Terminology: Templates, Trusses & Welding Symbols is one of 9 topics in the Grade 11 Mechanical Technology CAPS syllabus, covered across 3 lessons on Study Vault. Below are real practice questions from this topic with full worked answers.
Sample practice questions
Easy
1. Which of these is a material commonly used to make a template?
Steel plate
Molten glass
Liquid coolant
Compressed gas
Answer: Steel plate — Templates are commonly made from wood, cardboard, steel plate or hardboard, with the choice depending on how many times the template will be reused.
Easy
2. Which theorem is used to accurately set out a right angle without relying on a protractor alone?
Pythagoras' theorem
Ohm's law
Hooke's law
The law of moments
Answer: Pythagoras' theorem — Pythagoras' theorem, using a triangle with sides in a known ratio such as 3:4:5, allows a right angle to be set out and checked accurately on the workshop floor or material.
Medium
3. Give the side ratio of a right-angled triangle commonly used to set out a right angle using Pythagoras' theorem (as three numbers separated by colons).
Answer: 3:4:5 — A triangle with sides in the ratio 3:4:5 satisfies Pythagoras' theorem (3 squared plus 4 squared equals 5 squared), so it reliably produces a right angle when marked out.
