A house painter is standing on a uniform, horizontal platform that is held in equilibrium by two cables attached to supports on the roof. The painter has a mass of 75.0 kg and the mass of the platform is 20.0 kg. The distance from the left end of the platform to where the painter is standing is d = 2.00 m and the total length of the platform is 5.0 m. (a) How large is the force exerted by the left hand cable? (b) How large is the force exerted by the right hand cable? [Hint: You can place your axis in any convenient location if the object is not rotating.]

Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.
