Book Title: Strength of Materials
Author: Er. R.K. Rajput
Printed Price: INR 850.00
This book contains almost all the concepts relating to Strength of Materials and is written by Er. R K Rajput. Information about Aurthor is given in the back cover of the book and with reference to that information the following is gathered about him:
He was born on September 15, 1944(Before independence and co-incidental with Engineer's Day). He is a Master of mechanical Engineering(with hon. and Gold Medal) from Thapar Institute of Engineering and TEchnology from Patiala. Also he is graduate in Electrical Engineering.
He has more than 40 years of experience of teaching the subjects in Mechanical and Electrical Engg. He has earned following awards:
1) Best Teacher(Academics) Awards
2) "Distinguished author award"
3) Jawahar Lal Nehru Memorial Gold Medal for outstanding research paper.
Here is an excerpt from the book, you can see for yourself the wisdom and knowledge contained by the book:
Unsymmetrical Bending and Shear CentreIntroduction:
In chapter on Bending Stresses, while using the well known equation M/I = f/y, it is assumed that the neutral axis of the cross section of the beam is perpendicular to the plane of loading. This condition implies that the plane of loading or plane of bending is co-incidental with, or parallel to, a plane containing a principal centroidal axis of inertia of the cross section of the beam. If, however, the plane of loading or that of bending, does not lie in(or parallel) to a plane that contains the principal centroidal axis of the cross-section, the bending is called unsymmetrical bending.
In unsymmetrical bending, the direction of neutral axis is not perpendicular to the plane of bending. Following are the two reasons of unsymmetrical bending:
(1) The section is symmetrical(viz. rectangular, circular, I sections) but the load line is inclined to both the principal axes.
(2) The section itself is unsymmetrical (viz. angle section or channel section vertical web) and the load line is along any centroidal axis.
Beside whole the syllabus covered in the book chapter no. 23 titled "Universities' Questions(REcent) - with solutions" has been added in this 5th edition of the book so as to make it more useful.
