It can indeed be used for any axis. But keep in mind that $I$ is a 3x3 matrix. Using different axes requires you to transform this matrix, so it corresponds to your set of choice. This can sometimes prove to be quite difficult as $I$ can be rather complex. The acceleration will always be in the direction of the total torque acting on your object. The moment ...

If you have a center of mass C located at $\vec{r}_C$ and a force $\vec{F}$ passing through an arbitrary point A (at $\vec{r}_A$) then the net moment of the force about C is $$\vec{M}_C = (\vec{r}_A-\vec{r}_C)\times \vec{F}$$ where × is the vector cross product. Your equations of motion sum up all the forces and moments at the center of mass  \sum_i ...

You more or less know the answer (but perhaps you need to rephrase your question). If the question is "for a given force vectors $\vec{F}$, when should I consider its effects on linear velocity $\vec{v}$ /linear acceleration $\vec{a}$? and when should I consider angular velocity $\vec{\omega}$ / angular acceleration $\vec{\alpha}$?" (1) If a force vector ...

This question of the causation of gyroscopic torque (and its magnitude and direction) troubled me all my life until I had a 'Eureka' moment about 20 years ago. I have written up the explanation of this phenomenon on my website, www.newtontime.com, using nothing more than Newton's Laws of Motion and without any need for 'fancy' mathematics. The analysis is ...

The moment of inertia is the rotational mass of the object and it is solely a function of mass distribution - the shape. Usually it does not matter if it is rotating, but if the rate of rotation is high enough the body could deform. This is a concern in the connecting rods of high speed engines. The MI does depend on shape, so it will change if the ...

Moment is bending due to linear force and the distance from the axis is perpendicular whereas in torque rotation takes place beyond 360 degrees.

A small shutting down on increasing resistance because the small generator has no ability to produce such current to perform such load. If the load is equal to the ability of the generator then it will not shut off.
