a person whos mass is 102 kg stands on a beam supported by two ropes , A and B, he is standing on one foot to help you solve this problem.what is the tension of the two ropes? the entire beam itself is 4.56 m and the person is stading from left to right in 1.59 m.

Take moments about each of the rope support in turn.
L=4.56 m, Ta & Tb are the rope tensions
distance of person from support A = 1.59
Moments about A
=102 kg * 1.59 - Tb*4.56 = 0
Solve for Tb.
Solve Ta similarly, by taking moments about B.
