In the vibrations example we worked through yesterday in class, on the D-axis of the graph, why does our plot intercept that axis at b/2? I may have copied something down wrong, but I'd just like to know how we determine where the graph intercepts that D axis.

It intersects the amplitude (D) axis at b/2.

If you take the amplitude equation we solved for, D = (3*k*b) / (-m*omega^2 + 6*k) and set omega equal to 0 (because you are looking for the y-intercept on the graph of omega v. amplitude), you will find that D = b/2
