I'm not sure what a 'universitary' physics textbook is, but figuring out the moment on inertia of a complex mechanism, like a propeller, by calculation is generally avoided, unless there is already a numerical description of the blades, hub, etc. Most complex mechanisms have their moments of inertia determined experimentally, either by mounting the mechanism in a special pendulum and swinging it, or having it rotated by a known moment and measuring how long it takes to start or stop rotating.vinicius0197 said:Any basic universitary physics textbook would help you, I guess...
Sorry, I meant an 'university' physics texbook...SteamKing said:I'm not sure what a 'universitary' physics textbook is, but figuring out the moment on inertia of a complex mechanism, like a propeller, by calculation is generally avoided, unless there is already a numerical description of the blades, hub, etc. Most complex mechanisms have their moments of inertia determined experimentally, either by mounting the mechanism in a special pendulum and swinging it, or having it rotated by a known moment and measuring how long it takes to start or stop rotating.
A moment of inertia is a measure of an object's resistance to changes in its rotational motion. It is similar to mass in linear motion and is dependent on an object's mass distribution and shape.
The formula for moment of inertia is I = mr², where I is the moment of inertia, m is the mass of the object, and r is the distance between the object's axis of rotation and the mass element.
Moment of inertia is a measure of an object's rotational inertia, while mass is a measure of an object's resistance to changes in linear motion. Mass is a scalar quantity, while moment of inertia is a tensor quantity.
Moment of inertia is used in various engineering fields, such as designing car engines, calculating stress and strain on bridges, and determining the stability of aircraft. It is also used in sports, such as figure skating and gymnastics, to understand the movements and rotations of the human body.
There are several resources available for learning about moments of inertia, including textbooks, online tutorials, and educational videos. You can also consult with a physics or engineering professor, or visit a library to find books on the subject.
