Semester Question Bank for Engineering Graphics.

  1. A line AB 80 mm long, inclined at 45° to HP & 30° to VP. Draw its projection when its end point A is 15 mm above HP and 10 mm in front of VP.
  2. Explain clearly the difference between the first-angle projection method and the third-angle projection method.
  3. State the quadrant in which the following points are situated:
    • (a) A point P; its top view is 40 mm above XY; the front view, 20 mm below the top view.
    • (b) A point Q; its projections coincide with each other 40 mm below XY.
  4. Construct a parabola having a base equal to 150 mm and height equal to 75 mm by the tangent method.
  5. A regular pentagon of 25 mm side has one side on the ground. Its plane is inclined at 45° to the H.P. and perpendicular to the V.P. Draw its projections and show its traces.
  6. A right regular hexagon prism, edge of base 30 mm and height 75 mm, is resting on its ground such that one of its base edges is parallel to V.P. A cutting plane perpendicular to the V.P. and inclined to the H.P. at 45° meets the axis at a distance of 10 mm from its top end. Draw its front view, sectional top view, sectional side view, and the true shape of the section.
  7. Discuss different types of engineering curves, and draw an involute of a circle of 50 mm diameter.
  8. Explain the differences between 1st angle and 3rd angle methods of projection in tabular form, and draw the projections (front, top, and side views) of a straight line of 60 mm length inclined 30° to the horizontal plane (H.P.) and parallel to the vertical plane (V.P.), in the 1st angle projection method.
  9. Discuss different types of solids, and draw the projections (front, top, and side views) of a right pyramid with a square base of 25 mm side length and 60 mm height. Next, show the sectional top view of the pyramid cut by a horizontal plane at a height of 30 mm on the same drawing.
