Unformatted text preview: Homework 4 Due Tuesday October 6 http: nsgsun.aae.uiuc.edu AAE250 1. Consider the mass-spring damper system shown below. Assume no friction on the oor. The coordinate x is measured from the position of the mass when the spring is unstressed. AAE 250 x c=1 F m=4 k=4
a Write down the di erential equation for this system. Find the undamped natural frequency and the damping ratio. b Find the transient or free solution. Is the system underdamped, critically damped, or overdamped. Plot the transient solution versus time. c...
