Theory of Machines Mcqs

This set of Mechanical engineering Multiple Choice Questions & Answers (MCQs) focuses on study of “ Theory of Machines ”. These questions are chosen from a collection of most authoritative and best reference books on Mechanical engineering. Our aim is to prepare an individual for competitive exams like NTS, GAT, ECAT, University and College entrance exams, Jobs and interviews. One should practice our MCQS to assimilate Theory of Machines comprehensively.
