It sounds like you're looking for the solutions manual for Mechanics of Materials, 8th Edition (likely by Beer, Johnston, DeWolf, & Mazurek).

The 8th edition emphasizes a specific methodology to help you tackle problems more effectively :

8) Validate numerical solutions

• Cross-check results using simple computational tools (spreadsheet, Python, MATLAB). For common beam problems, small scripts can reproduce shear/moment and stress distributions.
• Dimensional analysis and limit checks catch sign or scaling errors.
