However, student may be asked to attempt only 1 question from each unit. No.1 rest of the paper shall consist of four units as per the syllabus, every unit should have two questions. This question should have objective or short answer type questions. 1 should be compulsory and cover the entire syllabus. INSTRUCTIONS TO PAPER SETTERS: MAXIMUM MARKS: 75 Paper: Strength of Materials & Theory of Machines 3 1 4 Unsolved end-of chapter exercises.STRENGTH OF MATERIALS & THEORY OF MACHINES A large number of solved examples, short answer type questions chaper wise. This has been reinforced by a large number of solved examples. The subject matter has been explained in the simplest possible way for easy assimilation by the students. The book has been written as per the new syllabus of these Universities. students of UP technical University, Lucjnow and Uttrakhand technical University, Dehradun.
