part – A [Marks 2*10=20]

a) When a point is situated in the 1st quadrant it will be located above the HP and in front of VP. (True / False)

b) What do you mean by single stroke lettering?

c) discuss the procedure for working out actual shape of surface inclined to HP.

d) A solid with 2 identical ends is called________.

e)A cone is generated by the revolution of________about its latitude.

f)What do you understand by Frustum?

g)A________is a polyhedron composed of a regular polygon and a number of triangular faces.

h) The actual shape of a part will be seen in the front view of an object when the part plane is to the VP.

j) Intersection of plane surfaces and curves surface provide

Section-B [Marks : eight Each]

Q2) (a)section lines are inclined at___________angle to__________line.

b)Show the subsequent lines schematically and discuss their significance :

(i) Outline or Object line

(ii) Centre line or Locus line

Differentiate ranging from 1st angle projections and 3rd angle projections
employed in engineering drawing.

Q3) The projection of the ends of a line EF are 60 mm apart, end E is 15mm above HP and 20 mm in front of VP. End F is 10 mm beneath HP and 35mm behind VP. Determine its actual length, traces and inclination of the line with the 2 reference Planes.

Q4) A right circular cone base 50 mm diameter, axis 65 mm long, when it is resting on HP on a point of its base circle, with axis making an angle 30 with HP and Plan of axis 45 with VP.

Q5) A pentagonal pyramid of base 35 mm and height 60 mm rests with its base on HP such that 1 of its base edges is perpendicular to VP. A part plane inclined at 45 to HP and perpendicular to VP cuts the pyramid through its axis at 25 mm from the apex Draw the sectional front
and top views and actual shape of the part.

part - C [Marks : eight each]

Q6)A square prism of base 45mm and height 20mm rests centrally on the top face of a cylinder of 60 mm diameter and 30 mm height. Draw the isometric projects of the combined solid.

Q7) elaborate the uses of freehand sketching in engineering field? define the steps to be followed in sketching a square?

Q8) Draw the development of the cone having base diameter 40 mm and axis height 50 mm. The cone has been cut by a straight part plane parallel to its base at a distance of 30 mm from its base.

Q9) A vertical cylinder of 50 mm diameter and height 70 mm,is standing on its base on HP and with the axis perpendicular to HP. It is completely penetrated by a different horizontal cylinder of 45 mm diameter and 80 mm long. The axis of the horizontal cylinder is parallel to VP and the 2 axis
bisect every other. Draw the projections showing curves of intersection.
