Avibratory system in a vehicle is to be designed with the following parameters: k-295 n/m, c-2n-s/m, m-13 kg. calculate the natural frequency of damped vibration

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
