Mechanical Vibration: Spring Element

[@dennispatel4789]

Hey Azma,
I just wanted to thank you and let you know, your videos are VERY helpful. i was so lost about the topic till i saw your videos, i am doing my HW right now and you have no idea, how grateful i am. Thank you once again and please keep these videos coming.

Hello
I am from suadi arabia
Thank you very much from hurt😍
You should getting like !!

[@jspadmanabhan8451]

Good and very nicely explained

[@mosesarchibong4619]

sir, please come to Nigeria, l love your work

[@chinedunwasolu4913]

and do there?

[@randallsawyer365]

I think you did the equivalent stiffness wrong for the cantilever beam and spring at 12:28. I though you only directly add if it is in parallel

[@touseef_akhtar]

I also thinks the same

[@AzmaPutra-channel]

It is parallel. You can try by calculating the potential energy for each beam and the spring. The total stiffness will be ended up with kb+ks.

How do u Decide as to whether to considering summing of P.E or K.E or forces of each element of the system for finding the Keq or Mass eq. ??

[@AzmaPutra-channel]

K. E. is for rigid body having mass. P. E. is for elastic element which is springs, rubber, etc.

[@izwanahmad475]

What is the unit for theta in the last case? Radian?

[@AzmaPutra-channel]

Yes. It should be in radian.

nice video thnx
plz can u tell what program are u using to teach?!

[@AzmaPutra-channel]

Hi Mark. Thanks. I used 'Explain Everything' app in my iPad:)
