Fréquemment cités
Page 50 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.
Page 52 - Change of motion is proportional to the impressed force and takes place in the direction of the straight line in which the force acts.
Page 192 - Mercury will be represented by a grain of mustard seed, on the circumference of a circle 164 feet in diameter for its orbit; Venus a pea, on a circle 284 feet in diameter; the Earth also a pea, on a circle of 430 feet; Mars a rather large pin's head, on a circle of 654 feet...
Page 84 - If a number of forces acting at a point can be represented in magnitude and direction by the sides of a closed polygon taken...
Page 60 - If three forces, represented in magnitude and direction by the sides of a triangle, act on a point, they will keep it at rest.
Page 178 - This states that any two particles of matter attract one another with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Page 185 - ... 3. The squares of the periodic times of the various planets are proportional to the cubes of the major axes of their orbits.
Page 111 - A mass m is drawn up a smooth inclined plane, of height h and length I, by means of a string passing over the vertex of the plane, from the other end of which hangs a mass m'. Shew that, in order that m may just reach the top of the plane, m' must be detached after m has moved through a distance m + m
Page 271 - Ex. A Nicholson's Hydrometer when loaded with 200 grains in the upper pan sinks to the marked point in water ; a stone is placed in the upper pan and the weight required to sink it to the same point is 80 grains; the stone is then placed in the lower pan and the weight required is 128 grains; find the tp.
Page 175 - ... with the vertical. It is lowered by means of two ropes passing under the barrel, one end of each rope being fixed, while two men pay out the other ends of the ropes. What pull in Ibs. must each man exert in order that the barrel may be supported at any point ? (S.
