3.1 Give ONE word/term for each of the following descriptions by choosing a word/term from the list - NSC Civil Technology Woodworking - Question 3 - 2019 - Paper 1

The term used to describe the component that closes the opening where the wall panel and the floor meet is 'skirting'.

To calculate the area of the roof underlay, use the formula: Area = length × width. Therefore, the area is: $ext{Area} = 2.5 ext{ m} imes 3 ext{ m} = 7.5 ext{ m}^2$.

The term for the intermediate vertical member that separates two casements in a double casement is 'mullion'.

To find the area of roof sheeting, first calculate the overall width and length of the roof:

• Overall Width = 150 mm + 8 000 mm + 150 mm = 8 300 mm
• The length of the roof sheeting can be derived from the length of the rafter plus overhang:

$ext{Length of sheet} = 2 900 ext{ mm} + 50 ext{ mm} = 2 950 ext{ mm}$

Convert dimensions to meters, calculate the area:

ext{Area} = rac{8.3 ext{ m} imes 2.95 ext{ m}}{1} = 48.97 ext{ m}^2.

To determine the number of ridge plates needed, use the formula:

ext{Number of ridge plates} = rac{ ext{Width of roof covering}}{ ext{Length of one ridge plate}}

• Given:
  • Width of roof covering = 8.3 m
  • Length of one ridge plate = 1.8 m

Thus,

ext{Number of ridge plates} = rac{8.3}{1.8} ext{ ridge plates} = 4.61 ext{ ridge plates}

Rounding up, 5 ridge plates are needed.

Sketch a vertical section through the top part of a wall panel. The sketch should clearly illustrate the connection between the ceiling and the wall, along with any relevant dimensions and proportions.

Complete the drawing of the built-in cupboard framework. Include the specified components such as shelves and drawers in proportion, ensuring dimensions are accurately represented.
