Harmonic Motion-trig
Here's the question:
The motion of a piston is harmonic. Suppose that a piston's length is 8 inches. When it is moving at 4500 rpm (revolutions per minute), the model for its motion will be H=Asin(Bt) It wants to know what A and B are I found the answer for B to be 28274.33 because B=2pi * T or B=2pi * 4500 Now I don't know how to find A (amplitude).. is there a formula I'm supposed to use? Please help.. its due at midnight.. I know.. short notice.. but I do appreciate any help or advice. Thanks |
