In order to use "mgh", we must find h from ground which is not a constant in every case, and y value is too little compared to h to add. Keeping the shaft as datum, we can find PE more accurately as shown in the video.
No. Rayleigh method gives more accurate results than Dunkerley because of the different equations used in finding deflections. In Reyleigh, the deflection at a specific mass location considers the deflections due to all the masses on the system. Deflections used in Dunkerly are those caused by each single mass (eg removing all other masses during calculations)
super mam thanking you whole heartedly
Very clear and simple explanation. Thank you mam.
You're welcome 🙂
Ma'am, for stodola method, if you have made any presentation please share link.
That is yet to be added. Once ready, I will share the link with you.
Ok. Thank you
Wonderful ma’am
Thank you very much
Am sharing video now
Thank you 😊
Super ma 👍👍 but why for potential energy we are not taking the formula (mgh) instead of the area under the curve...

Ma'am, is the deflection calculation(y) in this same as tht of Dunkerley?
