A Physics Oriented Mathematical Perspective for Creating Trochoids and Co-Centered Ellipses Based on Controlled Combination of Rolling and Sliding Motions
<|reference_start|>A Physics Oriented Mathematical Perspective for Creating Trochoids and Co-Centered Ellipses Based on Controlled Combination of Rolling and Sliding Motions: The mathematical perspective for creating trochoids [through a solid rule that is based on the pure rolling a circle along a straight line or another circle (centered trochoid)] is violated and changed it to a novel vision which is based on the combination of rolling and sliding motions of a circle along a straight line or another circle! In this new vision we have not to define a trochoid as a path that is swept by an attached point to a pure rolling circle along a straight line or another circle. Instead, a trochoid can be defined as a path that is swept by a definite point on the circumference of a rolling and sliding circle along a straight line or another circle! In this article we present two different methods for implement a definite combination of sliding and rolling motions for a circle along another one in order to make a simple experimental simulation to create centered trochoids and co-centered ellipses. In our novel mathematical vision not only, the physical concepts are playing basic role but also one can deduce the parametric equations of trochoids and ellipses on the bases of rolling and sliding motions. In this perspective, an ellipse can be visualized as a closed plane curve that can be generated through a definite combination of rolling and sliding motions due to two co-polarized rotational motions with different commensurable angular frequencies! Centered trochoids and ellipses can be implemented with the help of Virtual Rotating Circles Technique (VRCT) by an innovative device that we have named it Mechanical Oscilloscope (MO) and other trochoids by a Virtual Sliding Simulator (VSS). Although the functions of our devices are independent from other electronic equipment, but we can create trochoids on the bases of functional operation of (VSS) and (MO) with the help of computer.<|reference_end|>
