    Spring damper system equation of motion

    Still not 100% sure on this Q factor, hard to see how it applies without an example. Q = \frac{1}{2\zeta} Q = \frac{1}{2*0.0256} Q = 19.53 Q = 2\pi*\frac{Energy Stored}{Energy Lost Per Cycle} \frac{Q}{2\pi} = \frac{Energy Stored}{Energy Lost Per Cycle} 3.11 = \frac{Energy...

    Spring damper system equation of motion

    I moved the mass to the inner radius i guess to simplify the system, honestly not sure, its the way I've been taught this semester to do it. So if i had the original system the mass would be M1 But now I've moved it to the inner radius The mass is now M2 For it to still be the same...

    Spring damper system equation of motion

    Homework Statement A 10 kg block is displaced 20 mm and released. If damping coefficient is 100 N.s/m, how many cycles will be executed before amplitude is reduced to 1 mm or below? The stiffness of the spring is k=20000 N/m. Homework Equations The Attempt at a Solution I...
