Water from a stationary nozzle strikes a flat plate (directed normal to the plate as shown in the figure). The velocity of the water leaving the nozzle is 15 m/s and the nozzle area is 0.01 m2. After the water strikes the plate, subsequent flow is parallel to the plate.

a. Find the horizontal force that must be provided to the plate by the support.
b. Find the maximum longitudinal normal tensile stress in the support post if it is a hollow square cross section as shown. Model the force due to the water as a point load.
c. Find the maximum transverse shearing stress in a cross section of the post.
