Definition: This calculator determines the aerodynamic torque (\( \tau \)) on a football based on its velocity, distance from the Center of Pressure (CoP) to the Center of Mass (CoM), angle of force, drag coefficient, and radius.
Purpose: It assists engineers, physicists, and sports scientists in analyzing the rotational effects of air resistance on a football.
The calculator uses the relationship:
Where:
Explanation: Enter velocity, distance, angle (0-180°), drag coefficient, and radius, and the calculator computes torque in N·m and N·in.
Details: Aerodynamic torque affects the spin and stability of a football, influencing its trajectory in sports and aerodynamics studies.
Tips: Enter positive values for velocity, distance, angle (0-180°), drag coefficient, and radius, then click "Calculate." Results show torque in N·m and N·in (to 5 decimal places, or scientific notation if less than 0.0001).
