This chapter presents an alternative to the Euler rotation formula, a formula that returns the rotation matrix as a function of any given axis and rotation angle. But the method used is extendable in the most surprising directions, and with the most profound consequences for symmetries in physics...
For those who haven't heard the word, "precession" is when an object with a nonspherical shape wobbles around its rotation axis. The animation programs of the making revolution surface is compiled, and a general coordinate formula of geometric transformation is deduced about an arbitrary revolution...
Parallel Axis Theorem Formula Questions: 1) A solid sphere with mass 60.0 kg and radius 0.150 m has a moment of inertia for rotation through its central axis. What will be the moment of inertia of the sphere, if the rotation axis is changed to pass through a point on its surface? Answe...

The aim of this paper is to give a new deduction of Rodrigues' rotation formula. An other benefit of the this deduction is to give a transformation matrix of reflection through an arbitrary plane with the same deduction method. In our opinion this deduction method is better for students, who...
A semi-empirical method involving asymptotic expansions is used to obtain an approximate formula for the fundamental frequency of a uniform rotating beam clamped off the axis of rotation. Results from the formula are shown to be of the order of 0·1% different length. Thus, the designer is pro...
Using this notation and (3.3.21), we find from expansion (3.3.17) the following formula for spherical basis function rotation transform: (3.3.23)Fnm(r)=∑m′=−nnTnm′m(Q)Fnm′(r^),n=0,1,2,…, m=−n,…n, F=S,R. This reveals several interesting facts. First, ...
