a 10m uniform beam of weight 100 N is supported by two ropes at the ends. if a 400 N person sits at 2m from the left end of the beam, what is the tension in the left rope?
The moment about the right rope attachment point must be zero. Use this fact to solve for the Tension on the left side rope.
10N *2 - T*10 = 0
Solve for T.
