Questions

Which syllabus does the Materials Testing Lab course follow?

It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Materials Testing 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.

Which machines are used?

Universal Testing Machine, Brinell / Rockwell / Vickers hardness testers, impact tester, torsion machine and a metallurgical microscope.
