What is Technology?

Technology is the application of scientific knowledge to solve human problems and improve lives. It involves using tools, materials, skills, and knowledge to design and create products.

The Technological Process

  1. Identify the problem
  2. Gather information
  3. Generate ideas/solutions
  4. Choose the best solution
  5. Build/make a prototype
  6. Test and evaluate
  7. Communicate results

Technical Drawing

Technical drawing (engineering drawing) is the language of designers and engineers. It uses standard symbols, lines, and scales to communicate how objects are built.

Types of Drawing

TypeDescription
Freehand sketchQuick, rough drawing without instruments
Orthographic projectionShows front, side, and top views (2D)
Isometric drawing3D-looking drawing on a grid
Perspective drawingShows depth as the eye sees it

Drawing Instruments

  • Drawing board and T-square
  • Set squares (45° and 60°/30°)
  • Compass and dividers
  • Protractor
  • Drawing pencils (HB, 2H)

Types of Lines in Technical Drawing

  • Continuous thick: visible outlines
  • Continuous thin: dimensions, leader lines
  • Dashed: hidden edges
  • Chain dot: centre lines

Question 1 of 5
Technology is best defined as:
Technology involves applying scientific knowledge to design, create, and use tools and systems that solve problems and improve the quality of human life.
Question 2 of 5
In technical drawing, a dashed line represents:
Dashed (hidden) lines show edges and features that are present but cannot be seen from the viewing direction — they are hidden beneath the surface.
Question 3 of 5
Which drawing shows the front, top, and side views of an object?
Orthographic projection shows multiple 2D views (front, top/plan, side) of an object, giving complete information about its shape and size.
Question 4 of 5
What is the FIRST step in the technological process?
The technological process always begins with identifying or defining the problem that needs to be solved.
Question 5 of 5
A T-square is used in technical drawing to:
A T-square slides along the edge of a drawing board, allowing the draftsman to draw accurate horizontal lines and to guide set squares for vertical and angular lines.
