(ii) Topview. (20+12 = 32)
SECTION C
Answer any THREE Questions. Each question carries 16 marks.
Q.3 A generating circle of 40 mm diameter rolls outside the directing circle of 150 mm diameter. Draw the path described by a point on the rolling circle and name the curve described. Draw tangent and normal to the curve at 100 mm from the center of the directing circle. (16)
Q.4 A triangle prism of 30 mm side and height 70 mm is resting on lateral surface on H.P. The axis of the solid is 45° to V.P. Draw its projection. (16)
Q.5 The distance between the end projectors of a line is 70 mm and the projectors through the traces are 110 mm apart. One end of the line is 10 mm above H.P. If top view and front view makes 30° and 45° respectively with line of intersection of H.P. and V.P., draw the projections of the line. Also locate its traces and determine true length, true inclination with H.P. and V.P. (16)
