About This Quiz

What do you call four bicycle tires strapped to seat, a tiller, a frame, and an ethanol-burning two-cylinder engine? If you're Henry Ford and it's the late 1800s, you call it a quadricycle. That was the first car Ford ever made, and it was mostly spare parts from the sound of things. Fast forward to today, and it takes 30,000 separate parts to make a car, according to Toyota's website. That's everything from the hood, the side panels and the engine block down to each individual screw that might be holding down some door panels inside or in the hinge of the visor. 30,000!  How many of them do you think you could name if you were pressed?

Everyone knows a tire when they see one, or a steering wheel, but do you know what a starter solenoid looks like? What about a heat shield? Or a flywheel in a manual car's clutch assembly? Some car parts are super obvious, and some are less obvious. If you know you have the skills to make the grade, show us your stuff by picking out some connecting rods and gudgeon pins. If you can manage this entire list, you just might be an automotive expert.

This part generates down force to keep the car on the road. What is it?
Crank case
Kingpin
Differential
Spoiler
Correct Answer
Wrong Answer

While most cars don't need a spoiler and they're just there for aesthetics, the point of the wing-style spoilers is to work like an airplane wing in reverse, creating a down force that keeps the car on the road without adding weight. Smaller spoilers, as opposed to wings, are supposed to make the car more aerodynamic, but some of them actually do the opposite.

Which of these parts converts kinetic energy into heat?
Rocker arm
Strut
Shock absorber
Pinion
Correct Answer
Wrong Answer

Not everyone is aware of the physics behind a shock absorber, but they take all that bumping and rattling and motion (the kinetic energy of your car moving) and absorb it as the name suggests, but they're changing it into heat. That heat is then dissipated; it's usually in oil, but in some fancy shocks, there will be things like nitrogen to help the job.
