2. A circle of 50 mm diameter rolls along a straight line without slipping. Draw the curve traced by a point P on the circumference for one complete revolution of the circle. Name the curve. Draw a tangent to the curve at a point 40 mm from the line.

3. A point A is 20 mm above H.P. and 30 mm in front of V.P., another point B is 25 mm below H.P. and 40 mm behind V.P. Draw the projections of the line joining A and B. Also find the true length and true inclinations with H.P. and V.P.

4. A line AB 80 mm long is inclined at 30° to the H.P. and 45° to the V.P. Its end A is 20 mm above the H.P. and 30 mm in front of the V.P. Draw the projections of the line.

5. Draw the projections of a circle of 50 mm diameter resting in the H.P. on a point A on the circumference; its plane inclined at 45° to the H.P. The top view of the diameter through the point A makes an angle of 30° with the V.P.
