Unformatted text preview: N5: Statics Problem: A person of mass m walks across a beam of mass M. The beam is held up by two supports, one at each end. What is the force exerted by the left support as a function of where the person stands on the beam? A 1-kg rock is suspended by a massless string from one end of a 1-m measuring stick. What is the weight of the measuring stick if it is balanced by a support force at the 0.25-m mark?
