Automotive & Shop Practice Quiz – Part 1
1. What do shock absorbers on a car connect the axle to?
Correct Answer: B) Frame of the car
Shock absorbers link the axle to the car frame to absorb bumps and keep the body stable while driving.
2. Where does combustion take place in a car?
Correct Answer: B) Cylinder
The fuel and air mix is ignited inside the engine cylinder, producing the power that moves the piston.
3. What does the radiator in a car do?
Correct Answer: B) Cools engine coolant
The radiator transfers heat from hot engine coolant to the air so the engine stays at the correct temperature.
4. What part of the engine do piston rings belong to?
Correct Answer: C) Pistons
Piston rings fit around the pistons to seal the combustion chamber and control oil consumption.
5. The catalytic converter is part of which system?
Correct Answer: B) Exhaust
The catalytic converter sits in the exhaust system and reduces harmful gases before they leave the tailpipe.
6. If a car is mostly driven in the city and the spark plug tip never gets hot enough, what might happen?
Correct Answer: B) Spark plug will foul
Short, slow trips prevent the plug from reaching self-cleaning temperatures, causing deposits that foul it.
7. Which tool is used to smooth rough wood surfaces?
Correct Answer: B) Sanding block
A sanding block evens out rough grain and prepares wood for finishing or painting.
8. What is a C-clamp used for?
Correct Answer: B) Holding objects together
C-clamps tightly secure workpieces during gluing, cutting, or assembly.
9. Which saw is best for making rough cuts with the grain of thick wood?
Correct Answer: C) Rip saw
A rip saw has coarse teeth designed to cut along the wood grain quickly.
10. What are piston rings designed to do?
Correct Answer: A) Seal combustion chamber
Piston rings seal the gap between piston and cylinder to keep combustion gases in and oil out.
11. Which of the following is NOT part of a vehicle’s electrical system?
Correct Answer: C) Fuel pump
The fuel pump belongs to the fuel system, not the core electrical components like battery or starter.
12. Which tool is best suited for turning bolts and nuts?
Correct Answer: C) Wrench
Wrenches are made to grip and apply torque to bolts and nuts for tightening or loosening.
13. What is the primary function of the transmission in a car?
Correct Answer: C) Change engine speed and torque
The transmission adjusts engine output to the right speed and torque for the wheels.
14. What type of wrench adjusts to multiple sizes?
Correct Answer: C) Adjustable wrench
An adjustable wrench has a movable jaw so one tool fits different nut and bolt sizes.
15. What does “torque” refer to in automotive terms?
Correct Answer: B) Force causing rotation
Torque is the twisting force that turns shafts, wheels, and fasteners.
16. In wood and metal shop practices, what is the use of a file?
Correct Answer: B) Smoothing rough edges
Files remove small amounts of material to shape or smooth edges and surfaces.
17. What type of fluid is typically used in hydraulic brakes?
Correct Answer: B) Brake fluid
Brake fluid transfers force through the brake lines to activate the braking system.
18. Which tool measures electrical current?
Correct Answer: B) Ammeter
An ammeter displays current in amperes so you can check electrical flow in a circuit.
19. The clutch in a vehicle is used to?
Correct Answer: B) Engage/disengage engine from transmission
The clutch lets the driver temporarily separate the engine from the transmission to change gears.
20. What is the main purpose of a torque wrench?
Correct Answer: A) Measure/apply specific torque to fastener
Torque wrenches ensure bolts are tightened to the correct torque to avoid failure or damage.
