The diving board shown in Fig. Q4 has been designed for people upto 2 stone in mass (Weight = 1246N). The board is made out of Glass Reinforce Plastic with a Young's Modulus of 20GPa, a yield strength of 80MPa and weight of 744.2 N. For a 20 stone person standing stationary 150mm fro the right hand end of the board find: i. ii. the maximum deflection of the board iii. the position of maximum moment iv. the maximum stress and the factor of safety for the board. the reactions and moments acting on the board.

The diving board shown in Fig.Q4 has been designed for people upto
stone in mass (Weight 1246N). The board is made out of Glass Reinforce
Plastic with a Young's Modulus of 20GPa, a yield strength of 80MPa and
weight of 744.2 N. For a 20 stone person standing stationary 150mm fro
the right hand end of the board find:
the reactions and moments acting on the board
the maximum deflection of the board
the position of maximum moment
the maximum stress and the factor of safety for the board.
