Term
Amber
Definition
A hard yellowish partly transparent resin form trees long dead that can be highly polished and is used for ornamental objects (as beads).
Term
Simple Machines
Definition
Usually the term refers to the six classical simple machines which were defined by Renaissance scientists:
Lever
Wheel and axle
Pulley
Inclined plane
Wedge
Screw
These simple machines fall into two classes: (i) the inclined plane, wedge, screw characterized by the vector resolution of forces and movement along a line, and (ii) the lever, pulley, wheel and axle characterized by the equilibrium of torques and movement around a pivot.
A simple machine is an elementary device that has a specific movement (often called a mechanism), which can be combined with other devices and movements to form a machine. The view of machines as decomposable into simple machines arose in the Renaissance as an interpretation of Greek texts on technology.
Simple machines are considered to be the "building blocks" of more complicated machines. For example, wheels, levers, and pulleys are all used in the mechanism of a bicycle.
