Total No. of Questions : 12] [Total No. of Printed Pages : 4 [3661]-20 F. E. Examination - 2009 ENGINEERING GRAPHICS - II (2003 Course) Time : 4 Hours] [Max. Marks : 100 Instructions : (1) Answer any one question from each unit. (2) Answers to the two sections should be drawn on separate drawing sheet, use back side of sheet. (3) Figures to the right indicate full marks. (4) Use of electronic pocket calculator is allowed. (5) Assume suitable data, if necessary. (6) Retain construction lines; marks are reserved for dimensioning and good presentation. SECTION - I UNIT - I Q.1) A line AB has its ends A and B, 20 and 60mm in front of VP respectively. The distance between end projectors is 80mm. The line makes 30o to HP with HT 10mm infront of VP. Draw projections and determine : (1) Length of Line AB (2) Angle made by Line AB with VP (3) Locate V T [16] OR [3661]-20 1 P.T.O. Q.2) A man and a child is standing on the ground, 6 meter from the electric pole, creates the shadow of the man and the child as 1.7 meter and 0.8 meter long respectively. The height of the pole is 8m. Find the height of the man and the child. If the angle between the shadows is 110o. How far the man is standing from the child ? [16] UNIT - II Q.3) A pentagonal plane of sides 30mm is resting on a corner in VP with its surface making an angle of 40o to the VP. The edge opposite to the corner which is resting in VP is inclined at 35o to the HP. Draw the three principal views and find angle made by plane with HP. [17] OR Q.4) A regular hexagonal plate of 35mm side is resting on one of its corner on the ground. The diagonal through that corner is inclined at 40o to HP and 30o to VP. Draw the projection of plate. Determine the inclination of the plate with VP. [17] UNIT - III Q.5) A frustum of a pentagonal pyramid base 50mm side, top 25mm side and axis 75mm long, has its side of base in VP making an angle of 30o to the HP. Draw the projections of the solid when its axis is inclined at 60o to the VP. [17] OR Q.6) A tetrahedron of 75mm long edges having one edge parallel to HP and inclined 45o to VP. While a face containing that edge is vertical. Draw its three views. [17] SECTION - II UNIT - IV Q.7) A cube of 60mm side is kept on HP on one of its faces in such a way that edges on HP are equally inclined to VP. It is cut by an AIP so that true shape of section is a regular hexagon. Draw FV; sectional TV and true shape of section. Determine length of side of hexagon. State the angle made by AIP. [16] OR [3661]-20 2 Contd. Q.8) A cone base 70mm diameter and axis 80mm long, has its axis parallel to the VP and inclined at 45o to the HP. A sectional plane cuts the cone through the mid point of the axis and parallel to HP. Draw the front view sectional top view and an auxiliary top view on a plane parallel to the axis. [16] UNIT - V Q.9) A pentagonal pyramid with side of base 40mm and axis height 70 mm is kept on HP on its base with side of base parallel to VP and closer to VP. A string is wound from the corner of the base which is nearest to observer around the triangular faces and is brought back to same point. Show the shortest path of string in FV and TV. [17] OR 30 100 Q.10) Draw the development of the lateral surface of the cut cylinder as shown in fig. [17] 35 15 60 Cylinder diameter 60 height 100mm Regular Pentagon side 30mm Centre of Pentagon 50mm from base and 15mm offset to right. [3661]-20 3 P.T.O. UNIT - VI Q.11) A pentagonal prism side of base 60mm and height 80mm is lying on the HP on one of its pentagonal base such that an edge of the base is parallel to VP and nearer to it. The axis of prism is parallel to VP and perpendicular to HP. The prism is pentrated by horizontal cylinder of dia 60mm the axis of cylinder and prism bisect each other at right angles both in front view and top view. Draw the projections showing the curves of intersection. [17] OR Q.12) A cylinder of diameter 60mm and axis 70mm is kept on HP with axis perpendicular to HP and parallel to VP. Another solid, a square prism with side of base 40mm and axis 100mm intersects the cylinder. The axis of prism is parallel to both HP and VP and 15mm in front of the axis of the cylinder. The axis of prism is 45mm above HP and rectangular faces are equally inclined to HP. Draw the projections [17] showing the curves of intersection. [3661]-20/4
