Lectures and Notes – 2021b (Summer 2021)
MWF 8:00am – 9:10am
6/01/2021 to 08/11/2021
The Lectures are MP4 on Zoom. A password is given since they sent me one with the file, but I’m not sure they are needed.
Please also note that the links below will be blank until we have had the class and generate the materials.
| Class | Material covered if we can stick to the schedule. Time on video/Covered. Class start times are for last semester and will be updated when known. |
|
| Class 1 Wednesday 6/2/21 |
Class 01 starts 12:36 minutes into the video. How to use the syllabus, Statics, axial normal (tension ans compressive) and shear stresses Class notes 01 but SEE VIDEO below for use Access Password: PBmn=T6. |
|
| Class 2 Friday 6/04/21 |
Class 02 starts 1 hour 5 minutes into the video. More normal and shear stresses, bolt bearing stresses. Sigma = stress in an existing structure, Sigma Allowed = the stress permitted by the governing code written by experts on that material. Equations are used for analysis (what is the stress in an existing structure with a code load on it), to determine the allowed load in an existing structure, or to determine the required size for a planned structure (design)., Class notes 02 but SEE VIDEO below for use Access Password: RVZ6*!*^ |
