Question 1

Which of the following tools is specifically designed to measure a very small gap or clearance between two parts, such as a spark plug gap?

Accepted Answer

A feeler gauge

Answer

A feeler gauge is a tool consisting of several small lengths of steel of different, calibrated thicknesses. It is used by inserting the blades into a gap until a slight drag is felt, allowing for a precise measurement of the clearance.

Question 2

In a standard four-stroke internal combustion engine, what is the correct sequence of strokes?

Accepted Answer

Intake, Compression, Power, Exhaust

Answer

The cycle begins with the Intake stroke, drawing in the fuel-air mixture. This is followed by the Compression stroke, then the Power stroke where ignition occurs, and finally the Exhaust stroke to expel the burnt gases. A common mnemonic is 'Suck, Squeeze, Bang, Blow'.

Question 3

What is the primary purpose of a torque wrench?

Accepted Answer

To apply a precise amount of rotational force

Answer

A torque wrench is a precision tool that allows a user to apply a specific, measured amount of rotational force (torque) to a fastener. This is critical for safety and performance, as it prevents under-tightening or over-tightening bolts on components like wheels and engine parts.

Question 4

Before drilling a hole in a piece of metal, it is best practice to use a center punch to:

Accepted Answer

Create a guide dimple for the drill bit

Answer

Using a center punch creates a small indentation in the metal surface. This dimple provides a starting point for the drill bit, preventing it from 'walking' or wandering across the surface and ensuring the hole is drilled in the precise location.

Question 5

What is the function of a car's radiator?

Accepted Answer

To dissipate heat from the engine coolant

Answer

The radiator is a key component of the engine's cooling system. Hot coolant from the engine flows through the radiator's thin tubes, where airflow (from driving or a fan) dissipates the heat before the cooled fluid is circulated back to the engine.
