Сторінка 27 - 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.
Сторінка 51 - If any number of forces, acting on a particle, be represented, in magnitude and direction, by the sides of a polygon, taken in order, the forces shall be in equilibrium.
Сторінка 68 - The moment of a force about a point is the product of the magnitude of the force by the perpendicular distance from the point to the line of action of the force.
Сторінка 139 - A balloon is carried along by a current of air moving from east to west at the rate of 60 miles an hour, having no motion of its own through the air, and a feather is dropped from the balloon. What sort of a path will it appear to describe, as seen by a man in the balloon?— (Matric., June 1874.) CHAPTER II.
Сторінка 33 - 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 distance from each other.
Сторінка 8 - If three forces, acting at a point, can be represented in magnitude and direction by the sides of a triangle, taken in order, they will be in equilibrium.
Сторінка 72 - Prove that the algebraic sum of the moments of two concurrent forces about any point in their plane is equal to the moment of their resultant about the same point.
Сторінка 42 - The work done by a force acting obliquely on a mooing body is measured by the product of the force and the distance through which the body moves in the direction of the force.
Сторінка 31 - Change of motion is proportional to the impressed force and takes place in the direction of the straight line in which the force acts.
Сторінка 140 - Draw carefully a system of pulleys in which each pulley hangs by a separate string and the ratio of the power to the weight is 1 to 32.
