The left leg kicks to counter-balance the vertical forcecomponent of elevating and recovering right arm.
左腿打水来平衡右臂的抬升和空中移动长生的垂直分力。
2
The vibration and noise of the pump. 7 because the rotary inertia forcecomponent inside the pump is low, can work under high rotation speed.
⑥泵的振动和噪声极小。 ⑦因为泵内的回转部件惯性力较低，可在高转速下工作。
3
Trust force and bending moment result in heat expansion are calculated by adopting beam theory of mechanics of materials and applying forcecomponent analysis method.
