Using Simpson's Rules to calculate the geometric center (COF) of an enclosed space

This video continues with the teaching of Simpson's Rules and focuses on the procedure for calculating the centroid or geometric center (COF) of an enclosed space.

Man your an amazing teacher thank you from a highschool dropout realising what he missed out on early in life thank you so much

[@raymondallenjhangiani7670]

Very well explained 🙏 thank you sir !

[@mukeshpunetha9458]

Thank you sir for your precious knowledge

[@Pecannasty]

What's the benefit of taking your lever from aft instead of center? Is it due to having an even amount of ordinates?

[@SteeringMariners]

You get a positive lever for any point (from aft to fwd). Otherwise you can take any point for reference.

[@apurvshrivastva4184]

Sir u just teach wonderful 😊😊

[@mikestubbs1708]

...good problem here...well presented and worthwhile doing...!!

[@SteeringMariners]

Thanks Mike:)

[@niladripaul7834]

Sir please show a problem when an ordinate is inserted in between or the interval changes between ordinates.

[@Yogeshkumar-kg4eg]

The half ordinates of a ship waterplane area 210 m in length at equal intervals, commencing from after end are 2.0,3.5,5.8,7.5,9.0,6.0,3.0,0.0m. Calculate her tpc and LCF.

[@Yogeshkumar-kg4eg]

I have calculated the TPC. But for LCF. When I am using your formulae error of 2 m is coming. Please assist 🙏

[@pappumurali8758]

Its rule no.2 sir, in first sum, thank you

[@richardvillier536]

Yes rule no.2

[@krishnachowdhry5936]

here sop for g2 the ordinates are multiplied from top so the g2 7.8 is from top or bottom?

[@SteeringMariners]

jitendra chowdhary from bottom 😊

[@yellowpotato5588]

Sir, why did we take the levers downward but not upward?

[@krishnachowdhry5936]

i think in ques gc is asked only for bulkhead not for the shape

[@moganmurugan1441]

hi how do you find LCB using simpsons rule with volume? thank you

[@darylberro7357]

Is it really necessary to use the aft as the base for calculating where to start from 0h to 6h... so on?

[@SteeringMariners]

Yes:)

[@fazalfanaskar1133]

Hi sir, can u please explain some question containing appendages

[@shubhambera6857]

As there are 10 ordinates, you said you are using Simpsons 1st rule but aren't you Using Simpsons 2nd rule? 1332332....?
Kindly please clarify.

[@apurvshrivastva4184]

Let it be... Just take it as a mistake and move on... Assume like sir had used 2nd rule

[@mfaisal2873]

Watch 10:40 minutes on this video, Sir already did clarify.Thank you.

[@sailortanwar7582]

Sir plz make a short video for lcg lcf tcg calculation.

[@arjansulhan3047]

thank you sir

[@pablagurmeetsingh4380]

Who to calculate KB?

[@krishnachowdhry5936]

y u hv taken 7.827 in last line

[@SteeringMariners]

jitendra chowdhary the value was 7.827 but I wrote 7.8 initially. You can take 7.8 and you will get the same answer.

[@RAVICHOUDHARY-vg4op]

I think sir it was rule number 2

[@apurvshrivastva4184]

Visit our college sir... If possible...
