Sir! we would very much appreciate a lecture series on another mind boggling subject of mechanical engineering called 'machine design'. When it comes to subjects related to 'mechanics', there is none better than you. From Pakistan
You made me wonder... wouldn't the string ONLY be straight as long as the string was perfectly aligned with the y-axis? Any variation would lead to an x component which would make the string's tension head to infinity, wouldn't it? Also, I really enjoy your lectures (it's very hard to pause a human being in real time, so you can understand a concept!)
This is a great example of an application of these concepts but it would be good to note that for engineering purposes, or more specifically, construction purposes, a thin string will be straight enough - who cares if it's off by a couple tenths of a millimeter over, say, a 10m wall? And if higher precision is desired, one can add intermediate posts to retain the relative straightness. Of course for parts that require precise machining where tenths and hundredths of a millimeter matter you would need something else, and for that we have lasers.
omg this is a cool proof i like it though i would say that depending on the situation and the length of the wire you can say that it's straight if the angle is small enough
When youre done with your statics, dynamics, ans solids, could you junior level mechanical design analysis i think some school call it machine analysis. Im going into that class next semester and would love some extra help. Thank dr
I love a teacher who can make you actually laugh

DR. Hanson ,thank you for another outstanding lecture in Statics.
Is there any other
Mind blown. Well said
Dr.Hanson you are teaching very good and you are an energetic person.
I enjoy watching your video's for statistics.
God Bless you! Including real life example and interesting facts makes the subject so much more interesting!!! Thank you so much sir, have a great day
Such a interesting lecture !! Love the way you teach!!
Thank you. That is awesome. I never thought about it, but it makes perfect sense.
thank you Jeff!
Thanks for blowing my mind! 🤯🤯

Yup, any force that is not colinear with the string will cause it to deviate.

"Ain't No Such Thing as a Straight String" ANSTAAST
This thing like endurance limit for shaft but I think is properly depend on material propriety also
cool content bro
this video was so good. also happy pride month to the string
Great lectures. Thank you.
welldone professor, what makes you say that the tension in the string are the same
so cool
Can we say stiff members are strings with infinite strength on that orientation? Since deflection is low in those?
great content, very interesting!!

Straight string until you learn about the Corrioli's effect on a later chapter. Amazing exposition.

The catenary curve! Hyperbolic cosine never looked so good.
What was that? Blown away!
very helpful
Nice vid man!!!!
Mad Cool!!
This thought experiment was almost like a calculus problem.
I thought we were supposed to consider the force of gravity pulling on the light.
That is what the 100lb force pulling down is
wow, very interesting
your symbol for pound takes longer to write than "lb"
But it's less likely to be confused for 16
nice
That must be some strong cable 💀
Today I learned I'm a string
🤯🤯🤯😂😂😂
that string me fr
asymptotes. fun lecture, thank you.
