9. Oscillating Screw

When placed on its side on a ramp and released, a screw may experience growing oscillations as it travels down the ramp. Investigate how the motion of the screw, as well as the growth of these oscillations depend on the relevant parameters.

将螺丝置于斜面上并释放，它可能会在沿斜面向下运动的过程中产生逐渐增大的振荡。研究螺丝的运动以及其振荡是如何受相关参数影响的。
