Question

post-test which of the following hinges are used on vehicle doors and are adjustable? a. weld - on hinges b. bolt - on hinges c. pivot hinges d. concealed hinges

Explanation:

• Weld - on hinges: Once welded, they are not easily adjustable as the welding process fixes them in place.
• Bolt - on hinges: These can be adjusted by loosening the bolts, re - positioning the door (or the attached part) and then tightening the bolts again. This makes them suitable for vehicle doors where adjustments might be needed during installation or due to wear over time.
• Pivot hinges: Typically used in applications like gates or some types of furniture. They are not as commonly associated with vehicle door adjustments.
• Concealed hinges: Are more about a sleek appearance (as they are hidden) rather than adjustability for vehicle doors.

Answer:

B. Bolt - on hinges
