Σελίδα 421 - GEOMETRY. An Elementary Treatise on the Theory and Practice of Euclid. Having in view the New regulations of the Oxford and Cambridge Local, the London Matriculation, The Board of Education, and other Examinations. By SO ANDREW, MA, Head Master of Whitgift Grammar School, Croydpn.
Σελίδα 5 - The straight line or distance between the centres of the transverse lines in the two gold plugs in the bronze bar deposited in the Office of the Exchequer shall be the genuine standard of length ifc 00 at 62° F., and if lost it shall be replaced by means of its copies.
Σελίδα 396 - ... 5. A uniform chain 6 feet long, having a mass of 2 pounds per foot, is laid in a straight line along a rough horizontal table, for which the coefficient of friction is {, a portion hanging over the edge of the table so that slipping is just about to occur. If a slight disturbance sets the chain slipping, find the tension at the edge of the table when x feet have slipped off. 6. Two equal balls A, B, each of mass m, are at a distance a apart.
Σελίδα 381 - ... other, they are inversely as the perpendiculars drawn from the fulcrum to the directions in which the forces act. Describe the Balance known as the bent-lever Balance, (in which the weight (P) is always the same), and shew how to graduate it. 3. If three forces, represented in direction and magnitude by the sides of a triangle taken in order, act on a point, they will produce equilibrium. Two forces, whose magnitudes are «/3xP, and P, respectively act at a point in directions at right angles...
Σελίδα 78 - ... the angle subtended at the centre of a circle by an arc equal in length to the radius, therefore 2ir radians = 360 degrees.
Σελίδα 422 - ... KNOWLEDGE OF NATURAL HISTORY, BOTANY, PHYSIOLOGY, PHYSICS AND CHEMISTRY FOR YOUNG PEOPLE. By Mrs. W. AWDRY (Wife of the Bishop of South Tokyo, Japan). Edited by WF BARRETT, FRS, Professor of Experimental Physics in the Royal College of Science for Ireland. With nearly 200 Illustrations. Crown 8vo. 6s. " Deserves a warm welcome from all teachers of the young. . . . The illustrations are models of clear, careful, and unconventional work.
Σελίδα 385 - Where will the bullet strike the ground ? 2. A rifle bullet, fired horizontally at a height of 10 feet above the surface of a lake, strikes the water at a distance of 500 yards. Find its velocity in feet per second, the resistance of the air being supposed negligible. 3. Prove that the claim for a rifle, that the bullet does not rise more than one inch in a range of 100 yards, implies that the velocity must be greater than 2078 feet per second. 5. A shot fired from a gun whose muzzle is close to...
Σελίδα 386 - Prove that the shortest time from rest to rest in which a chain which can bear a steady load of P tons wt. can lift or lower a weight of W tons through a vertical distance of h ft. is -P~ ~ secs- [LoND-] 2.
