3. A diver of weight W is springing on a rectangular cross-sectional diving board ABC. On a particular bounce, the diver reaches a height h above the end C of the board. Data are as follows: a = 3 m; L = 4 m; b= 400 mm; d= 65 mm; h= 500 mm; E = 12.6 GPa; W= 600 N. Find: a. The maximum static deflection and stress in the board b. The maximum dynamic deflection at end C c. The maximum dynamic stress in the board d. Also solve b. and c. if the supports at A and B are fixed, ie. the beam acts as a cantilever of length 3 m.
