Text-book of mechanics
A college engineering textbook on mechanics by Louis Adolphe Martin, published by John Wiley & Sons in New York in 1906 for students of applied mechanics and machine design. The illustrations are line diagrams of linkages, pulleys, cams and pivots, drawn with solid black bars, ringed pin joints, dashed construction lines, hatched fixed surfaces, and labelled force arrows and angle marks; useful as schematic linework, arrow and vector motifs, and lettered technical annotation.
