(ii) Pointed /conical —+ for general purpose e.g. lettering and outlines.

(b) Advantages of plywood over solid timber

  • It is stronger.
  • It can be shaped by folding into intricate shapes.
  • It is available in large sheets.
  • Does not require planning

    (i) Material

  • Availability
  • Workability
  • Cost
  • Suitability
  • Safety
  • durability

    (ii) Proportion

  • Aesthetics
  • Application
  • Use-ability
  • Ergonomics

    4. Drawing with the correct dimensions

    1 mark Any 6 dimensions 6x1/2=3 marks

    5. (a) Reasons for care when storing drawing instruments.

  • To preserve their accuracy.
  • To avoid breakages that may be occur.
  • For durability thus reducing the cost of replacement.
  • To prevent deformation

    (b) Components of a computer

  • Monitor — Displays information to the user.
  • CPU — It is the central processing unit where processing of data and information takes place.
  • Mouse — It is used for selecting, pointing, and highlighting.
  • Keyboard — It is used for capturing and entering numeric and alphabetical commands.


    8. (a) The accuracy of the scale is 0.01 m (1cm) Reading ‘P’

    - Main reading 1.50m
