What is machine?

Machine

A machine is a powered tool consisting of one or more parts that is constructed to achieve a particular goal. Machines are usually powered by mechanical, chemical, thermal or electrical means, and are frequently motorized. Historically, a powered tool also required moving parts to classify as a machine; however, the advent of electronics technology has led to the development of powered tools without moving parts that are considered machines.

Famous quotes containing the word machine:

    I brush my hair,
    waiting in the pain machine for my bones to get hard,
    for the soft, soft bones that were laid apart
    and were screwed together. They will knit.
    And the other corpse, the fractured heart,
    I feed it piecemeal, little chalice. I’m good to it.
    Anne Sexton (1928–1974)

    Goodbye, boys; I’m under arrest. I may have to go to jail. I may not see you for a long time. Keep up the fight! Don’t surrender! Pay no attention to the injunction machine at Parkersburg. The Federal judge is a scab anyhow. While you starve he plays golf. While you serve humanity, he serves injunctions for the money powers.
    Mother Jones (1830–1930)

    The machine unmakes the man. Now that the machine is perfect, the engineer is nobody. Every new step in improving the engine restricts one more act of the engineer,—unteaches him.
    Ralph Waldo Emerson (1803–1882)
