Systems & Control: Drives & Screw Threads is one of 8 topics in the Grade 10 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 drive system transmits motion through direct tooth-to-tooth contact between two parallel shafts?
Spur gears
Pulleys and belt drives
Chain drives
None of these use direct contact
Answer: Spur gears — Spur gears are toothed wheels that mesh directly together, transmitting motion through direct tooth-to-tooth contact between two parallel shafts.
Easy
2. Which drive system uses a belt running over two or more pulleys, transmitting motion through friction?
Pulleys and belt drives
Spur gears
Chain drives
None of these use friction
Answer: Pulleys and belt drives — A pulley and belt drive uses a belt running over two or more pulleys, transmitting motion by gripping the pulleys through friction rather than a rigid mechanical connection.
Medium
3. Name the drive system that uses a roller chain engaging with toothed sprockets, giving no-slip transmission over a greater shaft distance than a gear pair typically achieves.
Answer: a chain drive — A chain drive uses a roller chain engaging with toothed sprockets, positively engaging like a gear (no slip) while spanning distance like a belt.
