While standing on a long board resting on a scaffold, a 70 kg painter paints the side of a house. The boards length across the scaffolding is: end of board to scaffold is 1.5m, then from one end of the scaffold to the other end of the scaffold is 2.5m, then from the end of scaffold to end of the board is 1.5m. If the mass of the board is 15 kg, how close to the end can the painter stand without tipping the board over?© BrainMass Inc. brainmass.com December 24, 2021, 5:15 pm ad1c9bdddf
Torque of board from scaffolding:
Center of board is center of mass which is ...
