Question 1: Name three common manual tools used for drawing straight lines and describe how each is used.

Answer: A ruler, a set square, and a T-square. A ruler is used to draw straight lines freehand; a set square helps draw precise angles, typically 30°, 45°, or 60°; a T-square is used to draw horizontal lines and to align other tools at right angles.

Question 2: Explain the purpose of a compass in manual drawing and how it is used.

Answer: A compass is used to draw circles or arcs. It consists of two arms: one with a point to anchor at the circle's center and the other with a pencil to draw the circumference. The width between the arms determines the radius.

Question 3: Identify two cutting tools used in manual graphics work and describe their main function.

Answer: A craft knife (e.g., a X-Acto knife) for precise cutting of paper or card; and scissors for cutting along straight or curved lines quickly and easily.

Question 4: Describe the safety precautions you should take when using manual cutting tools.

Answer: Always cut away from your body, use a cutting mat to protect surfaces, keep blades sharp to reduce force needed, and store tools safely when not in use.

Question 5: Sketch a basic design for a custom eraser suitable for fine detail work.

Answer: A small, rectangular eraser with a pointed tip for precision erasing and a flat side for larger areas. The sketch should show the shape and size suitable for detailed work.

Question 6: Draw a simple layout of a manual drawing board, labeling key features such as the surface, edge guide, and clamps.

Answer: A rectangular board with a smooth surface, a side edge with a sliding edge guide for aligning paper, and clamps at the sides to hold the paper securely.

Question 7: List four different types of manual pencils used in technical drawing and their typical uses.

Answer: H pencils (hard, for fine lines), B pencils (soft, for darker lines), HB (medium hardness, general purpose), 2H (harder, for fine, light lines).

Question 8: Explain why it is important to keep manual drawing tools clean and well-maintained.

Answer: Clean tools ensure accuracy in drawing, prevent damage to the tools, and extend their lifespan. Sharp blades provide cleaner cuts and lines.

Question 9: Sketch a hand grip for a manual craft knife that would provide good control during cutting.

Answer: The grip should be ergonomic, with a comfortable handle that fits well in the hand, possibly with textured surfaces for grip, and a secure hold to allow precise control.

Question 10: Identify and describe the function of a manual tool used for smoothing rough edges of cut materials.

Answer: A sanding block or fine abrasive paper, used to smooth edges and surfaces after cutting, ensuring a clean finish and removing splinters.
