Unformatted text preview: Outputs and is changing at 0.5 Outputs /sec. Initially there is no input, but at time t = 2 a 15 Input step is applied. What is the system's output as a function of time? 3/. The jet blast hitting a screen subjects it to a force. Jet Blast k S m friction b x This force varies as shown below: 20s 40s 1600N 800N Assuming that m = 250 kg, b = 212.132 N-s/m and k S = 2000 N/m how far will the screen move in either direction (i.e. what are the minimum and maximum values of x )? At what times will these extreme displacements occur? Once the force has ceased, the screen will eventually settle down to within 2 cm of its equilibrium position. At what time will this happen? 4/. Assuming that L = 1H and C = 0.5625F, what value of R will make the system below critically damped?...
