Set 1
Engineering drawing internal exam Date: 2-11-15
WRITE TWO QUESTIONS FROM THE GIVEN INTERNAL CHOICE TIME: 1 hour
1. Trace a conic section, when the distance of the focus from the directrix is 35 mm and eccentricity equal to 3/2. Name the curve.
(OR)
A line AB, 75 mm long, is inclined at 450 to the HP, and 300 to the VP. It’s one end 25 mm above HP, and 20 mm in front the VP. Draw the projections of the line.
2. A pentagonal prism is resting on one of the corners of its base on the HP. The longer edge containing that corner is inclined at 450 to the HP. Draw the projections of the solid.
(OR)A cone, base 50 mm diameter and axis 70 mm long is reacting on its base on the HP. It is cut by a section plane perpendicular to the VP. Inclined at 450 to the HP, and cutting the axis at a point 30 mm from the apex. Draw its front view, sectional top view.
Set 2
Engineering drawing internal exam Date: 2-11-15
WRITE TWO QUESTIONS FROM THE GIVEN INTERNAL CHOICE TIME: 1 hour
1. Trace a conic section, when the distance of the focus from the directreix is 40 mm and eccentricity equal to 1. Name the curve draw.
(Or)
A point P is 15 mm above the H.P. and 20 mm in front of the V.P. Another point Q is 25 mm behind the V.P. and 40 mm below the H.P. draw projections of P and Q keeping the distance between their projectors equal to 90 mm. Draw straight lines joining (i) their top views and (ii) their front views.
2. Draw the projections of a cylinder 75 mm diameter and 100 mm long, lying on the ground with its axis inclined at 300 to the VP. And parallel to the ground.
(Or)
A cylinder of 40 mm diameter, 60 mm height and having its axis vertical, is cut by a section plane, perpendicular to the VP inclined at 450 to the HP. and intersecting the axis 32 mm above the base. Draw its front view, sectional top view.
Set 3
Engineering drawing internal exam Date: 2-11-15
WRITE TWO QUESTIONS FROM THE GIVEN INTERNAL CHOICE TIME: 1 hour
1. Trace a conic section, when the distance of the focus from the directrix is 30 mm. Eccentricity equal to 2/3, name the curve draw a normal.
(Or)
Two points A and B are in the H.P. The point A is 30 mm in front of the V.P., while B is behind the V.P. The distance between their projectors is 75 mm and the line joining their top views makes an angle of 450 with xy. Find the distance of the point B from the V.P
2. A pentagonal prism is resting on one of the corners of its base on the HP. The longer edge containing that corner is inclined at 450 to the HP. Draw the projections of the solid.(Or)
A cone, base 50 mm diameter and axis 70 mm long is reacting on its base on the HP. It is cut by a section plane perpendicular to the VP. Inclined at 450 to the HP, and cutting the axis at a point 30 mm from the apex. Draw its front view, sectional top view.
