JNTUK R23 B.Tech Mechanical III Year I Semester (3-1) Syllabus & Subject-wise Topics

Total: 15-0-10, 23 credits.

Also offered as optional add-ons outside the core total: a Minor Course from the specialization-minors pool (3-0-3, 4.5 credits), a Minor Course via SWAYAM/NPTEL (3-0-0, 3 credits), and two Honors Courses from the honors pool (3-0-0, 3 credits each). These minor/honors slots are drawn from a separate elective pool spanning many possible named subjects rather than one fixed syllabus, so they are not expanded subject-by-subject here.
