Sec occurs when equipment is exposed to environments
Sec occurs when equipment is exposed to environments conducive to certain cracking mechanisms. This means that specific environmental conditions must be present to promote the cracking mechanisms, such as stress corrosion cracking (SCC). Therefore, the correct option is 'Conducive to certain cracking mechanisms.'
Likely typo in question, should be "SCC"
Jum no idea
SCC, stress corrosion cracking, requires both a chemical corrosion mechanism weakening the material and a mechanical stress to break (aka crack) it. This question is strangely worded, but the answer should likely be C, as chemical cracking would happen first.
