Time hours Maximum Marks: 70
Note: Questions no. 1 and 2 are compulsory and are to be attempted on the Answer Script and others on the drawing sheet. Answer any two questions from the remaining four questions.

1. Attempt any seven questions. All questions carry equal marks. 7 x 2=14 What is the conventional representation of First-Angle Projection? Give the names of two conic sections obtained by the intersection of a right circular cone by a cutting plane. Differentiate between a perpendicular plane and an oblique plane. Fill the blanks with appropriate words selected from the list When a line is perpendicular to anyone of the reference planes, it will be to other reference plane (inclined or parallel).

(ii) True shape of a plane is obtained in that reference plane where it is ___(perpendicular or parallel). Mention True or False: Representative fraction value in case of enlarging scale will always be directly equal to one.

(ii) Eccentricity of a hyperbola is always greater than one. Calculate the developed length of a cylinder which has a base diameter of 70 mm. Explain frustum of a cone with the help of a simple sketch. Make a list of at least four different types of pyramids as per the shape of the base.

2. As per the given projections of a line find out the true length of the line. <img src='./qimages/8526-2(a).jpg'> Draw the projections and state the quadrants to which the following points belong: 4 Point in H.P. and 50 mm in front of V.P.

(ii) Point 40 mm above H.P. and 40 mm behind V.P. Calculate the length of the scale needed to measure up to 6 metres given that

R.F. 3 200. 4

OR

Differentiate between Reducing Scale and Enlarging Scale. 4

3. A line 75 mm long, is inclined at 45° to H.P. and 30° to V.P. Its one end is in the H.P. and 40 mm in front of V.P. Draw its projections. 21

4. Construct a parabola, when the distance of the focus from the directrix is 60 mm. 21

5. A regular hexagonal plane of side 40 mm rests in H.P. on one of its sides. Draw its projections when its surface is inclined at 45° to H.P. and perpendicular to V.P. 21

6. Draw the isometric view of a cone, two views of which are shown in the given figure. 21 <img src='./qimages/8526-6.jpg'>
