弹簧的弹力会发生突变吗？

Is there Sudden Change in the ElasticForce of Spring?

当拆下波轮的螺钉后，由于弹簧的弹力作用使波轮向上弹出，从而使波轮轻易拆离离合器轴。

When a bolt of the impeller is dismantled, the impeller is popped upwards due to the elasticity of the spring, thereby the impeller is dismantled easily from a clutch shaft.

设计时要确保总摩擦力小于折回弹簧的弹力，这样当松开踏板时，弹簧才会弹回，油门才会闭合。

The amount of friction is designed to be some degree less than the return spring, so that when the pedal is released, it returns to the closed position.

But if I'm accelerating, the force exerted by the spring and therefore, the needle the weighing machine reads is m.

但是如果我在加速运动,那么弹簧的弹力,也就是称重机上指针的读数就是 m
