Because of heavy downpour, portions of a pathwalk got flooded, that needed the placing of foot bridges made of pieces of lumber, 3 m long. Each piece of lumber rests on two end supports that elevate them above the water. Neglecting the weight of the pieces of lumber, determine the maximum weight each support is to resist if a person weighing 800N walks across the foot bridge.
