SHM Calculating Amplitude

  1. Mar 4, 2013 #1
    Hello and thanks for you time.

    Just a quicky :-)

    For a free vibration impulse response, the acceleration a is given by:

    a = -ω^2*Asin(ωt)

    So am I right in saying that you can rearrnage to calculate the amplitude A as:

    A = a/(-ω^2*sin(ωt))

    If the denominator is not zero, this is a valid transformation, sure.
    To calculate the amplitude in that way, you need all those parameters for some point in time.
