8. The figure shows a uniform beam ( = 1200 kg) that extends beyond its support like a diving
%3D
board. Such a beam is called a cantilever. The forces acting on the beam are those due to
the supports, and the force of gravity which acts at the CG (center of gravity), 5.0 m to the
right of the right-hand support. Calculate F, and F
