That's partially what I think when watching these videos.. then I realise this guy doesn't have to spend 3 hours debugging only to release you forgot to increment a counter on line 180 and forgot a semicolon on line 27. Every major has to eat a different shit sandwich
This might not answer your question but...let say you have 1 meter of wire and tension it with 100 pounds. That might be able to elastically elongate the wire by 2mm. Then take a one inch bar of steel and tension it with 100 pounds. That would move .003mm. Hardly at all. If you had a tapered bar of steel from 1inch^2 area to the thickness or cross sectional area of a wire and loaded it with 100 pounds the thicker side would hardly budge but the thinner side would move a lot. And from that example it would be safe to say that 90% of the elongation would happen in 10% of the length of the bar on the thinner tapered side.
@@holdmybipolar Ok... so isn't that the same as the total sum of cross sections? ... as governed by the taper? And in this example it says tapered ... in 3d?... is every cross section a square?
@@randyzeitman1354 I think so but it would be worded sum total of segments. With each segment having an average cross section. The force P will be applied to each segment with the change in length equal to P*Length of segment all divided by E*Average cross sectional area segment. To get a more accurate total change in length more segments are needed. Excell would be a good tool to make a bunch of segments and calculate the stretch of each segment and then sum the total. The taper for this problem is only in 2-d. The thickness t into the page is a contant. Whether the thickness makes a square at point A or B or any point in between is arbitrary to the equation. But in general the cross sectional area will always be a rectangle and can only be a square in only one location if at all depending on the values of b1 b2 and t.
Awesome man finally another engineer sepnding hours in one problem, keep it up
Thank fuck I chose compsci as my major lmao
just what i wasn’t thinking lmfaoo
that’s even more cooked 💀

@@pressure.4750no. not defintely not lol
that means your degree won't be worth much if you think it's that much easier
Your channel seems interesting, I hope so much to be an engineer someday too
Very enjoyable and informative. Thank you!
They need to make the people who made the six flags rides watch your videos
I live in Texas and they still have rollercoasters in six flags with rotting 2x4s for support beams
cool man i hop one day i can't answer cuestion like you
Isn't the stretch the integral of the dx stretch at A to B?...what's the difference what taper is?
