Calculating S Using Fm in a Magnus Force Equation

Click For Summary
SUMMARY

The discussion focuses on calculating the air resistance coefficient (S) in the Magnus force equation, represented as Fm = S (w × v). Here, Fm is the Magnus force vector, w is the angular velocity vector, and v is the velocity of the fluid or object. Participants emphasize the importance of rearranging the equation to isolate S for accurate calculations. Understanding the relationship between these variables is crucial for applications involving the Magnus effect.

what is s in this equation and how what equation do I need to figure out what S is
Fm = S (w × v)

Where:
Fm =the Magnus force vector

w= angular velocity vector of the object

v=Velocity of the fluid (or velocity of object, depends on perspective)

S= air resistance coefficient across the surface of the object

learn to rearrange the subject of the equation to S.
The magnus effect might be because of inertia.
