Homework Help: Why do we call the constant of proportionality in hook's law as Young's Modulus?

    Why do we call the constant of proportionality in hook's law as Young's Modulus and not as Young's coefficient? Is there any difference in Modulus and coefficient in engineering context?

    Hi perfectz! :smile:

    That's very interesting …

    I'll guess that a coefficient is a dimensionless ratio, between two things of the same type …

    for example, a coefficient of friction converts one force to another force …

    but a modulus changes (or modulates) a lengthy thing to a forcey thing. :redface:

    :rolleyes: now i expect people will start throwing counter-examples at me
