Machine Elements

Machine elements covers the knowledge needed to correctly select, calculate, and draw the standard parts that form the foundation of every machine. In this category you’ll find explanations covering a wide range, from fastening elements like screw types, metric and Whitworth thread systems, and pipe threads, to small but critical parts like washers, cotter pins, and retaining rings. Fundamental topics such as cam mechanisms and dimensional tolerances are also explained with annotated example illustrations, in Q&A format, and with standard measurement tables. A student new to the machine elements course can learn step by step here why a part is designed the way it is and where it’s used. It’s also a practical reference for engineers working in the shop who need to quickly look up the right cotter pin size or the correct tolerance value.
