A uniform 1450 kg beam that is 18 m long is balanced on two vertical support beams at either
end of the beam (see figure 9-8). A crate which weighs 520 kg is positioned 4.0 m from the first
support beam. Calculate the force on each of the vertical support beams.
A boy of mass 35.0 kg is standing on a uniform plank of mass 23.5 kg and length 6.00 m (Figure 11-63). The plank sits on two supports, one at the left end and the other 1.50 m from the right end. What is the maximum distance x at which the boy can stand on the overhanging part of the plank without the plank starting to tip? (Hint: When the plank begins to tip, what happens to the force exerted by the left-end support?)
