Questions
Are numerical problems covered?
Yes. Each unit has worked examples on velocity, belts, gears, governors and balancing at diploma level.
Are graphical methods taught?
Yes. Velocity diagrams and cam profiles are drawn step by step on drawing sheets.
Is this course based on the BTEUP syllabus?
Yes. The units follow the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus. If your polytechnic follows a different board or a revised scheme, the centre teaches your own syllabus.
