Intoduction to Undamped Free Vibration of SDOF (2/2) - Structural Dynamics

[@pinaraksu]

I understood everything which I couldn't understand in the class with these 2 videos, 8 minutes and 6 minutes, in total 14 minutes. I wish all academicians were like you. Thank you!

[@ahmedabdulgalil6100]

9 years and you still saving more and more lives, thanks and all the best !

[@speghetti_goblin5264]

I'm always coming back to you to save my ass. Thank you for keeping these concepts so grounded, dude!

You are perfect way better than any teacher i ever had, Thanks dude

[@shazebmirza9336]

thanks man , you are doing great service to this field of engineering

[@SaurabhPonkshe1]

my professor should learn from you. THANK YOU I HAVE A PAPER TOMORROW

[@HungTran-mn2nf]

Nobody, absolutely nobody: Random guy on youtube saving my ass: Structure freeeeeeeeeeeeeeeeeeeeeeeeee !

[@structurefree]

structure fuh-reezy!

[@plainnessmanifestor7278]

Thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you

[@Civil.Structural3000]

This was awesome! I totally loved watching it. And I subscribed as well. Thank you for making this.

[@Freddy-kw2mk]

Awesome! and the graph at the end was very illustrative, thanks!

[@aymenhenikish5302]

Very nice explain, are you sure about the cycle of vibration? is there other way to plot it?

[@biting.scorpio]

Hii!! the way you explained this is awesome still I haev a question to ask i have a at 5:30 when you ask amplitude of vibration is C ...can C be greatere than X0 how can amplitude increase its intial value. In other words why is C> X0 Thanks Please help me

[@نورفارس-و7م]

I think that X0 must be =to c because it's a free vibration

[@geographicDJspeedy28]

I also asked to myself something like that. Like at the begining, when you pull the mass at X0, then the mass goes back to X negative and would return to your X0 and get bigger to achieve the amplitude. It wouldn't start going further at the begining to reach the amplitude. Right? Great video by the way :D

[@mohammedal-mashehdi1271]

thank you from the deep depth of my heart!

[@samadams8533]

This helps the concept alot so thank you, but how does the damping factor relate into everything, when you have it? And does it relate to the natural frequency at all? Also do you have any more videos on the more complex forms of SDOF systems?

[@beenay18]

shouldn't your curve be sloping downwards from initial position x(0) as the displacement decreases with time as soon as you release the stretched spring?

[@geographicDJspeedy28]

I asked myself that too, but I think it's because at his initial position xo, the mass is already pulled but he also pushes the mass at velocity vo. So that's why the mass goes up to reach its full amplitude and then go back and forth

[@25parthy]

this is a best explanation, keep rocking

[@anthonydefilippo8106]

Great walk through! Awesome refresher.

[@structurefree]

It's always nice to know that the video is helpful! Thank you.

[@hddevani]

please make complete playlist on dynamics of structure ...plz

[@andinda7915]

But shouldn't Xo be equal to the amplitude? Because if that is the intial displacement, that must be the furthest displacement, so the peak must have been Xo on ur graph

[@theodorahzombe2007]

this is absolutely amazing ..was having a hard time

[@structurefree]

Awwww, Djyeah!

[@JS-gm5wu]

Subscribed! Thanks for the introduction.

[@milkcreightronny]

Watched both of em! thanks dude!

[@mac150]

amazing as always. thank you

[@praveenkrarts]

@structurefree at x=0, velocity will be zero in the beginning but u ve taken x dot?

[@CraigBass1988]

Super video, just like your others. Should the amplitude not decrease with each period though due to energy loss?

[@structurefree]

Craig Schofield yes, if you include damping. this video i focused on free vibration without damping.

[@CraigBass1988]

Ah, ok. Thanks for replying. Keep up the great work with your videos :-)

[@speghetti_goblin5264]

he says that right at the end of the video-o-o.

[@kroos1221]

Thank you very much dude I hope you sol some proplem of this topic

[@samirtembulkar]

Was really helpful........thanks

[@talhajaved9667]

how to find the formula for maximum displacement of the graph

[@ing.erickosorio2887]

take one derivative of the function and equal to zero, solve for the the time where max happens, then back substitute that time in the function and that´s it

[@abdulrahmant8095]

Amazing thank you
