Some Studies About Spinning Mass

This book is based on the thesis entitled "Some Studies about Spinning Mass" submitted to Singhania University on September, 2014 for award of Ph.D. degree of the University. Text of this book is related to special relativity as well as general relativity. When an extended body moves with rectilinear motion it is understood that each part of the body is simultaneously affected by the same relativistic variations. However, in the case of curvilinear motion, different parts of the extended body experience different speeds and thus experience different relativistic variations. Such effects on mass, momentum etc. may be explained using complicated mathematics. In this work the relativistic effects on a rotating or spinning body is derived following a more classical approach. Now, photons contribute electromagnetic field that accompanies the gravitational field. These two fields may be mutually transformed through a kind of transformation matrix dependent upon the boundary conditions of the system. In this work trial has been made to find the nature of this transformation.
