The Advanced Course On The Subject For The Students Of Mechanical And Civil Engg. Disciplines. This Book Will Act As A Faith Full Companion To The Students Studying A Course On Machine Design And Computing Stresses In Machine Members And To Engineers Serving In Design Offices Of Various Research And Development Organisations.
The Author Is Teaching The Subject For The Last 23 Years And Is Fully Conversent With The Difficulties Experienced By The Students. Therefore, While Preparing The Text Of The Book, The Point Of View Of The Students Was Constantly Kept In Mind. The Contents Of The Book Have Been Designed In A Manner To Help All Grades Of The Students.

The Advanced Chapters On Bending Of Curved Bars, Rotational Stresses, Energy Methods, Unsymmetrical Bending, Shear Centre And Torsion Of Non Circular Shafts Are No Doubt Avail- Able In Many Books But Either The Treatment Given Is Too Elementary Or The Examples Given Are Insufficient. As A Result, The Students Are Apprehensive Of These Chapters When They Appear In The Examinations. Therefore, These Topics Have Been Thoroughly Explained And A Large Number Of Solved Examples Are Given So That The Students Can Very Well Understand These Advanced Topics. Constructive Suggestions For Improvement Of The Book Are Always Solicited.
