How do you find the torque and angular of a variable center of mass object that is rotating vertically just as a windmill?

Answer 1

To find the torque of a variable center of mass object like a vertical windmill, first identify the forces acting on it, including gravitational and aerodynamic forces. Calculate the torque ((\tau)) using the formula (\tau = r \times F), where (r) is the distance from the pivot point to the center of mass and (F) is the force applied. The angular acceleration ((\alpha)) can be derived from Newton's second law for rotation, (\tau = I \alpha), where (I) is the moment of inertia about the pivot point. Adjust the moment of inertia as the center of mass changes to obtain accurate results.
