Answer any one question

1. A room measures 8m long, 5m wide and 4m high. An electric bulb

hangs in the center of the ceiling and 1m below it. There is a black spot

on the bulb surface. When the bulb is switched on the image of the

black spot falls on one of the corner of the room at a height of 1.25m

above the floor. Neglecting the size of the bulb, draw the projections of

the line connecting the black spot on the bulb and its image formed on

the wall, also determine the true length of the line connecting the black

spot and the its image and the slope it makes with the floor. [8 marks]

2. Three vertical poles AB, CD, and EF are respectively 2m, 4m, and 8m

long and standing on the floor. There ends B, D and F are on the floor

and are the corners of an equilateral triangle of side 5m. Determine the

distances between the top ends of the poles, i.e., AC, CE and AE. Find

also their inclination to the floor. [8 marks]

a. A square pyramid of base 30 mm and height 60 mm rests with

one of its base edges on HP. The axis of the pyramid makes an angle of

450 with the HP. Draw its projections[6 marks]

b. Arrow indicates the direction to obtain the view from the front.

Figure shows the isometric views of a machine component with all

dimensions. Draw its view from the front, the view from above and the

view from the right. [7 marks]

4. A square pyramid with side of base 30 mm, and axis 50 mm long is

resting on its base on HP with an edge of the base parallel to VP. It is cut

by a section plane perpendicular to VP and inclined at 450 to HP. The

section plane is passing through the midpoint of the axis. Draw the true
