1. a) Construct a diagonal scale of 1:25 to read metres, decimeters and centimeters and long enough to measure 4m. Mark on it a distance of 2.47m.
b) Draw a parabola in the parallelogram of sides 120 mm and 80 mm, take the longer side as horizontal base. Consider one of the included angles between the sides as 60 degrees. [15]
2. A 70 mm long line PQ is inclined at 450 to the H.P., and its top view measures 50 mm. The end P is 15 mm above the H.P. while the V.T. of the line is 20 mm below the H.P. Draw its projections and determine its inclination with the V.P. Also, locate its H.T. [15]
3. A square lamina with a 50 mm side rests on the H.P., on one of its corners, such that the diagonal through that corner is parallel to the V.P. and inclined at 30 to the H.P. Draw its projections when the lamina is perpendicular to the V.P. Measure the distance of the top mostcornerfromtheH.P. [15]
4. A square prism with a base having 40 mm sides and height 60 mm is kept on its base on the H.P. such that one of its rectangular faces makes an angle of 300 with V.P. It is cut by a section plane parallel to V.P. such that the true shape of the section is a rectangle with 30 mm and 60 mm sides. Draw its sectional front view and top view. [15]
5. A vertical cylinder 80mm diameter is penetrated by another cylinder of the same size and its axis is parallel to both HP and VP. Axis of vertical cylinder is intersecting the axis of horizontal cylinder. Draw the projections showing curves of intersection. [15]
6. Draw an isometric projection of a frustum of the pentagonal pyramid with a 40 mm base side, 20 mm top side and 35 mm height resting on its base in the H.P. [15]
7. Draw the elevation, top view and side view of the object shown in figure. All dimensions are in mm. [15]
8. A rectangular prism of base 30 mm × 40 mm rests on the GP on its base with a corner of the base touching the PPP. The longer base edge is on the right and inclined at 300 to the PPP. The station point is 50mm in front of the PPP and 75 mm above the GP. If the central plane is 20 mm on the left of the axis of the pyramid. Draw a perspective projection of the pyramid. [15]
