| Abstract: | To start with no slide condition of pure rolling rigid body: this article pressent a new method to judge the direction of static fractional force exerted to pure rolling rigid body according to the characteristic that the direction of static fractional force is oppo-sited to the tendency of relative motion of the body. |
| |
| Keywords: | No slide condition Relative motion tendency Static fractional force |
