The MIT varsity diving team is practicing their back flips on the Z-center's diving boards.The diving boards have a total length of 3 m, width of 0.5 m, and thickness of 0.1 m. The core of the boards is made of a Douglas fir wood with an estimated Young's modulus E of 0.6GN/m2. Let us approximate the diving board as a clamped-free beam, neglecting the springboard support at the midspan of the diving board and the weight of the diving board
