A 10 m beam of mass 295 kg extends over a ledge. The beam is not attached, but simply rests on the surface. A 63 kg student intends to position the beam so that he can walk to the end of it. How far from the edge of the ledge can the beam extend?

Answer 1

(295 kg)((10.0 m)/2 - x) = (63 kg)(x)
solve for x
x = 4.12
