Chapter 18, Problem 18.28P

Interpretation Introduction

Interpretation:

Failure of the propeller shaft on a ship is to be explained.

Concept introduction:

• The endurance limit is the maximum stress below which steel can accept a number of cyclic loads before the failure.
• Corrosion is a chemical reaction occurring due to the reaction with atmospheric moisture and oxygen resulting in the formation of oxides.
• During fatigue testing, the maximum amount of stress applied to material for a number of stress cycles without failing isan endurance limit.
