The change of the seat Angle affects significantly the tangential force, the efficiency of the force, and action efficiency.
改变坐角显著影响脚蹬切向力、有效力及作用效率的大小。
Do the tangential force, the mormal force, the resultant force and their directions during oscillation of a simple pendulum change?
那么单摆在振动过程中，切向力、法向力及合力的大小和方向是否在变化?。
Provided two contact bodies are in the critical state of relative sliding, the tangential force is proportional to the vertical force.
假设当两个接触面处于相对滑动的临界状态时，切向力与垂向力成正比。
