Aconcrete box culvert with manning’s roughness coefficient n = 0.015 and a rounded entrance (ke = 0.2) is to be designed to carry the design flow of 9.8 m3 /s. the culvert slope is 0.3% and the length is 38.0 m. if the maximum-allowable headwater level is 2.8 m above the culvert invert, determine the size of the box culvert with free-outlet conditions and verify the flow type

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.
