The crew on peg leg Petes' ship have mutinied. Now Pete finds himself walking the plank. The plank is 4.5m long and has a mass of 13kg. 3.6 meters of the plank extend out over the waters. The plank pivots on a small rail at the edge of the ship, this is the only point of the plank in direct contact with the ship. The remaining meter of the plank is held in place over the deck by the metal bar. The bar is .6m from the pivot. If Pete has a mass of 111kg, what is the torque provided by the bar when Pete is at the end of the plank?
