1. 1(a)12 marksConstruct an ellipse with a major axis of 160 mm and a minor axis of 106 mm using the focal point method.
2. 1(b)8 marksConstruct a tangent to the ellipse at point C on the curve, inclined at 30° to the major axis.
3. 220 marksDraw the outline of the belt-drive pulley around two pulley wheels with a tensioning wheel between them as shown in Figure 1, indicating points of tangency and showing construction methods clearly.
4. 3(a)8 marksDraw the circle of diameter 70 mm with centre O and establish the given points A and B according to the dimensions shown in Figure 2.
5. 3(b)12 marksConstruct a circle that passes through points A and B and touches the given circle, showing all construction lines clearly.
6. 4(a)10 marksConstruct a regular heptagon with a side length of 40 mm.
7. 4(b)10 marksConstruct a similar figure that has twice the area of the regular heptagon constructed in (a).
8. 5(a)8 marksDraw the two given views of the intersecting cylinder and triangular prism shown in Figure 3.
9. 5(b)12 marksDraw an end view looking in the direction of arrow 'E', showing the curve of interpenetration and all hidden detail lines.
10. 6(a)8 marksDraw full size the given surface development and incomplete elevation of the cone with triangle ABC lying on its surface as shown in Figure 4.
11. 6(b)12 marksComplete the elevation to show triangle ABC lying on the surface of the cone, showing all hidden details and construction lines clearly.
12. 7(a)6 marksCopy the two given orthographic views of the rectangular channelled section shown in Figure 5.
13. 7(b)14 marksDraw the auxiliary elevation of the channel projected onto X1-Y1 as viewed in the direction of arrow 'A'.
14. 820 marksDraw an isometric view of the block shown in Figure 6, making point 'S' the lowest point. Do not copy the given views.
