A man is walking on a plank which ch is placed horizontally across two support so that equal length project at each end. If the plank is 5m long and has mass of 30kg, what is the greatest distance from each end at which the support can be placed so that a man of mass 80kg can stand any where on the plank without it falling off the support?
