理论力学经典问题数值模拟课件，平底凸轮的动画演示。显示了不同动点的选择，相对运动轨迹的形式。-Numerical simulation of the classic problems of theoretical mechanics courseware, flat cam animation. Shows the different choices of fixed points, the relative trajectory of the form.

用于小球运动轨迹的演示，演示较为立体化，直观明了，程序比较简单-For ball trajectory demonstrations by more three-dimensional, simple and clear, relatively simple procedures
