I've been taught this concept many times, but this was the best explanation. Thank you for the informational video!

that pinching or necking gave me my first "OHHHHH SO THATS WHY" moment of this lesson

This is an amazing video! It never made sense to me why after max stress that the strain would increase as the stress decreased but that was a perfect explanation.

Stress keeps on increasing? But the curve shows decreasing stress?

Thank you...my "graduated" ass couldn't figure out why the graph shows decreasing stress.. it's calculating the stress on that very area where the necking happens. So area becomes less, stress becomes more. And the whole thing is based on behaviour of strain on application of stress, so there should be a steady increase of stress. WHY STRESS SUDDENLY DROPS AFTER ULTIMATE TENSILE STRENGTH.

@@TheSarcasticClown brug , its total stress by total strain bro so even though its pinching in the middle and the area is decreasing there we still calculate the stress w.r.t to the original cross section , or another way to think of it is after ultimate.. the force applied at the ends of the rod is decreasing but because its pinched cross section is also decreasing at a higher rate the net stress on that particular section is increasing.
