Drag force on a flat plat like a pendulum?

AI Thread Summary
The discussion focuses on calculating the drag force on a rectangular flat plate fixed like a pendulum, rotating around one end. Participants emphasize the need for a clearer understanding of the setup, suggesting that a sketch would help clarify the configuration. Reference is made to Hoerner's Fluid Dynamic Drag, which contains relevant experimental results. The conversation highlights the importance of detailed descriptions in fluid dynamics problems for accurate analysis. Overall, further information is required to provide a precise answer regarding the drag force.

Hi , please i want to know if i have flat plate (rectangle) but its fixed like pendulum (fixed from one end and free at the other end and can rotate around this fixed end) i want to know the drag force due to air on this plate?

Welcome to the PF.

So far, your description is not enough to understand the setup. Can you post a sketch please? You can use the Upload button in the lower right of the window to upload PDF and JPEG files.
 
You may find something of interest in Hoerner's Fluid Dynamic Drag. It is mostly experimental results from 1930s Germany.
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

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
