Mohrs Stress Circle.wmv

How to draw Mohr's Circle for a 2D complex stress element. Also sketching principal stress element, max shear element and an element at a known angle.
Correction - Very last arrow on Video +60MPa should point away for element (not towards it)
These note are used as part of a Diploma/degree in Mechanical Engineering.

great video! in the last 5 seconds, you mention that there is a stress of +60MPa in the normal direction, but you draw an arrow for compressive stress. is that correct, or is that meant to be tensile stress?

thanks for the video!

@deathcount24891 HI. You are correct. I stuffed that up. The very last arrow drawn should point away from the element. Thanks for pointing that out. Steve

lol, nvm u fix it later on.. thank you!!

[abkahvegi]

you may have made a mistake in min 12:45... its (-20, 55) not +20!??
