Practice Problem 6-3(a)

Practice Problem 6-3 (a)

Given:When a diver jumps on a diving board, he exerts a 840 N force on the end of a diving board. The board has a length of L = 4.0 m, a width of 0.6 m and a thickness of 5 cm. Let a = 1.2 m. Assume that the board is simply supported at its left end, and at x = a.

Req'd: Determine the maximum magnitude of the bending moment M_max in the board.

Sol'n: The bending moment with the maximum magnitude occurs at the main support (x=a):

M = F(L–a) = (840 N)(2.8 m) = 2352 N·m

M = 2.35 KN·m
