Question
A square plate is suspended vertically from one of its edges using a hinge support as shown in figure. A water jet of 20 mm diameter having a velocity of 10 m/s strikes the plate at its mid-point, at an angle of with the vertical. Consider as and neglect the self-weight of the plate. The force (expressed in N) required to keep the plate in its vertical position is _________
Correct answer
7.4 to 8
Solution
Diameter of jet
Area of jet
Velocity
Angle of jet with the plate
Force normal to the plate
Let the side of the square plate be . The jet strikes at the mid-point ( from hinge) and force is applied at the bottom edge ( from hinge).
Taking moments about the hinge:
