Tool vs. Machine

Machine A machine is any mechanical or

organic device that transmits or modifies energy to perform or assist in the performance of tasks. (energy in for work out) (Wikipedia)

Components of a Machine: Combination of the 5 basic tools

The Early Tools

Prehistory of Mechanics 5 primary machines

Lever Wedge Screw Pulley Inclined Plane

Wheel and Axle

Page 8: Tools and Machines Prehistory Takeover throughout the 18 th Century 19 th Century Julie Johnson

The Early Tools - Lever

Lever is made of 3 parts: the weight, fulcrum, and power point. 3 types of levers based on where the 3

components are

Earliest form of the lever is the digging stick

Page 9: Tools and Machines Prehistory Takeover throughout the 18 th Century 19 th Century Julie Johnson

The Early Tools - Wedge

A wedge is used to separate two objects, or portions of objects, through the application of force, perpendicular to the inclined surfaces.

Used for splitting trees, breaking masses of ore, lifting weights, and hafting stone tools

Examples –knives, axes, nails, looms

Page 10: Tools and Machines Prehistory Takeover throughout the 18 th Century 19 th Century Julie Johnson

The Early Tools – Inclined Plane

The inclined plane permits one to overcome a large resistance by applying a relatively small force through a longer distance than the load is to be raised.

Since women were the burden bearers they are more likely to have invented the inclined plane

Page 11: Tools and Machines Prehistory Takeover throughout the 18 th Century 19 th Century Julie Johnson

The Early Tools - Screw

A screw is used to translate torque into linear force. It can also be defined as an inclined plane wrapped around a shaft.

Mayan culture has a screw-top ceramic jar Pottery making was predominantly or exclusively

women’s work in 80 out of 105 societies

Page 12: Tools and Machines Prehistory Takeover throughout the 18 th Century 19 th Century Julie Johnson

The Early Tools - Pulley

Pulleys are usually used in sets designed to reduce the amount of force needed to lift a load.

Amount of work is the same with or without pulleys Vertically or horizontally “dead-eye” pulley used rope wrapped

around a tree

Wheel and Axle

Rotary Motion Replaced back and forth motion

Fly-wheel Sister Tabitha Babbitt

Invented the circular saw in 1810

Page 14: Tools and Machines Prehistory Takeover throughout the 18 th Century 19 th Century Julie Johnson

Wheel and Axle

Sindhi women and the rotary churn Meso-American culture Rollers

Women Eskimos Malta’s Temples

Page 15: Tools and Machines Prehistory Takeover throughout the 18 th Century 19 th Century Julie Johnson

Primate Ethology

Chimps used natural hammers when cracking nuts in Ivory Coast, Africa Coula nut: easily use a rock on the

ground or eat in the “food tree” Hard-shelled Panda nut

Equal number ate the easy way Very few male chimps ate in the trees

or ate the Panda nut.
