Question: 

Calculate the forces $F_A$ and $F_B$ that the supports exert on the diving board of Fig. 9–49 when a 52-kg person stands at its tip.

  1. Ignore the weight of the board.
  2. Take into account the board’s mass of 28 kg. Assume the board’s CG is at its center.
Problems 4 and 5.

Quick Answer: 
  1. $F_B = 2.0\times10^3\textrm{ N, } F_A = -1.5 \times 10^3 \textrm{ N}$
  2. $F_B = 2600 \textrm{ N, } F_A = -1800 \textrm{ N}$
