Moment of Inertia - Scalar Moment of Inertia of A Rigid Body

Scalar Moment of Inertia of A Rigid Body

In mechanics of machines, when designing rotary parts like gears, pulleys, shafts, couplings etc., which are used to transmit torques, the moment of inertia has to be considered. The moment of inertia is given about an axis and it depends on the shape and density of a rotating element.

When considering rotating systems like drive shafts, gear trains, and pulleys with more than one rotating element, more than one axis of rotation, an equivalent moment of inertia for the system can be found. The moment of inertia can be determined experimentally by measuring the angular acceleration for a known torque or it can be calculated from the masses and dimensions of the rotating elements and shafts.

Famous quotes containing the words body, rigid, moment and/or inertia:

    These was all nice pictures, I reckon, but I didn’t somehow seem to take to them, because if ever I was down a little, they always give me the fan-tods. Everybody was sorry she died, because she had laid out a lot more of these pictures to do, and a body could see by what she had done what they had lost. But I reckoned, that with her disposition, she was having a better time in the graveyard.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    I found a dimpled spider, fat and white,
    On a white heal-all, holding up a moth
    Like a white piece of rigid satin cloth—
    Assorted characters of death and blight
    Robert Frost (1874–1963)

    I don’t know Who—or what—put the question, I don’t know when it was put. I don’t even remember answering. But at some moment I did answer Yes to Someone—or Something—and from that hour I was certain that existence is meaningful and that, therefore, my life, in self-surrender, had a goal.
    Dag Hammarskjöld (1905–1961)

    What is wrong with priests and popes is that instead of being apostles and saints, they are nothing but empirics who say “I know” instead of “I am learning,” and pray for credulity and inertia as wise men pray for scepticism and activity.
    George Bernard Shaw (1856–1950)
