Drag Measure Strain Wind Wind tunnel

AI Thread Summary

A strain gage can be effectively set up on the sting or the model itself to measure drag in a wind tunnel. Drag is a force that opposes an object's motion through a fluid, resulting from pressure differences and friction. The connection between drag and strain gages lies in the measurement of deformation caused by drag forces, which can be interpreted as tension or compression. Understanding drag involves considering the principles of fluid dynamics and how forces act on surfaces. Proper setup and calibration of the strain gage are crucial for accurate drag measurement.

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.

Consider: what is drag? Where does it come from?

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
