A 20 kg, 10 m long aluminum painter’s plank is supported by a cable at each end. When the painter is standing somewhere on the plank, the left cable exerts a force of 400 N and the right cable exerts a force of 600 N. Determine the mass and location of the painter standing on the plank. What assumptions did you make? Main focus should be conceptually deriving the Equations and less focus on numerically solving equation.
