Page 269 - The resistance which is opposed to a pump rod in raising water, is ~equal to the weight of a column of water whose base is the area of the piston, and...
Page 12 - But at last, when it is brought to the test of close reasoning, there is not even that thin decoction of it left. It is a presumption impossible in the domain of thought. It is precisely no other than the putting of that most unphilosophical proposition, that two bodies can occupy the same space at the same time.
Page 151 - Hence, the moment of inertia of a body with respect to any axis is equal to the moment of inertia with respect to a parallel axis through the...
Page 35 - Hence, the moment of the resultant of two forces is equal to the algebraic sum of the moments of the forces taken separately. 53. Forces Acting at Different Points. Parallel Forces.— We have thus far considered forces acting upon a single particle, or upon one point of a body. If, how- Fia 33...

The moment of inertia of a body, with respect to an axis, is the sum of the products obtained by multiplying the mass of each elementary particle by the square of its distance from the axis; hence, the moment of inertia of the same body varies according to the position of the axis.
