Maharashtra SSC Mechanical Technology Pre-Voc/NSQF study guide
Maharashtra SSC Mechanical Technology Pre-Voc/NSQF · Work through your exam, one topic at a time.
Mechanical Technology is an NSQF-aligned vocational subject offered at the SSC (Class 10) level under the Maharashtra State Board of Secondary and Higher Secondary Education. It is a pre-vocational subject: instead of a purely academic elective, students study trade-related theory and do workshop-based practical work, so that a Class 10 pass-out already has a recognised, entry-level grounding in mechanical trade skills. The Maharashtra SSC Mechanical Technology Pre-Voc/NSQF study guide has 13 sections and about 4,860 words.
01Safety Practices and Workshop Discipline
This domain tests whether you can spot a hazard, select the right protective equipment and extinguisher, and describe safe working around machines, electricity and housekeeping. Eye protection is compulsory for chipping, grinding, drilling and any operation that throws chips.
396 words, about 2 min02Engineering Materials and Basic Metallurgy
The exam checks classification of metals, carbon percentages, properties, simple heat treatment and the purpose of basic tests. Plain carbon steel: low carbon up to 0.3% C (soft, ductile, weldable, used for bolts and sheet); medium carbon 0.3-0.6% C (axles, gears after treatment); high carbon 0.6-1.5% C (springs, files, drills, punches).
354 words, about 2 min03Hand Tools
Questions here ask you to choose the correct tool, know its angles and parts, and describe proper care. Scriber with a hardened point, surface plate, V-block for round work, angle plate, try square, dividers, and punches.
368 words, about 2 min04Measuring Instruments and Bench Work
This domain tests least count, correct reading of vernier and micrometer, zero-error correction, and the sequence of bench operations. Vernier caliper: least count = value of one main scale division divided by the number of vernier divisions.
379 words, about 2 min05Basic Fitting
Fitting is bench work that produces a part which mates with another within specified limits. The exam tests terminology of limits and fits and the correct sequence of operations.
342 words, about 2 min06Drilling, Tapping and Threading Operations
The exam covers twist drill geometry, spindle speed calculation, tap drill size and thread terminology. A twist drill has a shank (straight or taper), a fluted body and a point.
407 words, about 2 min07Lathe and Basic Machining Operations
Questions cover lathe parts and their functions, cutting parameters, taper calculation and thread cutting practice. Bed, headstock with spindle and chuck, tailstock for centres and drilling, carriage made up of saddle, cross slide and compound rest, tool post, apron with half-nut lever and feed selection, lead screw for threads and feed rod for turning, plus steady and follower rests for slender work.
392 words, about 2 min08Welding, Brazing and Soldering Processes
This domain tests joining processes, their temperature ranges, electrode coding, flame types and common weld defects. Manual metal arc (SMAW) uses a coated consumable electrode; the coating gives shielding gas and slag.
342 words, about 2 min09Engineering Drawing, Reading and Sketching
The exam tests line conventions, first and third angle projection, dimensioning rules, sections and freehand sketching. Continuous thick lines show visible outlines; continuous thin lines are for dimension, projection and hatching; short dashes show hidden edges; thin chain lines mark centre lines and pitch circles; chain lines thickened at the ends mark cutting planes; wavy lines show breaks.
408 words, about 2 min10Power Sources
This domain covers workshop electrical supply, protective devices, motor types, starters, earthing and safe practice. Indian practice is 230 V single phase, 415 V three phase at 50 Hz.
372 words, about 2 min11Fasteners and Assembly Practice
The exam tests fastener types and their applications, thread systems, locking devices and correct tightening sequence. Through bolt with nut, machine screw, stud (screwed into a casting with a nut on the free end), cap screw, grub screw and self-tapping screw for sheet and plastics.
362 words, about 2 min12Maintenance, Inspection and Quality Basics
This domain tests maintenance types, non-destructive testing methods, gauge use and the basic quality tools and terms. Preventive maintenance is scheduled cleaning, lubrication, adjustment and part replacement before failure.
369 words, about 2 min13Employability Skills and Workplace Communication (NSQF)
This section tests the NSQF framework, workplace communication, technical documentation, work ethics and basic financial and digital literacy. NSQF is the National Skills Qualifications Framework with ten levels, each defined by learning outcomes in knowledge, skill, aptitude and responsibility.
