A man of mass 65.2 kg stands on a scaffold supported by a vertical rope at each end. The scaffold has a mass of 22.7 kg and is 2.4 m 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?

the cg is at 1.2m from the left, and the man stands at (1.2+.4) from the left.
sum moments around the left end:
65.2*g*1.6+22.7*g*1.2  Tr*2.4=0 solve for tension in the right rope Tr.
check carefull that sum of moments equation. 
How about for the left rope? Would it be the same thing? or negative instead?
