Modeling analysis of friction stimulating vibration for rudderpost and bearing framework of shipping Aileron servo pull rod should be vertical to the shaft of aileron basically. 船舶舵轴及轴承结构摩擦激振建模研究副翼舵机拉杆应基本上垂直于副翼转动轴线。
Robbins continues by writing that friction is useless unless the body is braced toward the direction of pull. 罗宾斯在书中说道,如果身体没有受到牵引力的作用,那么摩擦力也是没有任何用处的。
Wet hair friction, easy to chaos, easy to pull injury. 湿头发摩擦,很容易混乱,易拉受伤。
During the friction resistant testing of the engine crankshaft thrust bearing, there are two most important parameters that are the push& pull force and the temperature of the thrust plane. 汽车发动机曲轴止推瓦止推耐磨性能试验中,止推面推拉力、止推片温度是两项重要的控制检测参数。
