What is the formula for calculating drag coefficient?

AI Thread Summary
The drag coefficient (Cd) can be calculated using the formula Cd = 2D / (ρv²A), where D is the drag force, ρ is the fluid density, v is the velocity of the object relative to the fluid, and A is the reference area. The discussion highlights the difficulty in finding clear information on this topic, with users expressing frustration over the overwhelming amount of content available. A user seeks a straightforward explanation and appreciates any assistance provided. The conversation emphasizes the importance of understanding the drag coefficient for various applications. Clear guidance on this formula is essential for those looking to grasp aerodynamic principles.

Drag coefficient formula?

What is the formula for finding this out? Sorry, for being n00bish and for this not being posted in the relevant forum but this one has the most people viewing so I thought I'd get the quickest response this way. Thanks.

O yea, I've tried searching, but sifting through the pages of posts makes mine eyes hurt. plus, i didnt find too much either...anyways, help is appreciated.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
