Wheels 1

Imagine Alexander, James, and George are in a car race. Alexander has a car with alloy wheels, while James and George have cars with steel wheels. What distinguishes the wheel nuts used for Alexander's alloy wheels from those used for James and George's steel wheels?

• The wheel nuts for Alexander's alloy wheels are generally smaller than those for James and George's steel wheels

• The wheel nuts for Alexander's alloy wheels often have a rotating steel sleeve or washer

• A spring washer has to be used with the wheel nuts on Alexander's alloy wheel

• A central wing nut is always used on Alexander's alloy wheels

Amelia, Anaya, and Isabella are working on a project involving an interference fit wheel stud. They are having a debate about part X in the diagram. Can you help them identify it?

• Hub

• Knurled section

• End flange

• Threaded section

• Wheel nut

Rohan and Ava are working on a project to build a model car. They are fitting twin wheels to single hubs. They are wondering what they often use a wheel nut in conjunction with. Can you help them out, Evie?

• a thrust washer.

• roller bearings.

• alloy spacers.

• a conical washer.

Ava, Anaya, and Kiara are participating in a car race. They are given a choice to pick a wheel for their cars. Which type of wheel should they choose if they want to use a wing nut?

• Alloy

• Twin

• Wire

Imagine Benjamin, Scarlett, and Ishaan are working on a car project. They are debating whether to use tapered nuts or bolts when fitting the wheel to the vehicle, as they believe it helps to centre the wheel on the hub. Is their belief correct?

• Yes

• No

Imagine Chloe, Grace, and Ishaan are building a car for their science project. They are debating about the primary function of the wheel hub. Can you help them out?

• Chloe thinks it's to hold the wheel in place

• Grace believes it's to provide a surface for the wheel to rotate on

• Ishaan says it's to distribute the weight of the vehicle

• Or, are all of them correct?

Sophia, Evie, and Anaya are working on a car for their school project. They come across a knurled section on a wheel stud. Can you help them figure out what is the purpose of this knurled section?

• To provide a grip for the wheel nut

• To prevent the wheel from slipping

• To allow for easy installation and removal of the wheel

• To protect the stud from wear and tear

Imagine Ella, Muhammad, and Samuel are in a car race. They all have the same car model, but Ella's car has alloy wheels while Muhammad and Samuel's cars have steel wheels. Why might Ella have an advantage?

• Her alloy wheels are more durable

• Her alloy wheels are lighter and improve vehicle performance

• Her alloy wheels are cheaper

• Her alloy wheels require less maintenance

Max, Elsie, and Florence are building a car for their science project. They are debating about the main purpose of the wheel bearing in their model car. Can you help them out?

• To reduce friction between the wheel and the axle

• To hold the wheel in place

• To distribute the weight of the vehicle

• All of the above

Oscar, Noah, and Ella are building a race car for their school project. They are debating about the function of the wheel nuts in their car's wheel assembly. Can you help them out?

• To secure the wheel to the hub

• To provide a grip for the wheel

• To allow for easy installation and removal of the wheel

• To protect the wheel from wear and tear
