Ascheme for finding the internal volume vb t of a gas cylinder consists of the following steps. the cylinder is filled with a gas to a low pressure p1, and connected through a small line and valve to an evacuated reference tank of known volume va t . the valve is opened, and gas flows through the line into the reference tank. after the system returns to its initial temperature, a sensitive pressure transducer provides a value for the pressure change δp

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.
