1. (a) A circle of 50 mm diameter rolls along a line. A point on the circumference ofthe circle is in contact with the line in the beginning and after one completerevolution. Draw the cycloidal path of the point. Draw a tangent and normalat any point on the curve. (20)

2. (a) A line AB, 90 mm long, is inclined at 45◦ to the H.P., and its top view makesan angle of 60◦ with the V.P. The end A is in the H.P and 12 mm in front ofthe V.P. Draw its front view and find its true inclination with the V.P. (20)

OR

2. (b) A rectangular plate 70 × 40 mm has one of its shorter edges in the VP inclinedat 40◦ to the HP. Draw its top view, if its front view is a square of side 40 mm.

(20)

3. (a) A pentagonal prism of edge of base 30 mm and axis 70 mm long rests withone of its rectangular faces on HP and the ends inclined at 30◦ to VP. Drawits projections. (20)

OR

3. (b) Draw the projections of a hexagonal pyramid with side of the base 30 mm andaxis 70 mm long, when it is resting with one of the base sides on HP suchthat the triangular face containing that side is perpendicular to HP and axisis parallel to VP. (20)

4. (a) A cone, diameter of base 60 mm and height 60 mm, is resting on H.P. on itsbase. It is cut by a plane inclined to H.P at 30◦ and perpendicular to VP.The cutting plane passes through one of the extreme generators at a height of10 mm above the base. Draw the front view, sectional top view and the trueshape of the section. (20)

OR

4. (b) A cone of base 60 mm and height 80 mm is resting with its base on HP. Aninsect starts from a point on the circumference of the base, goes round thesolid and reaches the starting point in the shortest path. Find the distancetravelled by the insect and also the projections of the path followed by it. (20)

5. (a) Draw the isometric projection of a frustum of a hexagonal pyramid when itis resting on its base on the HP with two sides of the base parallel to the VP.The side of base is 20 mm and the top 8 mm. The height of the frustum is55 mm. (20)

OR

5. (b) A rectangular prism of base 30 × 15 mm and height 40 mm rests on the groundon one of its base ends with one of the lateral edges touching the PP and theshortest edge of the base inclined at angle of 40◦ to the PP. The nearest verticaledge is 15 mm to the left of the station point which is at a distance of 55 mmin front of the PP and 30 mm above the ground. Draw the perspective viewof the prism. (20)
