Questions

Which syllabus does the Theory of Machines Lab course follow?

It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Theory of Machines Lab. If your own university's syllabus differs, the centre follows your university syllabus.

Will this help in the university examination?

Yes. Experiments are explained with aim, theory, procedure, observation table, calculation and viva questions, so you can write the lab file and face the practical exam confidently.

Is the governor experiment dangerous?

The rig runs at speed, so students work with guards on and under trainer supervision; safety rules are explained first.
