Two painters stand on a 10.0mlong 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 Jery 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). Darny - 92 kg Jeny - 68 kg mass plank 300 kg Determine the force which the rightpillar exerts on the plank?

Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.
