Study Notes
First Aid and Safety
- To stop bleeding in an injured person, apply ointment, pressure over the wound, tie a bandage, and apply tincture over the wound.
- Occupational safety and health safety are important topics to be taught in each semester.
Drawing Instruments and Equipments
- A helmet is a mandatory symbol for safety equipment.
- To draw circles of more than 150 mm radius, a large-size divider or a large-size compass is used.
- To divide a circle into any number of equal angular parts, a protractor, set-square, compass, or French curve is used.
Types of Lines and Angles
- Horizontal lines are perpendicular to vertical lines.
- Two graphic entities that are at a constant distance apart along the length refer to parallelism.
- A uniformity refers to two graphic entities that are identical in shape and size.
- A line drawn as long dashed dotted narrow line is a centre line.
- A line drawn as continuous narrow freehand lines is a visible edge or a limit of partial or interrupted views.
Triangles
- If the sides of a triangle are unequal, it is a scalene triangle.
Drawing Instruments and Equipments (again)
