Urgent! Damped Simple Harmonic Oscillation
The thread topic says 2 masses, but there is actually only one!
I'm not asking for the complete solution for this problem; I simply just don't know WHERE to start... The question is as follows:
In Figure 15-15, a damped simple harmonic oscillator has mass m = 290 g, k = 70 N/m, and b = 75 g/s. Assume all other components have negligible mass. What is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 20 cycles (Adamped / Ainitial)?
The figure shows a "Rigid support" at the top, to which a spring is hooked. At the bottom of this spring is a rectangular mass. At the bottom of this mass extends a vane which falls into water as the spring elongates.
variables listed: k, m, b (damping constant)
Please help if at all possible!
