Homework Help: Torque and Forces

  1. Nov 15, 2009 #1
    A window washer is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 200 N and is 3.00 m long. What is the tension in each rope when the 700 N worker stands 1.00 m from one end?

    My question is that whether there is a normal force exerted on the person by the scaffold? Thanks a lot.

    because gravity pulls on the man the scaffold must exert an equal but opposite force up on the man. Otherwise the man would fall to his potential death.
