An undershot waterwheel consists of a series of flat vanes, mounted radially on a wheel of
large diameter, which are struck normally by a jet of water 0.3 m in diameter. If the velocity
of the water leaving the nozzle is 7.5 m/s and the velocity of the vanes is 4.8 m/s, determine:
i. The force exerted by the jet on the vanes;
ii. The work done per second;
iii. The hydraulic efficiency.​

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
