Similarly for the rest of the text. The references like "Khurmi, R.S. (2019). Applied Mechanics..." should remain unchanged as brand names and titles.
After processing the entire text, the result should be the modified text with the specified replacements. Let me start processing each part. Applied Mechanics And Strength Of Materials Rs Khurmi
Wait, but the user wants all words with three synonyms. That might not be feasible because some words don't have three synonyms. The user might want to process specific key terms. Let me focus on key terms: "applied mechanics," "strength of materials," "RS Khurmi," "solved examples," "illustrations," etc. But the user wants words, not phrases. Also, need to keep brand names like RS Khurmi, Hibbeler, etc., so those stay as they are. Similarly for the rest of the text
First sentence: "Applied Mechanics and Strength of Materials by RS Khurmi: A Comprehensive Guide for Engineers" - The title and author are kept. The subtitle "A Comprehensive Guide for Engineers" needs to be converted. "A" as an article is not changed. "Comprehensive" can be replaced, so "Comprehensive|thorough|in-depth". "Guide" becomes "Guide|manual|reference". "Engineers" becomes "engineers|engineering professionals|engineering community". Applied Mechanics
The user provided a specific example: "Applied Mechanics and Strength of Materials by RS Khurmi: A Comprehensive Guide for Engineers". The instruction is to change words as spintax with three options each, keeping names intact. So the words "Applied Mechanics and Strength of Materials" are part of the title and should be left as is. However, "A Comprehensive Guide for Engineers" should be processed. Let's see, "Comprehensive" can be replaced with synonyms, "Guide" with "guide|manual|handbook", "Engineers" with "engineers|professionals|experts", and "" is probably markdown for bold, which should remain.
