Описание: A uniform plank of length 6.00m and mass 30.0kg rests horizontally across two horizontal bars of a scaffold. The bars are 4.50 m apart, and 1.50 m of the plank hangs over one side of the scaffold. How far can a painter of 70.0 kg walk on the overhanging part of the plank before it tips? Hint: What happens to the interactions (especially at the “far” bar of the scaffold) when the painter starts to tip?
