Description

Why is a spiral staircase easier to climb? How can a screw lift a heavy car? What is a propeller for? Screws have been sued for over 2,000 years as a simple machine that can make other machines work. When you turn a faucet on or off, ride on an airplane, or open a soda bottle you are using screws. This book explains what screws are and how they help you do everyday things. - from Amzon
