OK, that's 180 degrees different!

• Do you have problems with programming?
• Do you have problems with the math?
• What have you tried?
• At what point did you get stuck?

How do I make it so the pendulum only goes 180 degrees instead of 360? So far I have managed to get a sin wave that's it

[altenbach]

Gravity will limit it to the lower two quadrants, assuming it starts there and the initial speed is zero. (If the initial speed is very high, it can go 360, of course.)

Hi Altenbach, (or anyone else who cares to help)

Do you have any clues why the dampening on my pendulum isn't working? I've attached my file below. Its using the idea that the formula for simple harmonic motion is x(t)=X*cos(w*t)+V/w*sin(w*t) and one of the equations for achieving dampening is Xdamped(t)=Xundamped*e^(-a*t) (where a would be the dampening coefficient).

Also, what's you best advice for a way to implement gravity into the top pendulum?

Stick it near a mass or some other constant Acceleration field.

Such a pedant.

I (and many others!) don't have LabVIEW 2021 yet, so please consider "save for previous" before attaching to widen the audience. (Most here cannot look at your VI and thus cannot tell what you are doing wrong.)

from the file that you posted above, what was the changes that you made?

Hi there so i have started a course assignment for a simple pendulum with damping but my pendulum length doesnt seem to stay the same length would greatly appreciate some help on the matter
