Choose the correct statement. -A vehicle starting from rest needs less torque. -The lower the gear selected, the lower the output torque transmitted. -An automatic transmission uses a torque converter instead of a clutch. -The driveshaft divides the torque to the axles.

An automatic transmission uses a torque converter instead of a clutch.

Tech A says that gasoline is energy in chemical form. Tech B says that chemical energy is converted to mechanical energy by the combustion process of an engine. Who is correct?

Both A and B

Which of the following statements is true? Both live and dead axles drive the vehicle. Both live and dead axles support the weight of the vehicle. The dead axles use the engine's torque to turn the wheels. The lazy axles use the engine's torque to turn the wheels.

Both live and dead axles support the weight of the vehicle.

Which of these does not define the drivetrain layout? Engine position Engine capacity Engine orientation Number of driven axles

Which vehicles can switch from two-wheel to four-wheel drive by engaging the transfer case attached to the transmission? Front-wheel drive All-wheel drive Rear-wheel drive Four-wheel drive

Four-wheel drive

Which of these systems creates and delivers high voltage sparks at the right time to ignite the air-fuel mixture in the combustion chamber? Emission system SRS system TPMS system Ignition system

Ignition system

Tech A says that a piston engine has a roughly triangular shaped rotor. Tech B says that V engines have horizontally opposed cylinders. Who is correct?

Neither A nor B

Tech A says that a live axle is an axle that drives the vehicle. Tech B says that a dead axle means that the axle can be steered. Who is correct?

Tech A

Tech A says that one advantage of a mid-engine design is better weight distribution. Tech B says that the rear-engine design is commonly used in four-wheel drive vehicles. Who is correct?

Tech A

Tech A says that the gear ratios in the transmission give the vehicle an extended operating range. Tech B says that the final drive assembly has various gear ratios that can be selected with a gearshift lever. Who is correct?

Tech A

Tech A says that an SUV is typically a two-door convertible vehicle. Tech B says that many pickups come in two-door and four-door versions. Who is correct?

Tech B

Tech A says that most vehicles today are built with a ladder frame. Tech B says that most vehicles today do not have a full frame. Who is correct?

Tech B

Tech A says that pushing on the brake pedal stops the vehicle by converting chemical energy into thermal energy. Tech B says that brake pedal pressure is transmitted to the brakes hydraulically. Who is correct?

Tech B

Tech A says that the definition of torque is how far the crankshaft twists in degrees. Tech B says that torque can relate to tightness of bolts. Who is correct?

Tech B

Tech A says that the purpose of the battery is to charge the vehicle. Tech B says that in-line engines are generally easier to work on than V engines. Who is correct?

Tech B

Which of the following is true of a horizontally opposed configuration? -The pistons are in two banks on both sides of a common crankshaft. -The pistons are in two banks on opposite sides, forming a deep V with a common crankshaft at the base of the V. -The pistons are in one bank, but form a shallow V within the bank. -The pistons are in two VR banks in a deep V configuration with each other.

The pistons are in two banks on both sides of a common crankshaft.

All of the statements below are true except: Torque twists the gears in the transmission. Torque twists the gears in the final drive assembly. Torque turns the axles. Torque pushes the piston down.

Torque pushes the piston down.

Which of these components multiples the torque from the engine by running it through a number of different gear ratios? Steering Suspension Transmission Piston

Transmission
