- Sectional Front View
- Right Hand Side View
2. A wheel rolls over the horizontal straight line path and covers 1980 mm distance in one rotation. Draw the path traced by the point P which is initially at the point of contact between the wheel and the horizontal straight line. Name the path traced by the point P.
3. The top view of an object is a square of 60 mm side while the front view is a circle of radius 30 mm. Draw the isometric projection of the object.
4. A square plate of 60 mm side is resting on HP on one of its corners in such a way that its surface makes an angle of 45° to HP. Draw the projections of the square plate when diagonal passing through the corner on HP makes an angle of 30° to VP.

5. The top view of 75 mm long line AB measures 65 mm, while the length of its front view is 50 mm. Its one end A is in the H.P. and 12 mm in front of the V.P. Draw the projections of line AB and its inclinations with the H.P. and the V.P.
6. ABC is an equilateral triangle of side 60 mm long: Its corner A is on H.P and side BC is 20 mm above HP. Draw the projections of the triangle when side BC is inclined to V.P at an angle of 50°
7. Classify the solids. Differentiate prism and pyramid with figure.
8. A pentagonal prism rests on one of its edges of the base on H.P. with its axis inclined at 45° to the H.P. The top view of the axis is inclined at 30° to the V.P. Draw the projections of the prism, assuming the edge of the base to be 30 mm and the axis 70 mm long.
9. Draw the symbol for first and third angle projection. Describe the types of system of dimensioning with figure.

10. A cube with a 30 mm side resting on one of its corners on HP. Draw the projections when the base is inclined at 45° to HP and axis parallel to VP.
11. Draw a plain scale to show kilometer and hectometer when R.F. = 1/35000 and long enough to measure 5 km. Measure 3.7 km on scale
12. A cone, base 40 mm diameter and axis 60 mm long, rests on its base on the HP. It is cut by a section plane perpendicular to the VP and parallel to one of its generators and passing through a point on the axis at a distance of 25 mm from the apex. Draw the sectional top view
13. An inelastic string 150 mm long has its one end attached to the circumference of a circular disc, of 40 mm diameter. Draw the curve traced out by the other end of the string when it completely wound around the disc keeping the disc always tight
14. Draw a rectangle of 120mm X 60 mm. draw ellipse in it.
