Side ii - A Pocketbook of Electrical Rules and Tables for the use of Electricians and Engineers.
Side 249 - Hence the general rule, the strength, of rectangular beams to resist bending is directly proportional to the breadth, to the square of the depth, and inversely proportional to the length of the beam.
Side 86 - angle of friction." Therefore, the tangent of the angle of repose is equal to the coefficient of friction. p But — was proved by the previous experiment to be also equal to the co-efficient of friction...

Side 115 - Wheel.) 3. What is the pitch of a tooth in a spur wheel ? Two parallel shafts, whose axes are to be as nearly as possible 2 feet 6 inches apart, are to be connected by a pair of spur wheels, so that while the driver runs at 100 revolutions per minute, the follower is required to run at only 25 revolutions per minute. Sketch the arrangement, and mark on each wheel its diameter and the number of teeth, supposing the pitch of a tooth to be ij inch. (S. and A. Exam. 1890.) Ans. The follower is 48 inches...
Side 123 - Ibs. 6. In a crane there is a train of wheelwork, the first pinion being driven by a lever handle ; and the last wheel being on the same axis as the chain barrel of the crane. The wheelwork consists of a pinion of 1 1 gearing with a wheel of 92, and of a pinion of 12 gearing with a wheel of 72, the diameter of the barrel being 18 inches and that of the circle described by the end of the lever handle being 36 inches ; find the ratio of the pull to the weight raised, friction being neglected.
Side 2 - The unit of force is that force which, acting for one second on a mass of one gramme, gives to it a velocity of one centimetre per second.
Side 93 - Ans. 6,900 ft.-lbs. ; 2,900 ft.-lbs. ; /u= _ = — = -204. 6 12 6. What is the co-efficient of friction, and how is it ascertained? There is an inclined plane of I foot vertical to 5 feet horizontal ; what work is done in moving 100 Ibs. through 100 feet along the plane, the co-efficient of friction being...
Side 15 - If the moments of those forces which tend to turn the body to the right hand (ie, in the direction of the motion of the hands of a clock) be called positive ( + ), and the moments of the remaining set of forces which tend to turn the body to the left hand (ie, in the opposite direction to the movement of the hands of a clock) be called negative ( — ), then the algebraical sum of the moments of the forces which act in one plane, and which are in equilibrium about a point, is zero.
