Seite 34 - ... the sum of the moments of the forces which tend to turn the body in one direction must be equal to the sum of the moments of those which tend to turn it in the opposite direction about the same axis.
Seite 414 - Here, too, we drop the consideration of friction and the weight of the piston. 536. The velocity of the water flowing from the sucking pipe into the barrel should be equal to the velocity with which the piston moves. For if it be greater, less work will be done than the pump is competent to effect; and if it be less, a vacuum will be produced below the piston, which will therefore be moved upwards with great difficulty. If v be the velocity of the water in the sucking pipe, d the diameter of that...
Seite 352 - A, if the whole apparatus be placed under the receiver of an air pump, and the air...
Seite 386 - ... water. A body in motion appears to be resisted by a stagnant fluid, because it is a law of mechanical nature that force must be employed in order to put any body in motion. Now, the body cannot move forward without putting the contiguous fluid in motion, and force must be employed for producing this motion.
Seite 388 - ... is equal to the weight or pressure of a column of the fluid, whose base is equal to the...
Seite 413 - Hence the total pressure upon the side of a vessel containing water will be equal to the weight of a column of water whose base is equal to the area of...
Seite 409 - It is, on the other hand, pressed downwards by the whole force of the atmosphere, which is equal to the weight of a column of water of the same base, and thirty four feet high.
Seite 387 - the resistance must vary as the number of particles which strike the plane in a given time, multiplied into the force of each against the plane; but both the number and the force are as the velocity, and consequently the resistance is as the square of the velocity.
