A triangle ABC has a base AB = 90 mm, side AC = 80 mm and angle BAC = $75^\circ$. (a) Construct the triangle ABC. (b) Construct a triangle XYZ similar to triangle ABC, and with a perimeter of 240 mm.

Figure 2 shows a simple mechanism with point O fixed, while point B is free to slide along the bar XY as OA rotates in a clockwise direction as shown.

(a) Copy the given mechanism. (b) Plot the locus of the point P, as OA makes one complete revolution.

Figure 3 shows the front elevation and plan of an I-shaped bar.

Draw (a) the given front elevation and plan (b) an auxiliary elevation of the bar on the XY line.

Figure 4 shows two orthographic views of a truncated right rectangular prism.

Draw full size (a) the two given views (b) the development of the truncated right rectangular prism with $C_1C_1$ as the seam.

Figure 5 shows two incomplete orthographic views of a cylinder intersecting a hexagonal prism at $60^\circ$.

(a) Draw the given elevations. (b) Complete the elevation showing the curve of interpenetration between the hexagonal prism and the cylinder. (c) Complete the plan showing the curve for the end of the cylinder.

Figure 6 shows the orthographic views of a WOODEN BLOCK.

Draw an isometric view of the block with 'S' as its lowest point.
