bike has the wheel of 1 meter diameter .Draw the locus of the point on the

circumference of the motor bike wheel for one complete revolution. [16]

3.a) A point ‘A’ is 40mm from both the reference planes. Draw its projections in all

possible positions.

b) Two pegs fixed on a wall are 4.5m apart. The distance between the pegs measured

parallel to the floor is 3.6m. If one peg is 1.5m above the floor; find the height of

the second peg and the inclination of the line joining two pegs with the floor.

4. Draw the projections of a rhombus having diagonals 125mm & 50mm long the

smaller diagonal of which is parallel to both the parallel lines, while the other is

inclined at 300 to H.P. [16]

5. A pentagonal prism is resting on one of the corners of its base on the H.P. The

longer edge containing the corner is inclined at 450 to the H.P. The axis of the

prism makes an angle of 300 to the V.P. Draw the projections of the solid. [16]

6. A line AB, 75mm long is in the second quadrant with the end A in the H.P. and

the end B in the V.P. The line is inclined at 300 to the H.P. and at 450 to V.P. Draw

the projections of AB. [16]

1. Two points A and B lie on a straight line through the centre C of a circle of 50mm

diameter, rolling along a fixed straight line. Draw and name the curves traced out

by the points A and B during one complete revolution of the circle. AC =30mm;

BC=52mm. [16]

2. A fixed point is 80mm from a fixed straight line. Draw the locus of a point P

moving in such a way that its distance from the fixed straight line is twice its

distance from the fixed point. [16]

3.a) A point A is situated in the first quadrant. Its shortest distance from the

intersection point of H.P., V.P, and auxiliary plane is 50mm and it is equidistant

from the principal planes. Draw the projections of the point and determine its

distance from the principal planes.

b) A Point P is 20mm below. H.P. and lies in the third quadrant. Its shortest distance

from xy is 40mm. Draw its projections. [8+8]

4. Two apples on a tree are respectively 1.5m and 4 m above the ground, and 1.2m

and 2m from a 0.3 m thick wall, but on the opposite sides of it. The distance

between the apples, measured along the ground and parallel to the wall is

2.7m. Determine the real distance between the apples. [16]

5. A 600 set square of 125mm longest side is so kept that the longest side is in the

H.P. making an angle of 300 with the V.P. and the set square itself inclined at

450to the H.P. Draw the projections of the set square. [16]

6. A Tetrahedron of 75mm long edges has one edge parallel to the H.P. and inclined

at 450 to the V.P., while a face containing that edge is vertical. Draw its

projections.
