They are reinforced to resist the sideways force exerted by the liquid in these containers.
加固后它们才能够克服这些容器中的液体所施加的侧力。
The higher it climbs, the greater the force exerted by blood on the walks of the arteries when the heart beats.
血压升得越高,心脏跳动时血液对动脉壁施加的压力就越大。

This is the force exerted by the spring on the mass.
这是弹簧对物体的作用力
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
For example, how do I know that when I pull the spring the first time for the mass, it exerted the same force when I pulled the spring the second time for the elephant?
例如 怎样才能知道,第一次连着物体拉弹簧时,产生的力和,第二次连着大象拉弹簧时产生的力是相等的呢
