How to divide pressure applied at a point on a rod?

Click For Summary

Discussion Overview

The discussion revolves around how pressure applied at a specific point on a rod can be equally distributed underneath the rod. Participants explore the implications of material choice, the configuration of the rod, and the context of its application, particularly in relation to piezoelectric systems under roadways.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants inquire about the shape and alignment of the rod, suggesting that these factors are crucial for understanding how pressure distribution occurs.
  • One participant mentions using an aluminum sheet for piezoelectric applications, indicating that pressure from vehicles needs to be evenly distributed across the road.
  • Concerns are raised about the lack of detail in the original question, with requests for specifics regarding the road material, the thickness of the aluminum sheet, and its dimensions.
  • Some participants express skepticism about the feasibility of the proposed setup, questioning whether a pressure plate placed four feet beneath the road would effectively sense pressure from vehicles.
  • There are suggestions that the original poster may not have sufficient engineering knowledge to tackle the problem, with calls for involving an experienced engineer.

Areas of Agreement / Disagreement

Participants generally agree that the original question lacks sufficient detail and clarity. Multiple competing views remain regarding the feasibility and design considerations necessary for effectively distributing pressure in the described scenario.

Contextual Notes

Limitations include missing assumptions about the road material, the thickness and size of the aluminum sheet, and the specific conditions under which the pressure is applied. These factors remain unresolved in the discussion.

Hello Every one
I want to know how the pressure applied at a particular point on a rod will be equally divided underneath of the rod. What materials are good to achieve this kind of situation?

This is a very vague question. You need to specify more. What is the shape of the rod? How is it aligned with whatever it is sitting on (is it on its side? on its end? what?).

Do you mean like a beam bending from a force pushing down on top? Could you please provide much more detail -- your question is too short and vague for us to be able to help...

Hello
Here i am using an aluminum sheet. This is done for piezo electricity, It is placed underneath the road and when the vechiles passed by the road the pressure acts at a particular point on the sheet and we have to divide that pressure equally to the entire road

You have not provided NEARLY enough information to give any meaningful answer. What is the road made of? How far "under" the road is the sheet? how thick is the sheet? The list just goes on and on. Clearly you are not an engineer or you would have realized that such things need to be specified and since you are not an engineer, I don't understand why you are involved in designing this or how you can possibly expect to do it.

hello

The sheet is made of aluminium and placed 4 feet underneath the road, it is placed underneath highway roads

Do u still need more information ??

Uh ... do you think maybe it matters if the road is concrete or macadam? How about how thick the sheet is? How BIG is the sheet? Do you expect two tires at a time to press on the sheet or just one?

I could go on but I don't think you are getting the point. Besides, at four feet under the road I don't even see how your pressure plate will feel much of anything. I say again, I think you need to get an experience engineer involved in this and I DON'T mean by asking questions on an internet forum as you are doing now.

Look, I'm not trying to give you a hard time on this, I just think you are in WAY over your head.

The OP's question is somewhat cryptic and I hope the idea behind this would not be to weaponize something.
