सवाल

Which syllabus does this course follow?

The NCVT / DGT CTS (NSQF) Workshop Calculation & Science syllabus for draughtsman trades, Year 2. The centre follows the student's own ITI syllabus where it differs.

Why do draughtsmen need beam and stress calculations?

They help in reading structural and machine drawings and in checking sizes, quantities and loads shown on them.

Are solved examples given?

Yes, every unit is taught with solved numericals followed by practice sheets.
