A rectangle, ABCD, has a diagonal of 150 mm and the length of one side = 70 mm. Construct (a) the rectangle (b) an ellipse within the rectangle with the major axis equal to the length and minor axis equal to the width of the given figure.

Figure 1 shows an irregular polygon, ABCDE with BC = 40 mm, AE = 60 mm, CD = 75 mm and ED = 45 mm. Construct (a) the given irregular polygon (b) a similar figure with its base AB, increased from 50 mm to 70 mm.

Figure 2 shows a template of a metal cutter. (a) Draw the given template showing clearly how the following are obtained: (i) The centres for arcs A and B (ii) The straight line from point 'P'. (b) Identify EACH point of tangency with a 'DOT'.

Figure 3 shows a crank mechanism in which OA revolves clockwise about O. The end, B, of the rod AB is constrained to move horizontally along XY.

OA = 30 mm AB = 110 mm AP = 50 mm

(a) Copy the given mechanism. (b) Plot the locus of P for one revolution of OA.

Copy the given mechanism.

Plot the locus of P for one revolution of OA.

Figure 4 shows the end elevation and incomplete front elevation of a cylinder intersecting a triangular prism. Construct (a) the given end elevation (b) the front elevation showing the curves of interpenetration. Show hidden details.

the given end elevation

the front elevation showing the curves of interpenetration. Show hidden details.

Figure 5 shows the elevation of two square sheet metal pipes 'A' and 'B' intersecting each other at $45^\circ$ . (a) Copy the given view. (b) Construct the development of pipe 'A' using the seam as shown on the given view.

Copy the given view.

Construct the development of pipe 'A' using the seam as shown on the given view.

Figure 6 shows the plan and elevation in orthographic projection of a truncated hexagonal prism. Draw

an auxiliary elevation on $X^1Y^1$ .

Figure 7 shows two orthographic views of a Location Bracket.

Using the information given, produce an isometric drawing of the bracket with 'X' as its lowest point. DO NOT COPY the views.
