About the Karnataka SSLC Elements of Mechanical Engineering IV — JTS (KSEAB) Exam
Karnataka SSLC Elements of Mechanical Engineering IV is the Class 10 Junior Technical School (JTS) mechanical theory subject under the Karnataka School Examination and Assessment Board (KSEAB, formerly KSEEB), paper code 52 / 52E. It assesses foundational mechanical engineering knowledge: engineering materials and properties, heat treatment, casting, welding, machine tools and machining, belt and gear power transmission (including gear-ratio and efficiency calculations), IC engine basics, pumps and compressors, simple thermodynamics, measuring instruments, fasteners, workshop safety, and simple stress. Official assessment combines written theory with practical workshop and oral components for JTS students — it is not pure MCQ. Fees and exact blueprints are notified by KSEAB on kseab.karnataka.gov.in; pass marks are commonly described as about 30–33% per subject with aggregate rules. The 100 questions on this page are a free English-language multiple-choice theory study adaptation; they are not a substitute for practical/oral assessment or a full simulation of the official mixed paper.

Frequently Asked Questions
Is the official KSEAB SSLC JTS Elements of Mechanical Engineering IV exam pure multiple-choice?
No. Official KSEAB SSLC JTS Elements of Mechanical Engineering IV (52 / 52E) combines written theory (mixed objective and subjective items as in board model and public papers) with practical workshop skill assessment and oral examination for JTS students. This bank is an English-language multiple-choice theory study adaptation only — not a practical/oral substitute or official paper simulation.
What is paper code 52E?
52 / 52E is the KSEAB SSLC JTS subject code used on board model and public examination listings for Elements of Mechanical Engineering-IV (English-medium coding as published on the board portals).
Does this practice set replace the practical or oral exam?
No. Practical and oral components measure hands-on workshop competence and spoken technical understanding. MCQs here only reinforce theory and calculation knowledge. You must still complete school practicals/orals and follow KSEAB JTS schedules.
What topics are covered in KSEAB SSLC JTS Elements of Mechanical Engineering IV theory?
Typical Class 10 JTS mechanical content includes engineering materials and properties, heat treatment, casting, welding, machine tools, power transmission (belts/gears), IC engines, pumps/compressors, simple thermodynamics, measuring instruments, fasteners, and workshop safety — with simple calculations such as gear ratio, efficiency, and tensile stress.
What is the passing score for this subject?
SSLC-consistent reporting commonly describes about 30–33% in each subject together with overall aggregate rules as notified by KSEAB. JTS subjects also require meeting practical/oral expectations set by the school and board. Verify the current result/pass criteria circular for your examination year.
