ASSIGNMENT-4
1).A thin hexagonal lamina of 30 mm side with a central hole of 30 mm diameter is resting on H.P. on one of its corner. Draw the projections of lamina when diagonal through resting corner is 30° to both H.P. and V.P.
2&3). A regular hexagonal plane with side 40 mm is resting on one of its sides. Draw the projections of the plane when it is inclined at 30° to H.P. and the side on which it rests on H.P. makes 45° with V.P.
Note:Assignment4 problem no.2 and 3 are same.
4). An elliptical plane with major axis 70 mm and minor axis 50 mm is inclined to H.P. such that the top view of the plane is circle. Draw the projections of the plane when the major axis is inclined at 30° to the V.P. Find the inclination of the plane with H.P. Use concentric circle method to draw the top view of the plane in the initial stage.
5).A pentagon of 40 mm side is resting on one of its corners on the V.P. The edge opposite to that corner makes an angle an angle of 30° to the H.P. The surface of the pentagon is inclined at 45° to the V.P. Draw its projections.
