Problem 5 You have gathered an experimental step response from a measurement instrument in order to assess its dynamic parameters. The measurement instrument is a pressure transducer whose output is a voltage. The pressure input stepped up from a value of 0 gage pressure to a pressure of 10 psi. a. Using the step response (on the right), estimate the parameters of the measurement system. b. Write the transfer function of the system.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

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.

Fluids at rest possess no flow energy. a)- true b)- false
