    Bullet Drag Flight
AI Thread Summary
The discussion focuses on the difficulty of finding accurate drag coefficient functions (G1, G2, etc.) for simulating a bullet's flight and calculating air resistance. The user is seeking a lookup table or calculator that provides exact drag coefficients at various Mach speeds. Several links were shared, including resources from Applied Ballistics, Wikipedia, and Hornady, but most lack the desired calculators or comprehensive tables. The user has employed various search terms related to bullet shapes and drag coefficients to find relevant information. The conversation highlights the challenge of accessing precise data for ballistic simulations.

I cannot seem to find them, and I am confused as to what they are. I am trying to simulate a bullet in flight and need to calculate air resistance. I'd like to be accurate to real life and use a lookup table but I can't seem to find a graph of the drag coefficients that has an accompanying calculator to calculate the exact numbers at each Mach speed.

What Google search terms have you been using? Can you post some links to pages that you have found that are at least close to what you are looking for?

Sure, here are things I've found:
https://appliedballisticsllc.com/wp.../Aerodynamic-Drag-Modeling-for-Ballistics.pdf
https://en.wikipedia.org/wiki/External_ballistics
http://dave2.freeshell.org/ammo/coeff8/coeff8.htm
https://kestrelmeters.com/pages/g1-g7-ballistic-coefficients-what-s-the-difference
https://en.wikipedia.org/wiki/Ballistic_coefficient

Most have information or a graph but not a calculator or table.
I've also been using search terms like:
- g1
- g7
- bullet shapes
- drag coefficient
- drag curve
- table
- calculator
 
I did a Google search on hornady bullet air resistance and this was the first hit. Does it help?

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...
