As you want to get the PTU B.Tech 1st Sem-Engineering Drawing previous years question papers so here is the information of the same for you:

Some content of the file has been given here:

1. a). Where and why a cutting plane is drawn in a drawing?

b) What do you mean by single stroke letters?

c) Define refraction fraction (R.F).

d) Draw a symbol of first angle projections.

e) Why the projections of an object are not drawn in 2nd and 4th quadrants?

f) What is the trace of a straight line?

g) Define plane.

Section-B

2. Draw a free hand sketch of a stool which you have seen in your drawing

room?

3. A vertical cylinder of 50mm diameter and height 70mm standing on its base

on H.P is completely penetrated by a horizontal cylinder of 35mm diameter

and 70mm long such that their axes bisect each other at right angles and are

parallel to V.P. Draw the curves of interpenetration in front view?

4. A straight line AB 50mm long makes an angle of 30° to the H.P. The end A is

12mm above the HP and 15mm in front of the VP. Draw the top view and

front view of the line AB.

5. Write in double stroke vertical and inclined style, the following statements

using ratio 7:4.

Section-C

6. A square lamina ABCD of 25mmside has its H.T parallel to and 15mm below

xy line. It has no V.T. Draw its projections when all the sides are equally

inclined to the HP.

7. (a) A cube of 40mm edges is resting on its one of its faces on HP with a

vertical face inclined to 30° to V.P. It is cut by a section plane parallel to the

VP and passes 15mm away from the axis. Draw its top view and sectional

front view.

(b) A cube of 40mm sides rests centrally on a square block of 60mm edges

and 20mm thick. Draw the isometric projections of the two objects with the

edges on the two blocks mutually parallel to each other.

8. A pentagon prism of 25mm base edges and 50mm long, resting on its base

with an edge of base at 45° to the VP. The prism is cut by a section plane

V.T. inclined at 30° to the HP and passes through a point 25mm from the

base along its axis. Develop its lateral surface of the truncated prism.

9. Draw the three views of a cube 30mm side when it is resting on its base on

HP with one of the base edges making an angle of 45° to the VP.

1. (a) Why the layout of the sheet is necessary?

(b) Sketch the center line, cutting plane line and long break line.

(c) Give the difference between reducing and increasing scale.

(d) Following symbol represents first or third angle projection.

Fig.

(e) Sectioned portion is represented by……………lines.

(f) What is the principle of development of surfaces?

(g) A solid having four equal equilateral triangular faces is called……..

(h) What is an orthographic projection?

(i) A straight line is defined as the……………………distance between two points.

(j) What is the trace of a plane?

Section-B

2. Write freehand the following sentence using inclined capital letters of 8 mm size in single stroke

using 7:5 ratio.

‘Practice makes a man perfect’

3. What do you understand by thickness of lines and various line groups?

4. A line 70 mm long makes an angle of 30° from HP and lies in a plane perpendicular to both the HP

and VP. Its one end is in HP and the other end is in VP. Draw its projections.

5. A triangular prism, side of base 45 mm and length of axis 75 mm lying on one of its rectangular

faces on HP such that its axis is parallel to both HP and VP. It is cut by a section plane parallel to

HP at a distance of 22 mm from the HP. Draw its front view and sectional top view.

Section-C

6. A square prism of side 30 mm and 40 mm height is resting on HP. A vertical square bore of 10 mm

side is cut through its face reaching other square face of the prism. Draw the isometric projection of

the prism.

7. A right cylinder of 30 mm diameter and 35 mm height of axis, is cut by a section plane inclined at

30° to the HP and passes 18 mm from base along the axis. Draw the development of the truncated

cylinder.

8. A vertical cylinder of 50 mm diameter and height 60 mm, standing on its base on HP is completely

penetrated by horizontal cylinder of 30 mm diameter and height 60 mm. Their axis bisects each

other at right angles and is parallel to VP. Draw the curves of projection in front view.

9. Draw the view from the front (arrow side) and the view from the right of the following object (all

dimensions in mm).
