If you want to be an engineer you will have to have a grasp of the basics!

I pity the non-engineers who cannot discern the sinusoidal motion on the part of the subject. Us engineers, on the other hand, take delight in burying ourselves in such interesting research.

Describing simple harmonic movement.

2) For non-engineering types:

I hope this has been a valuable lesson you will remember for the rest of your life!

i don't see anything....

probably my work computer...

Jason, I just added them as attachments so you can use the reference material.

sweet!

HUH, what's that Jason??????

You say there's an equasion???????????

WHAT EQUASION????????????????

(Good grief, .......my eyeballs are STILL bouncing).

I'm a mechanical engineering student. I think after this lesson in sinusoidal motion, you might want to talk about damped oscillation, because that has to do with car suspension. The spring wants to continually oscillate, but the shock is used to create "critically damped" motion. Just a thought.

In this case, Pennyman, the dampening system for the oscillation is simple. Place a carbon-based metacarpus (preferably two) against the oscillating object(s) and the shock will severly dampen.

When those two carbon based objects start to sag, you will need to add some silicone to restore them to close to OEM specs.

I'm no engineer, but I am familiar with oscillations and I like them. Now, you need to apply some positive torque to those oscillations and study the affects.:cheeky:
