Questions
Which syllabus does the Theory of Machines course follow?
It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Theory of Machines. If your own university's syllabus differs, the centre follows your university syllabus.
Will this help in the university examination?
Yes. Teaching is unit-wise as per the AKTU scheme, with numericals, previous-year question practice, MCQ tests and doubt sessions before the semester exam.
Are graphical methods taught?
Yes. Velocity and acceleration diagrams, cam profiles and turning moment diagrams are drawn step by step on sheets.
