Weight of Sphere Covered in Piezo Force Sensors 3

[ConvexitySeller]

Hi all - new here and new to piezoelectric force sensing technology

I need to measure the weight of a sphere dropped onto a flat plane from a height of 1 foot.

[highlight #FCE94F](Im sure there is an easier way to do this - but please entertain my hypothesis)[/highlight][highlight #888A85][/highlight]

I want to cover the sphere in small circular piezoelectric force sensors so that ~99% of the surface area is covered. I will then drop the sphere and measure the resulting dynamic forces. After the initial impact force (and any forces incurred as the sphere rolls on the plane), could I effectively measure the weight of the sphere by measuring the final semi-static force of the sphere resting on the plane after it comes to a complete stop?

Sphere weight is anywhere between 50lbs and 250lbs

Dropping it from an approximate height is pointless and will not give you the weight. Very likely you will crush the sensors on impact.

If you can suspend the ball above the surface then just weigh it in the rig used to suspend it.

Thanks a ton for your replys and insight everyone. This is a hypothetical problem that answers a lot of questions I have about piezo sensors and my application. I now know what direction I need to move in my research. Its not for school - haven't been a student in some time. Thanks for your patience and the brainstorming - some super intelligent people here. Greglocock and Gruntguru especially - thanks for taking the time. I wish there was a PM function here. I may be back with more questions..

based on your question, i have no idea how we helpled you, 'cept maybe to undersstand how piezo-electric sensors work ...

another day in paradise, or is paradise one day closer ?

Some of us are also members of Link which does have a PM function.
