 Oil, made by the same firm, yielded for a coefficient of friction as the result of five different trials, .1246, .1195, .1297, .1201, .1221: mean, 1233. Much of the irregularity, slight as it is, is due to the variable speed of the engine. Concurrent...  Transactions - Page 421879Full view - About this book
