Доцент Цветков (МГСУ) проводит консультацию для ПГС: простые и сложные задачи по техмеху за 2 часа!

Covered: 1. What to consider when constructing Q and M diagrams; 2. Calculating bending strength using normal stresses: selecting a section from an I-beam, beam, or log. Strength testing. 3. Plotting a normal stress diagram; 4. Checking strength using shear stresses. Plotting a shear stress diagram; 5. Investigating the stress state during bending; 6. Principal stresses during bending; 7. Sections asymmetrical about the horizontal axis during bending. 8. How to show the effect of internal forces during bending and axial tension (compression) on a member; 9. How to calculate normal and shear stresses at an arbitrary point in a beam section and show them on an elementary area; 10. Axial tension (compression) of a member; 11. Determining the geometric characteristics of bar sections. Video links: a playlist with detailed construction of internal force diagrams; construction of diagrams for axial tension (compression); strength calculations for axial tension (compression); determining the geometric characteristics of a section; investigating the stress-strain state; and exam problems in technical mechanics (without calculation models).
