Damped
Vibration -- Help |
The graphing window at right displays a solution to the differential equation x" + bx' + kx = 0. Adjust initial conditions by dragging the cursor over the left graphing window, in which x(0) is recorded on the vertical axis and x'(0) is recorded on the horizontal axis. Alternatively, set these values using the sliders along the bottom and left side of the initial condition window. Adjust the values of the damping constant b and the spring constant k using the sliders at bottom. Select the vertical scale for the graphing window using the buttons below it. Roll over the graphing window to display crosshairs and a readout of the coordinates.
