engineering quiz

[Carrie Moon]

Can you distinguish
Sinusoidal from
Harmonic Motion?

This is a quick physics refresher for the engineers. This information should be passed on to
non-engineers who may wonder about these important issues.


For Engineers:

 

[Carrie Moon]

For non-Engineers:


This is Sinusoidal Motion

 

[Carrie Moon]

This is harmonic motion

 

[shakenbake]

stay tuned

Harmonic motion?

 

[Carrie Moon]

this is a classic combination of
Sinusoidal & Harmonic Motion.

 

[shakenbake]

And sinusoidal motion! Are they critically damped?

 

[Carrie Moon]

Harmonic motion?

you're too quick for me! the point of stay tuned was give me 5 minutes to set the joke up.. I can't post another pic until a full 60 seconds has gone by...

The sinusoidal animation seems to be broken?

 

[Carrie Moon]

ha ha...
I thought you should keep abreast of these
classic mathematical and engineering problems.

 

[Carrie Moon]

The sinusoidal animation seems to be broken?

nope.. working fine on my screen.

And sinusoidal motion! Are they critically damped?

no because amplitude would tend towards 0 then.
