thanks bob. I really appreciate your help.

Of course, I'd be happy to help you find some good sources on the topic of stress, strain, Young's modulus of elasticity, and shearing stress. Here's a step-by-step guide on how you can find reliable sources:

1. Start with a general search engine: Begin by using a search engine like Google, Bing, or Yahoo. Enter relevant keywords, such as "stress and strain," "Young's modulus of elasticity," or "shearing stress." Enclose the keywords in quotation marks to ensure more accurate results.

2. Use trusted educational websites: Look for reputable educational websites such as universities, academic institutions, or government websites. To narrow down your search results, add the term "site:.edu" or "site:.gov" to your search query. For example, you could search for "Young's modulus of elasticity site:.edu" to find educational sources specifically discussing that topic.

3. Utilize online libraries and databases: Access online libraries and databases that provide scholarly articles and research papers. Some popular platforms include Google Scholar, IEEE Xplore, JSTOR, and ScienceDirect. Enter your keywords and explore the search results to find relevant and reputable sources.

4. Check books and textbooks: If you prefer more in-depth information, consider looking for books or textbooks on the subject. Visit your local library or check online platforms like Amazon or Google Books. Search for titles specifically related to stress, strain, elasticity, or materials engineering.

5. Review scientific journals: Peer-reviewed scientific journals are excellent sources for academic information. Many journals offer free access to some of their articles, while others may require a subscription. Look for journals related to materials science, mechanical engineering, or physics that cover the specific topics you are interested in.

6. Evaluate the sources: Once you have found potential sources, it is essential to evaluate their credibility. Check if the author is an expert in the field, the publication date to ensure you're getting up-to-date information, and if the source is from a reputable institution or publisher. Additionally, read the abstract or summary to determine if the content aligns with your needs.

Remember, it's always beneficial to cross-reference multiple sources to obtain a well-rounded understanding of the subject.
