摘要
经典理论中,按“接触点相对运动趋势”来确定“静滑动摩擦力”及“最大静滑动摩擦力”方向并不完全可靠。文中给出几个“静滑动摩擦力”及“最大静摩擦力”方向不与“相对运动趋势”相反的实例,并对理论力学、工程力学中有关内容提出有价值的修改意见。
It is not always successful when one tries to define the direc-tion of 'static friction' or 'the maximum static friction' according to the trendof relative motion of contacting points presented in classic theory. In this paper, several practical examples in this field are discussed. Somevaluable suggestions for modifing the concerned contents in Engineering Mechanicsare advanced.
