Question
Problem 3.4 As illustrated in Fig. 3.30, consider two divers
preparing to dive into a pool in a sequence. The horizontal
diving board of uniform thickness is mounted to the ground
at point O, has a mass of 130 kg, and is 1 = 4 m in length. The
first diver has a mass of 86 kg and he stands at point B, which is
the free end of the diving board. The second diver has a mass of
82 kg and he stands at point A, which is the center of gravity of
the board. Furthermore, point A is equidistant from points O
and B.
