76.1g(d)=0 where d is where the man is standing.
1/6 length scaffold is .5m, so the man is standing at 1.5-.5=1.0 or d=1.0 check that.
solve for tension left Tl
