a 10-m uniform beam of weight 100N is supported by two ropes at the ends. If a 400N erson sits at 2.0 m from the left end of the beam, what is the tension in the right rope?

Answer 1

Sum the moments about any point. I will do it from the left end.

100N*5m+400N*2m-Tright*10=0
solve for Tright.

Now, sum the forces vertically.

Tleft+Tright-100N-400N=0 solve for Tleft.

Answer 2

130 N

Answer 3

A 10 m long uniform beam weighing 100 N is supported by two ropes at the ends as shown. If a 400 N person sits at 2.0 m from one end of the beam, what are the tensions in thr ropes
