Σελίδα 235 - SOLDERS. For Lead. — Melt one part of block tin, and, when in a state of fusion, add 2 parts of lead. Resin should be used with this solder. For Tin. — Pewter, 4 parts ; tin, 1 ; bismuth, 1. Melt them together and run them into slips.
Σελίδα 38 - RULE. — To the sum of the areas of the two ends add the square root of their product ; multiply this sum by the perpendicular height, and -^ of the product is the solid content.
Σελίδα 128 - Bring the edges of the pieces of shell to fit each other, observing to give the same inclination of grain to each, then secure them in a piece of paper, and place them between hot irons or pincers ; apply pressure, and let them cool.
Σελίδα 65 - RULE. — Divide the weight to be raised by twice the number of pulleys in the lower block ; the quotient will give the power necessary to raise the weight. EXAMPLE. — What power is required to raise 600 Ibs., when the lower block contains six pulleys ? 600 6 x 2 = 50 Iks., Ans.
Σελίδα 53 - To find the centre of Gyration, multiply the weight of the several particles by the squares of their distances from the centre of motion, and divide the sum of the products by the weight of the whole mass; the square root of the quotient will be the distance of the centre of gyration, from the centre of motion.
