A jet of water of diameter 25mm strikes a 200mm x 200mm square plate of uniform thickness with a velocity of 1Om/s at the centre of the plate which is suspended vertically by a hinge on its top horizontal edge. The weight of the plate is 98.1N. The jet strikes normal to the plate. What force must be applied at the lower edge of the plate so that plate is kept vertical? If the plate is allowed to deflect freely, what will be the inclination of the plate with vertical due to the force exerted by the jet of water? , (10 Marks) I of 2
