Question

Tech a says that the maximum cylinder bore or liner wear occurs at the top of the ring travel area. tech b says the bore or liner wear is normally uniform from the top to the bottom of the cylinder. Which of the following statements is true? 1) Only tech a is correct. 2) Only tech b is correct. 3) Both tech a and tech b are correct. 4) Neither tech a nor tech b is correct.

Answer 1

Tech A's claim that maximum cylinder bore or liner wear occurs at the top of the ring travel area is accurate due to the usual conditions encountered in this area. Tech B's statement, suggesting uniform wear from top to bottom, is less accurate as wear tends to reduce lower in the cylinder.

Step-by-step explanation:

In regards to wear in a cylinder, Tech A is accurate. The maximum bore or liner wear typically appears at the top of the ring travel area. This wear primarily takes place due to high temperature, pressure, and mechanical stress. Contrarily, the claim made by Tech B, arguing wear is uniform from the top to the bottom of a cylinder, is generally inaccurate. Wear can differ significantly along the height of a cylinder, often lower at the bottom due to less exposure to stressful conditions.
