Question

steering and suspension - final exam
this exam consists of 25 questions. answer each question.
two technicians are discussing types of coil springs.
technician a says that a progressive spring changes spring rate (stiffness) as it is compressed.
technician b says that a linear spring has a spring rate that does not change throughout its range.
who is correct?
technician b only.
both technicians a and b.
neither technician a or b.
technician a only.

Explanation:

To determine who is correct, we analyze the statements:

• A progressive spring has a spring rate (stiffness) that changes as it is compressed (e.g., the pitch between coils changes, so more force is needed as compression increases). So Technician A's statement is correct.
• A linear spring has a constant spring rate throughout its range (the relationship between force and compression is linear, \( F = kx \) where \( k \) is constant). So Technician B's statement is also correct.

Answer:

Both Technicians A and B.
