Discussion Overview

The discussion centers on the significance of strain gauges and Wheatstone bridges, particularly in mechanical and robotics applications. Participants explore the relevance and functionality of these components, while also addressing the nature of the inquiry itself.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants note that strain gauges can be configured in a Wheatstone bridge topology, which can provide a differential output voltage that is independent of temperature.
  • There is a suggestion that strain gauges measure stress in robots, although this is presented humorously in the context of the discussion.
  • One participant questions the original poster's effort in researching the topic, asking for links to their reading and clarification on what is confusing them.
  • Another participant expresses skepticism about the inquiry being for fun rather than academic purposes, emphasizing the need for prior research before seeking assistance.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the significance of strain gauges and Wheatstone bridges, and there is contention regarding the appropriateness of the original poster's approach to seeking help.

Contextual Notes

Some participants express confusion about the original poster's understanding of the topic and the nature of their questions, indicating a lack of clarity in the inquiry itself.

Anyone know the significance of strain gauges and Wheatstone bridge in applications within mechanical and robotics areas. Thanks
 
Engineering news on Phys.org
An accurate strain gauge can be made from 4 strain elements in the topology of a Wheatstone bridge. The differential output voltage is then independent of temperature.
Your question needs to be more specific.

Sure, strain gauges measure how stressed robots are feeling. Wheatstone bridges are used by robots when making bread.

But seriously, (1) Have you done any reading about these questions at all? Post links to your reading and ask us about what is confusing you. (2) Is this a schoolwork question?

Ahaha funny guy you

But seriously, (1) Do you really think I would be asking you for help if I would have been able to find the information myself? Use your head mate (2) No, it's not school work I just ask these questions on physics forums for the fun of it.
 
Okay, I'll accept that it's not for school (so far), but you did not post links to your reading like I asked. Please do so, and tell us which parts are confusing you. There are indeed some confusing parts to understanding bridges, but until you show us what you have done so far, there is little we can do to help you.

1- Yes
2 - Presumably, sarcasm.

With luck you'll get all the help you deserve.

Brilliant words. Just what's needed if you really want help. And actually, a very apt reply back to you.
I wonder where you heard that PF is an alternative to doing your own spadework.
