Simple Machines: The Inclined Plane Family (1959)

Discusses the use of inclined planes, a simple machine that has been utilized for centuries to make heavy lifting easier. Ancient Egyptians used inclined planes to construct pyramids by dragging heavy stones up sloping surfaces. The text includes an experiment demonstrating how inclined planes reduce the force needed to lift objects, while also requiring a longer distance to move them. It explains that while the total work remains constant, inclined planes make tasks easier by decreasing the force required. Various applications of inclined planes, such as wedges and screws, are also mentioned, highlighting their importance in everyday tasks.
