刚性轻杆连接的质量相等的两质点球系统的力学问题研究

A research of mechanical properties of two equal mass particles jointed by a rigid light bar

从刚体的基本性质出发,导出了刚性轻杆连接的质量相等的两质点球系统的某些力学特性:刚性轻杆连接的质量相等的两质点球系统,在沿杆方向上两质点球的动量分量相等,所受的冲量分量也相等,并利用这些特性解决了该系统的某些复杂的力学问题.

AcCording to the basic character of rigid body, the mechanical characteristics of two equal mass particles jointed by a rigid light bar： the momentum and impulse along the bar are equal, using these characteristics, some complex motions of this system can be solved.
