1m 3 m B A boy stands out at the end of the diving board, which is supported by two springs A and B, each having a stiffness of k = 15kN/m. In the position shown the board is horizontal. The boy has a mass of 40-kg. Determine the angle of tilt which the board makes with the horizontal after he jumps off. The weight of the board is 5kg/m. The board is assumes as rigid.
