(17%) Problem 4: A painter (of mass 71 kg) needs to reach out from a scaffolding to paint the side of a building, so he lays a plank across two bars of the scaffolding, and puts a heavy bucket of mass 67 kg directly over one of the bars (see figure). You can assume the plank is massless, and is long enough to reach to the other building. L d ©theexpertta.com If the bars are separated by a distance 1.1...

A uniform aluminum beam 9.0 m long, weighting 300 N rests symmetrically on two supports 5 m apart
A uniform aluminum beam 9.0 m long, weighting 300 N rests symmetrically on two supports 5 m apart. A boy weighting 600 N is standing initially at position x = 4 m to the right from support A a. Find the normal forces exerted by both supports on the beam b. Imagine now that the boy starts walking to the right along the beam. How far beyond the point B can the boy walk before the beam tips?

A plank of uniform density and length L is placed on a level surface. A 500g mass is placed at a point one fifth of the way down the length of the plank and the non-weight end of the plank is extended over a sharp edge. At a point when two thirds of the plank has been extended the plank + weight system is perfectly balanced. What must the mass of the plank be for this system to balance at...
