Sine wave load

      If I want to apply acceleration in a way of sine wave. Is this formula correct y = a* sin (omega t) [a = amplitude) or A = -(omega^2) A sin (omega  t) [A = acceleration) 

      Thanks in advance

      What are the units of y and a? Do you mean amplitude of the acceleration or the amplitude of the displacement? If the units of a and y are displacement then that is correct.

      What are the units of A? If the units of A are acceleration such as m/s^2 then that is also correct.

      You can apply the formula for y to a displacement boundary condition to create the desired acceleration.

        Sir, can you have a look at my queries once ?

        Thanks

      1) How can y and a have units of acceleration ? I mean its a formula of displacement, right? so why do we use in acceleration as well ?

      2) 'A' (second formula) is double derivative of 'y' -> will give 'Acceleration', right? So, woudn't be correct to use this formula for applying acceleration as sine load ?

      3)Applyin formula of 'y' to displacement boundary condition to create acceleration. Didn't get it properly, can you explain a bit, sir?

      writing queries in points so as to avoid any confusion. 

      Thanks
