A uniform beam (mass M = 64.0 kg and length L = 4.90 m) is supported by two triangular supports that are placed a distance D = 2.94 m apart, as shown below. The left-most support is at the very end of the beam. A person (mass m = 22.0 kg) starts walking at constant speed v along the beam, beginning from some point between the two supports. How close can the person get to the right-most end of the...

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?
