LV04q practice

Imagine you are designing a vehicle and need to choose a steering mechanism. Which of the following would you consider?

• Ackermann steering

• Peg and Ball

• Crown wheel and pinion

• Rack and pinion

Imagine you're taking your car, a 2010 Audi A4 3.0 tdi quattro, for its annual MOT test. The mechanic informs you that to pass, the minimum braking efficiency for the footbrake must not be:

• less than 16%

• less than 25%

• less than 50%

• less than 75%

Imagine you're preparing your car for a long road trip. In the process of checking and adjusting the front wheel alignment, which of the following statements is NOT true?

• Adjustments must be made equally to both track rods

• You should remove any very heavy loads from the trunk before making adjustments

• You should check the tyre pressures are correct before making any adjustments

• Buckled wheels will not affect the wheel alignment

Imagine you're driving your car and you notice an issue. If an offside brake caliper piston seized in the off position, this may cause the:

• vehicle to pull to the right when accelerating

• vehicle to pull to the right when braking

• vehicle to pull to the left when accelerating

• vehicle to pull to the left when braking

Imagine you're driving a sports car on a curvy mountain road. 'Oversteer' occurs when the:

• slip angles of the rear tyres are smaller than the slip angles of the front tyres

• slip angles of the rear tyres are larger than the slip angles of the front tyres

• slip angles of the front tyres are the same as the slip angles of the rear tyres

• rear wheels of a vehicle are carrying much less load than the front wheels

John notices his car's steering wheel begins to 'shimmy' more noticeably as he accelerates on the highway. This issue is most likely due to:

• tyre pressures are too high

• front wheels need balancing

• wheel alignment needs adjusting

• shock absorbers need replacing

When a car equipped with Ackermann steering geometry takes a sharp turn, it results in:

• toe-out of the front wheels during cornering

• understeer of the front wheels during cornering

• oversteer of the front wheels during cornering

• centre point steering on the front wheels

John notices that his car veers to the left when he applies the brakes. What could be causing this issue?

• the front wheel alignment is off, with too much toe-in

• the brake servo is malfunctioning due to a damaged induction manifold pipe

• the front brake caliper pistons on the driver's side are stuck

• the front brake caliper pistons on the passenger's side are stuck

John is checking his car before a long trip and remembers the legal limit for a car tyre tread depth is:

• 1.6 mm across 75% of the tyre width

• 1 mm across 100% of the tyre width

• 1.6 mm across the central 75% of the tyre width

• 1.6 mm across 100% of the tyre width

When a ship moves vertically at the front then the back in turn due to waves, this motion is called:

• roll

• bounce

• pitch

• sway
