Questions
Which syllabus does the Strength of Materials course follow?
It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Strength of Materials. 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 numericals covered in detail?
Yes. Every unit has solved numericals from AKTU previous papers and a practice sheet with answers.
