Water from a stationary nozzle impinges on a moving vane with turning angle θ = 120. The vane moves away from the nozzle with constant speed, U = 10 m=s, and receives a jet that leaves the nozzle with speed V = 30 m=s. The nozzle has an exit area of 0.004 m 2. Find the force that must be applied to maintain the vane speed constant.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.
