Hi, I have built an 8' long wind tunnel for use in an experiment to test the effects of turbulence on several variables. However, seeing as this is an educational-level/novice wind tunnel with a fan rating of ~1800 cfm the wind speeds only really go up to ~10 mph. From my understanding, this...

How would a strain gage be set up (on top of the model? around the sting?) to measure drag? I don't quite understand the connection between the force of drag and some sort of compression/tension force...? Thanks for the clarification.

Hello, Sorry if this seems like a very basic question to experienced engineers, but I'm a beginner in this area just looking to learn--- I thought up a research project, one of the components in which I need to generate ultrasonic waves. There were scrapped ultrasonic ring transducers (look...

Has anyone worked with piezoelectric materials before? Currently starting research work with them and totally new to these materials... I'm currently looking to buy CHEAP *non-toxic* piezoelectric PVDF and ceramics. Goodfellow seems to have PVDF, but paradoxically the website says it's a toxic...
