Side 9 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it is compelled by forces to change that state.
Side 116 - ... directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
Side 201 - Kelvin has shown that if a drop of water were magnified to the size of the earth the molecules of water would be of a size intermediate between that of a cricket ball and of a marble.
Side 202 - The moment of a force about any point is the product of the magnitude of the force and the perpendicular distance from the point to the line of action of the force.
Side 36 - If three forces acting at a point are in equilibrium they can be represented in magnitude and direction by the three sides of a triangle taken in order.
Side 36 - If any number of forces acting at a point can be represented in magnitude and direction by the sides of a POLYGON taken in order, they are in equilibrium.
Side 116 - that every particle of matter in the universe attracts every other particle, with a force whose direction is that of the line joining the two, and whose magnitude is directly as the product of their masses, and inversely as the square of their distances from each other.
Side 230 - Troy of wheat, taken from the middle of the ear, and well dried, should make one gallon of Wine measure, and 8 such gallons make a bushel.
Side 201 - Inertia of a surface about an axis through its center of gravity und perpendicular to the surface is the sum of the products obtained by multiplying each elementary area by the square of its distance from the center of gravity of...
Side 170 - All the world and his wife have been shown exactly how the " artist " dresses and undresses ; we feel that the sum of human knowledge has been appreciably augmented. But on the principle that you cannot have too much of a good thing, Zaza does it all, or nearly all, over again. Having combed her hair in Act I., she combs it once more in Act IV., and offers you a further piece of minute realism by removing the loose ends of hair from the comb and throwing them out of the window. Then she dusts the...
