On the J rim shown, which parts are highlighted in yellow?

German

Lug bolts are most commonly found on ___ cars.

flange

On the J rim shown, which parts are highlighted in yellow

lug bolt

Which type of fastener is shown in the graphic?

20 threads per inch

On the stud shown, if the measurement is ½ inch x 20, what does the 20 stand for?

true

On hub-centric wheels, the center bore should be an exact match for the hub.

false

The mounting surface on a wheel with a +40mm offset is 40 millimeters towards the back side of the wheel when measured from the centerline.

Acura, Honda

Ball seats are commonly used on wheels for which car models?

Transition area

Which part of the rim is an angled ledge that extends to the bottom of the center well?

inches

On a wheel, backspace is measured in what?

mag

What type of seat do the bolt holes on this wheel have?

1 in = 25.4mm

The conversion formula for inches to millimeters is:

rwd

The type of vehicle position on this lift is:

fwd

The type of vehicle position on this lift is:

2500

A 10,000-pound lift would be capable of supporting ___ pounds of each arm.

vehicle lift point

What does the triangle in the image mean?

false

Because of their simple construction, it is not necessary to inspect floor jacks and jack stands before each use.

true

The ALI Lift Point Guide provides the lift points of different vehicles by year, make and model

2500

If a two-post above-ground lift has a maximum lifting capacity of 10,000 pounds , what is the maximum lifting capacity of each arm?

under driver’s seat

On a two-post above-ground lift with asymmetrical arms, the lift towers must be positioned at the vehicle’s center of gravity. Where would this be on a four-wheel drive SUV?

No

Does the lift pad in the photo appear to be properly placed?

false

It is acceptable to use a jack stand under a vehicle as a stop in case the floor jack fails.

torque

The measure of twisting force on lug nut or bolt

clamping force

the physical property that presses the wheel against the end of the axel and is ultimately the result of bolt tension

yield point

The point where clamping force exceeds the limits

true

In the laboratory test, when the stud and nut were in good condition, the recommended torque resulted in the proper amount of clamping force

false

In the laboratory test, as the torque reading got higher, the difference in clamping force at each torque level remained the same as the clamping force did not increase significantly, indicating a lack of proper torque application.

false

In the laboratory test, when a lubricant was added to the stud, the relationship between torque and clamping force remained the same

true

All published lug nut torque specifications are assumed to be dry unless specific lubricants are named with “oiled” torque values

Newton meters

Torque is measured in both foot pounds and:

loses tension

When a stud is stretched beyond the yield point, it:

180

A 180-pound man applying all of his weight to a one-foot breaker bar will generate ___ foot pounds of torque

amount of force

When force is applied to a breaker bar, the torque can be calculated by multiplying the length of the lever by the: amount of force applied.

clamping force

The physical property that presses the wheel against the end of the axle

320

If a 160-pound man is using a 2-foot lever to tighten lug nuts, what is the torque being applied

torque

The measurement of twisting force on a lug nut or bolt is called:

true

Joint settling is the leading cause of loose wheels

true

All published lug nut torque specifications are assumed to be dry

false

Over-tightening lug nuts is the best way to ensure a proper fit for the wheel
