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). Determine the force which the left pillar exerts on the plank. Determine the force which the left pillar exerts on the plank. Determine the force which the left pillar exerts on the plank.
