Point of mechanical engineering "balance"

**Lionelgee** · 4th February 2017, 03:04 PM

Hello All,

What is the point of balance called when something round and dynamic - such as a car tyre, is put into a "balancing machine" and weights are added to it until it is "balanced". Or in the case of a flywheel metal is removed until the fly wheel is balanced or runs "true". Other than "balanced" or "True" what is the term used in mechanical engineering parlance?

Is it the point of equilibrium? Or is it known by another name? For instance, in the example of a balance beam with two uneven weights located at opposing ends - a pivot can be repositioned under the beam until a point of equilibrium is reached and the beam is horizontal.

What is the term used when a disk is revolving from a central point and the disk is adjusted until it reaches a point of being in balance?

Thanks

Kind Regards
Lionel

I believe the technical term is:

'Not Wobbly"

'Balance' might just be the term

a dynamic balance or a centrifugal balance - my guess.

We just refer to it as balance at work

Hello All,

Thank you for your replies. I thought that there might be a longer physics based term for "balance".

I remember reading an article in an Australian motorbike magazine back in the 1980s. The article had an extensive written description and accompanying diagrams about what combination of forces - such as centrifugal force, plus about three other types of "forces", need to come together for a motorcycle to remain on two wheels while cornering.

There was some point where the forces came together to allow "balance" and forward momentum to continue while cornering. So two rotating disks moving forward while balanced. Go beyond that point of "balance" and things get dire very quickly.

P.S. Two Wheels Magazine ... plus Gyroscopic Force ...

Kind Regards
Lionel
