On map of Patna City 1cm represents 1km. Construct a scale to measure the distance between Bihar Engineering University and Patna University is 6 km. Also indicate on scale, the distance between Patna railway station and Rajendranagar Terminal which is 3 km and 7 hectometers.

Construct the involute of a pentagonal of sides 25 mm. Draw the tangent and normal to the involute at a point 100 mm from the center of the pentagonal.

A wheel of motorcycle 60 mm in diameters roll on a straight horizontal road. Draw the locus of a point 'P' on the periphery of the wheel for one revolution of the wheel. Initially point P is farthest from road.

The front view of 85 mm long straight line AB measure 60 mm while its top view measure 70 mm. Draw the projection of AB if it's end A is 10 mm above HP and 20 mm behind VP, while it's end B is in first quadrant. Draw the projections of line and determine the inclination of line AB with the reference planes.

A semi-circular plate of 40 mm diameter has its straight edge in the V.P. and inclined at \( 45^{\circ} \) to the H.P. The surface of the plate makes an angle \( 30^{\circ} \) with the V.P draw its projections.
