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?

• Physics -

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.

• Physics -

How about for the left rope? Would it be the same thing? or negative instead?
