PART-B Answer Four

2. A stone is discharged from the ground level at an inclination of 450 to the ground which is horizontal. The shot returns to the ground at a point 250 metres from them the point of discharge. Trace the path of shot. obtain the direction of shot after it has traveled a horizontal distance of 200metre (scale 1:2000)

3. A line AB, 90mm long, is inclined at 450 to H.P and its top view makes an angle of 600 with xy. The end A is in the H.P and 12mm infront of V.P. Draw its front view and obtain its actual inclinations with the V.P.

4. The top view of a plane object is a regular hexagon of side 40 with a central circular hole of 30 diameter with 2 sides of the hexagon parallel to xy, when the surface of the object is inclined at 450 to the ground. Determine the actual shape of the solid.

5. Draw the projections of an octahedron of side 40 with 1 of its faces parallel to the H.P. and a side of that face inclined at 200 to the V.P.

6. Draw the development of a cylinder of 50 diameter and 75 high containing a square hole of 25 side. The sides of the hole are equally inclined to the base and the axis of the hole bisects the axis of the cylinder.

7. Draw the isometric view of a square nut of side 25 and height 25 coaxial hole of dia 10. The top of the nut is chamfered to a spherical shape of 35 radius for a distance(measured axially) equal to five at the corners.
