N2  - A unique interactive guide to understanding simple machines and mechanisms. Each spread introduces you to a key mechanical principle, for example levers, gears and pulleys. You then put these into practice by building working models using the perforated workshop board and colour-coded machine parts. A timeline on every spread explores how each machine has been used throughout history. With a hands-on approach that brings theories to life, this is a must for budding engineers.
