The Class 12 Engineering Graphics Machine Drawing Shaft Couplings PYQ PDF is available for free download. This chapter-wise file helps students revise Chapter 5 shaft-coupling drawing questions for the 2026-27 board exam.
- Covers muff coupling, split muff coupling, flange coupling, shafts, sunk keys, keyways, bolts, nuts, hatching and side-view projection.
- Includes 24 NCERT-based board-style questions because the local PYQ source set has no extractable chapter rows for this topic.
- Useful for practising sectional front view, side view, pitch circle, keyway placement and final darkening checks before full board-paper practice.
Student Feedback: Students can use this PYQ PDF to revise shaft-coupling drawing sequence without mixing muff, split muff and flange-coupling details.

Class 12 Engineering Graphics Shaft Couplings PYQ PDF
The PDF focuses on Class 12 Engineering Graphics Chapter 5, Machine Drawing - Shaft Couplings. The questions are arranged by marks so students can practise definitions, construction order and full machine-drawing prompts in a board-style sequence.
- Chapter: Chapter 5 Machine Drawing - Shaft Couplings
- Main theme: joining coaxial shafts with muff, split muff and flange coupling assemblies
- Practice type: objective, short construction, drawing-sequence, board-style and long-answer drawing questions
- Best use: revise centre line, sectional front view, side view, keyway, pitch circle and bolt placement before timed drawing practice
Questions Covered in Shaft Couplings PYQ PDF
The repeated examination pattern checks whether students can read the coupling type, choose the correct sectional view and keep shafts, keys, flanges and bolts aligned from one view to another.
| PYQ Cluster | Question Focus | Answer Skill |
|---|---|---|
| Part identification | Shaft, sleeve, sunk key, keyway, flange, bolt, nut and pitch circle | Name the part and state its assembly role |
| Sectional front view | Cutting plane, hatching, sleeve thickness, key seat and flange body | Draw visible edges and avoid unnecessary hidden lines |
| Side view projection | Projecting shaft circle, flange circle, bolt circle and nut positions | Transfer details accurately from the main sectional view |
| Board drawing practice | Complete muff, split muff and flange-coupling assembly questions | Finish views, labels and drawing conventions neatly |

Shaft Coupling Drawing Flow
Start every shaft-coupling answer with the common centre line, then place the shafts before adding sleeve, flanges, keyways and bolts. This keeps the sectional front view and side view aligned.
- Alignment: keep both shafts, sleeve or flange pair and keyway on the same centre line
- Sectioning: hatch sleeve and flange parts clearly, but do not hatch shafts cut lengthwise
- Projection: complete the side view after the sectional front view fixes every diameter
- Final check: darken visible outlines, place bolts evenly and keep construction lines light
Coupling Check Map
Use the coupling check map to avoid mixing the features of muff and flange couplings. Muff-coupling questions emphasise sleeve and keyway details, while flange-coupling questions emphasise pitch circle, bolt placement and flange thickness.

Class 12 Engineering Graphics Shaft Couplings PYQ FAQs
Ques. Where can I download Class 12 Engineering Graphics Machine Drawing Shaft Couplings PYQ PDF?
Ans. You can download the chapter-wise PYQ PDF from the PDF viewer and download link above.
Ques. Which shaft-coupling topics are important for PYQ practice?
Ans. Focus on muff coupling, split muff coupling, flange coupling, sunk key, keyway, flange circle, bolt placement, hatching and side-view projection.
Ques. Does this PDF include extracted previous-year rows?
Ans. No. The local source set has no extractable chapter rows for this topic, so the PDF uses NCERT-based board-style practice questions for shaft couplings.
Ques. How should students attempt shaft-coupling drawing questions?
Ans. Start with the centre line, place the shafts, block the sleeve or flanges, add keyways and bolts, project the side view and then finish hatching, labels and dark outlines.
