Hey folks,
New to the forum and eager to tap the resources of all your brilliant minds.
Here's the problem. I'm modeling a system as a cylinder rotating on its end. Under a dynamic equilibrium situation with an applied force of a known value, I know its angular acceleration and instantaneous velocity.
How would one find the drag torque acting on the cylinder? I know the drag coefficient, area, and angular velocity of course, but need to apply it all to this drag force equation, Fd=-(1/2)*Cd*A*p*v^2,
where Cd is the drag coefficient, p the density of the medium (water in this case), and v the linear velocity.
Do you'll have a differential and derivative you can pull out of the air, something that accounts for the moment arm?
Many thanks!
