A reservoir has a sloping wall which is 30 to the vertical. The wall is pierced by a circular hole 1m in diameter which is closed off by a steel plate valve of the same dimension but having a frictionless hinge at "A". A horizontal support arm AB is 1m in length and attached to the plate as shown in the sketch. The weight of the arm is sufficient to keep the plate valve closed when there is no water in the reservoir. Calculate the mass that must be applied at "B" to keep the valve closed until the water reaches a height of 700mm above the valve centreline. B 700mm Given: F, = P9AY, Im Sin k D + Y, Im nd* Ak mass 64 P water = 1000kg/m 30
