This is a simple harmonic oscillator (SHM): spring with spring costant k, attached with mass m, and damping constant b/htdocs/ntnujava/ejsuser/2/users/ntnu/fkh/drivenspring_pkg/drivenspring.propertiesFull screen applet or Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
F(x) = -k*dx-b*vx ; where dx is the change of spring length L-L0
Another driven force is applied to the SHM (you can adjust the amplitude d, and the period/frequency of the applied force).
Try to find out under what condition, the SHM will have larger amplitude.
