The right front wheel of your front-wheel drive car drops into a pothole and the left front wheel doesn't lose contact with the road. Which of the following is true?
your car has an independent front suspension |
|
your car has an independent rear suspension |
|
your car has a rigid axle front suspension |
|
your car has a rigid axle rear suspension |
An independent suspension allows the wheels on either side of an axle to move independently from each other. The fact that the left front wheel didn't move up in response to the right front wheel moving down is evidence of this.
Engines with radial cylinder configurations are most common in:
tank engines |
|
train engines |
|
heavy truck engines |
|
aircraft engines |
A radial arrangement places cylinders in a circle around the crankshaft and is used almost exclusively in aircraft engines.
Which of the following regulates the flow of coolant through the radiator?
crankshaft |
|
water jacket |
|
thermostat |
|
water pump |
The thermostat controls coolant (and, through it, engine) temperature by regulating the flow of coolant through the radiator. A bypass tube allows coolant to bypass the radiator and flow back into the water pump when its temperature is low enough that the thermostat is closed.
What is the large casing that contains the cylinders and many of the internal components of the engine?
engine block |
|
manifold |
|
transmission |
|
chassis |
The engine (or cylinder) block is the large casing that contains the cylinders and many of the internal components of the engine.
Which of the following transfers the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension?
control arms |
|
springs |
|
constant velocity (CV) joint |
|
transfer case |
Constant velocity (CV) joints are located at both ends of a half shaft and their purpose is to transfer the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension. The inner CV joint connects the shaft to the transmission and the outer CV joint connects the shaft to the wheel.
