In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.
A uniform beam AB AB\,AB of length 10 m is supported by a pivot at its midpoint. An object of mass 16 kg is placed at the end AAA. A second object of mass 20 kg is placed on the beam at a distance w w\,w m from the pivot, on the opposite side of the pivot from AAA, so that the beam rests horizontally in equilibrium.
