FIGURE 3.1 below shows the external elevation of a casement within a frame - NSC Civil Technology Woodworking - Question 3 - 2023 - Paper 1

A is the frame head, B is the bottom rail of the fanlight, and C refers to the frame stiles or jambs.

A is the wall paneling board, B is the horizontal rough ground, C is the skirting, and D is the quadrant mould or quarter round.

The function of B (horizontal rough ground) is to provide a solid base that supports the wall paneling above and creates a smooth surface for the floor covering to be laid over.

The material used for part C (skirting) is typically wood or timber.

To calculate the area of roof tiles needed, use the formula:

$ext{Area} = ext{Length} imes ext{Width}$

Given the length of the roof as 8 740 mm and the width based on the spacing of the trusses:

Area = 8 740 mm x (Length of supporting part)

Also, considering the length of a rafter with overhang: 3 600 mm + 50 mm = 3 650 mm

Final Area calculation gives approximately 63.8 m², rounded off to 63.8 m².

To determine the number of roof trusses needed:

1. Calculate the internal dimension which is 8 000 mm.
2. Determine the centre-to-centre spacing which is 500 mm.

Using the formula:

ext{Number of Trusses} = rac{ ext{Width}}{ ext{Spacing}} + 1

This gives: Number of Trusses = ( \frac{8 000 mm}{500 mm} + 1 = 16 + 1 = 17 ) trusses.

The front view of the cupboard should reflect:

• One bottom drawer with a handle.
• Four shelf spaces labeled clearly, with accurate proportions for the sides, top, and kick plate/base.
• Ensure correct scaling and dimensions are used as indicated on the answer sheet.
