Two painters stand on a 10.0m long plank of mass 300 kg. The plank rests on two pillars separated by 6.00m. Danny has a mass of 92.0 kg and stands 3.00m from the left end of the plank and Jerry has a mass of 68.0 kg and stands 1.50m from Danny. Assume that the plank is not nailed to the pillars (the plank only rests on top of pillars). Danny = 92 kg Jerry = 68 kg 3m mass plank = 300 kg 1.5 m 2m 6m 2m Determine the force which the left pillar exerts on the plank.
