Because when I create ONE curve by taking the peaks, then get its equation (which is an exponential y=a*(e^(b*x)) ) -using excel- and then ANOTHER by taking the troughs (multiplying by -1 to make it positive), then writing its equation (which is an exponential also)... When I compare the...

Hello! I have data of a damped oscillation (the movement on Y as it dies down in time). Imagine for example a ball that is hanging from a spring and it keeps bouncing up and down under the spring until it stops. The problem is I do not know how to find the axis around which the oscillation...

Yes I know, but I didnt have anymore time left.. :(

Ok, i did it by mirroring the chart on paper. Wasnt that precise, but it worked. Thank you all for your time and I am sorry for the disturbance..

Thank you, Ill try to do that...

1. Homework Statement If you could please tell me the "fall" laws for displacement, velocity and acceleration for a cam with constant acceleration. 3. The Attempt at a Solution Could only manage to find the laws for the rising part, in a 1996 book. Didnt find the laws on google...

Thank you very much for your reply!:) Yes, you are right that the fall is opposite to the rise, but I don't know how to "mirror" the laws. For ex: Displacement: Xe= (Xemax/((1-ki)*(Xi)1^2))*(-ki*(Xi)1^2+2*(Xi)1*Xi-Xi^2) Xe=movement[rad], Xemax=max value for Xe [rad], Xi=current...
