'Two masses suspended by two springs in tandem are subject to a driving motion.
'The driving motion is sinusoidal, with an increasing frequency characterized by an increasing sweep rate.
'The system is described by mass and by spring length and stiffness.
'The output graph shows the driver motion on top, and the response of the two masses below.
'spring and mass animation
'response of masses and springs to displacement by a sinusoidal driver
WINDOW -500, -1200,500, 100
'set up differential equations of motion for top and bottom masses
