1

A constant velocity (CV) joint is closely related to which of the following?

63% Answer Correctly

sprint joint

master cylinder

universal joint

ball joint


Solution

Like CV joints, universal joints (U-joints) are located at each end of a drive shaft and allow the shaft to operate at a variable angle with the item it is driving. Universal joints perform the same basic function as CV joints but CV joints have a wider range of operation.


2

The steering __________ transfers the motion of the steering gear output shaft to the steering arms that turn the wheels.

57% Answer Correctly

arms

linkage

cylinder

column


Solution

The steering linkage is a system of pivots and connecting parts between the steering gear and the control arms. The steering linkage transfers the motion of the steering gear output shaft to the steering arms that turn the wheels.


3

What links each piston to the engine's crankshaft?

72% Answer Correctly

piston ring

connecting rod

halfshaft

cylinder arm


Solution

A connecting rod employs a wrist pin to link each piston to the engine's crankshaft.


4

Which of the following is not a function of a car battery?

51% Answer Correctly

acts as an electrical reservoir for excessive current

delivers current to the ignition system to start the engine

acts as a supplemental source of energy to moderate engine performance

delivers supplemental current when the alternator can't handle high electrical system loads


Solution

The lead-acid battery is the core of the electrical system, providing current to the ignition system to start the engine as well as delivering supplemental current when the alternator can't handle high electrical system loads and acting as an electrical reservoir for excessive current.


5

Which engine stroke starts with the piston at top dead center?

61% Answer Correctly

exhaust stroke

intake stroke

compression stroke

power stroke


Solution

The four-stroke piston cycle of internal combustion engines starts with the piston at top of the cylinder head (top dead center or TDC) during the intake stroke. The piston moves downward in the cylinder creating a vacuum that pulls an air-fuel mix into the combustion chamber through the now open intake valve.
