Therefore they are pushed upward by a force equal to the difference between their weight and the weight of an equal volume of the colder air.
A body immersed in a liquid is pushed up by a force equal to the weight of the liquid that it displaces.
Therefore any object in the air is lifted up by a force equal to the weight of the air it displaces.
If a force equal to one hundred weight will raise a certain body along an inclined plane, a force equal to two hundred weight will raise two bodies exactly similar, and thus the effect is proportional to the cause.
This is true even when the force leaves the body as it found it, in a state of absolute rest; as when we attempt to raise a body of three tons weight with a force equal to one ton.
But does not a force equalto two hundred weight actually contain in itself two forces each equal to one hundred weight, which, if employed apart, would separately raise the two bodies in question?
But does not a force equal to two hundred weight, actually contain in itself two forces each equal to one hundred weight, which, if employed apart, would separately raise the two bodies in question?
This is true even when the force leaves the body as it found it, in a state of absolute rest; as when we attempt to raise a body of three tons’ weight with a force equal to one ton.
The principle of this machine admits of easy explanation: When a fluid issues from any vessel in which it is confined, that vessel suffers a force equal to that with which the fluid escapes from it, and in the opposite direction.
Now in this process, the air above the piston, which presses on it with a force equal to fifteen pounds, has been raised one hundred and forty-two feet.
It is plain, therefore, that the sulphat of soda will not be decomposed, since a force equal to 8 cannot be overcome by a force equal only to 6.
Suppose, for example, a bird weighs twelve ounces, and it strikes the air with a force equal to sixteen, is it not clear that it must rise with a force equal to four?
If the elasticity of a body be perfect,” added Mr. Seymour, “it will restore itself with a force equal to that with which it was compressed.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "force equal" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
