Lifting by Levers (How Things Work)
By Andrew Dunn.
Description
Each title in this series takes one simple scientific principle as a basis for explaining the workings of a selection of everyday gadgets and machines. The illustrations aim to de-mystify the scientific theory and expose the workings of each machine. Focusing on levers, this book describes such terms as fulcrum, effort and load, and sets out to show how levers are used in a multitude of everyday machines, from a simple spade to a grand piano and a seesaw to a typewriter. - from Amzon
