Questions
Which syllabus does the Machine Design-I course follow?
It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Machine Design-I. 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.
Is a design data book needed?
Yes. Keep a design data book (PSG or as allowed by your university); we teach how to pick values from it during numericals.
