Engineering Drawing Examination

Study Notes

(a)* List recognized drawing sheet sizes, including length and width dimensions.
(b)* Draw a pentagon with a 25mm side length using the three-circle method.
(c)* A straight line PQ, 60mm long, has end P 20mm above the horizontal plane (H.P.) and 15mm in front of the vertical plane (V.P.). Draw the projections if the line is inclined at 30° to the V.P. and its front view is inclined at 45° to the XY line. Find the true inclination with the H.P.
(c) (OR)* The distance between the end projectors of line AB is 65mm. End A is 15mm above the H.P. and 25mm in front of the V.P. End B is 40mm above the H.P. and 50mm in front of the V.P. Draw the projections and find the true length of line AB.

(a)* Draw first angle projection method and third angle projection method symbols.
(b)* Draw a regular hexagon with a 40mm side using the universal method.

(a)* Explain chain and parallel dimensioning with a sketch.
(b)* Draw an Archimedean spiral for 390°. The smallest and greatest radii are 10mm and 70mm, respectively.
(c)* Figure 1 shows a pictorial view of an object. Draw the front view and right-hand side view using the third-angle projection method, viewed from the X direction.
(OR)*
(a)* List pencil grades and their applications.
(b)* Draw an ellipse using the concentric circle method. The major axis is 100mm and the minor axis is 70mm.
(c)* Figure 2 shows a pictorial view of an object. Draw the front view and plan using the third angle projection method, viewed from the X direction.

(a)* Divide a line AB, 90mm long, into 8 equal parts.
(b)* Draw an involute of a square with a 30mm side.
(OR)*
(a)* Write the various kinds of lines used in engineering drawing.
(b)* Draw a parabola using the rectangle method. The base and axis are 120mm and 100mm, respectively.
(c)* Figure 4 shows two views of an object. Draw its isometric projections and show necessary dimensions.

(a)* Point A is 10mm above H.P and 20mm in front of V.P. Point B is 20mm below H.P and 30mm behind V.P.
(b)* Draw an involute of a circle with a 30mm diameter.
(c)* The end A of line PQ, 100mm long, is 20mm above H.P. and 30mm in front of V.P. The line is inclined at 45° to H.P. and 30° to V.P. Draw the projections and find the apparent angles.
(OR)*
(a)* Explain dimensioning methods with sketches.
(b)* Draw an ellipse using the oblong method. The major axis and minor axis are 100mm and 70mm, respectively.
(c)* A line MN, 90mm long, is inclined at 30° to H.P. The plan of MN makes an angle of 45° with XY. Draw the projections and find the inclination with V.P. The end M is 15mm above H.P. and 10mm in front of V.P.
