Conservative Quantities:
Considering a uniform disk rolling without slipping on an inclined plane, and
the inclined plane is on a smooth table, please find four constants during
this process. The radius of the disk is a and the mass of the disk is m, while
the mass for the inclined plane is M and the inclined angle is α.
You can use the generalized coordinates of x and s(sliping downward the
plane).
這題想不出來...
有人可以指點一下嗎？
感謝!!
