Page ix - Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.
Page ix - 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 force to change that state.
Page 114 - Guido, with a burnt stick in his hand, demonstrating on the smooth paving-stones of the path, that the square on the hypotenuse of a right-angled triangle is equal to the sum of the squares on the other two sides.
Page 1 - Feb. , 1903.) 24. Explain how to determine the relative velocity of two bodies. A is travelling due north at constant speed. When B is due west of A and at a distance of 21 miles from it, B starts travelling north-east with the same constant speed as A. Determine graphically, or otherwise, the least distance which B attains from A.
Page 95 - ... at 5 inches from the beginning of the stroke. 4. In a steam-engine the piston at the beginning of its stroke is exposed to a total pressure of 2000 Ibs., but the inertia is such that the thrust of the pistonrod at the cross-head is only 1600 Ibs. The speed of the engine is now raised until it becomes half as great again as before, while the pressure is unchanged : wj,at is the thrust of the piston-rod 1 [Inst.CEl 5.
Page 94 - What is meant by the instantaneous centre of a force moving in a fixed plane ? A rigid body has a plane motion. Three points on the body A, B, and C, in the same plane, are such that AB = 3 feet, BC = 2 feet, and AC = 2'6 feet. At a certain instant it is known that the point A has a velocity of 4 feet per second in the direction from A to C, and that the point B is moving in the direction from C to B. Show how the velocity of any other point on the body may be obtained, graphically or otherwise,...
