Homework Statement
A shock absorber is to be designed to limit its overshoot to ##15## percent of its initial displacement when released. Find the damping ratio ##\zeta_0## required.
Homework Equations
The Attempt at a Solution
My question is since log decrement, ##\delta = \ln\frac{x_1}{x_2} = \frac{2\pi\zeta}{\sqrt{1 - \zeta^2}}##, for a 15% overshoot, do I set ##\frac{x_1}{x_2} = 1.15## and then solve for ##\zeta##?
