Strain Gauge and Wheatstone Bridge Introduction 

Best short explanation of Wheat bridge ever. Great job!

Best explanation i've heard for the Wheatstone bridge. Thanks

*PLZ HELP*. Given a pressure of 2kpa, nominal resistance of 120 ohm, diameter of strain gauge 0.1mm, a GF of 2. What will be the change in resistance value of the strain gauge?....in short I wanta formula to calculate the change in resistance of strain gauge for a given INPUT PRESSURE

Thank you, sir! Please keep them coming. Simple and elegant.

So far, best explanation of how a strain gauge and its signal actually behave, with orders of magnitude (very important and rarely given in online courses), that helped me checking my results. Thanks a lot !

YOU ARE BRILLIANT- THANK YOU SOOOOOO MUCH

poissons ratio formula is correct by laterally its area thats is changing but not the length so it shud be da / dl

this really helps. (I am going to install a strain gauge on a vertically installed metal plates while the plates are being shaken by vibration exciter , which make things more difficult . if u can suggest specific strain gauge it would be appreciated ) thank you so much

Well explained. Thank you so much.

Thanks Rick

good explanation. thanks...
