Stress, Strain, and Elasticity (Part 1)

In these three videos, I teach axial and shear stress, deformation, strain, and elasticity moduli.

when you're describing the shear strain, you say that : "A" is the cross-sectional area of the rod.. isn't A supposed to be twice of that because it's attached on both sides?

@eenasomari

No, it isn't. For a comparison, thing about axial strain on a cylinder. A compressive force would be acting on both ends of the cylinder, but it would only be counted once. Similarly, you only count the cross-sectional area once in your computations for shear stress.

Thanks for your reply.

Which Bamboo Tablet did you get and is your's top of the line for your needs?

Request to know what software ______________you are using here and what graphs tablet_________?

@ChuckBoldwyn

For screen recording I use either Hypercam2 or Camtasia Studios 7

For graphics I use Paint in most videos, Photoshop CS5 in some others

In this video and most of my early ones, I am writing/drawing just with my mouse. Later, I use a Bamboo Pen and Touch Tablet. Their tablets are great and inexpesive; you can find them at any Best Buy (just be careful you get the right kind for your needs).

Very Helpful. I suggest you make an outline of what you plan to say to better organize your video.

Wow... this guy is REALLY struggling... is this a T.A.'s video? He sounds confused about his own material...

The video did help my understanding of stresses, strains and elasticity. but your lack of examples made me laugh. Otherwise good video :)
