thank you sir, big help po lalo na ngayong hindi kami tinuturuan ng mga prof namin God bless

[@marielhagutin5637]

3:50 Sir ask lang po diba po kailangan mazero yung equation? sa outcome po na value ng Dv at RB magiging, -30+125.71-50-140(3.5)+94.286=0, di siya zero okay lang po ba yun? turo po kasi ng instructor namin na dapat izero

[@KennethFlores-b3m]

Thank you po sir, malinaw pa po sa mineral water

[@cebox]

You're vey welcome and thank you for the appreciaton! Hoping na makatulong kami sa study/review ninyo and also we are hoping na maishare mo ang videos/playlist and even our channel to your friends, classmates, and schoolmates. This can help us reach and help more students/reviewees/professionals like you! Thank you and God bless you po sa review! 😌😇

Ask lang po sir, saan po nakuha yung (7/2) sa pagkuha ng moment?

[@Engr.Snow.]

Cinonvert yung uniform loading into concentrated load then yung load na yun sa gitna napunta and gitna ng 7 meters is 3.5 meters which is also = 7/2

[@lunarity1564]

​@@Engr.Snow. constant po ba na nasa gitna yun?

[@animated_drew]

Sir, pwede po mag-ask? Paano po naging positive ang clockwise moment? diba po hogging effect siya. Medyo na-confuse po kasi ako sa tinuro ng prof namin and based din sa nasearch ko sa internet. Sana po masagot. Thank you.

Sir, yong pagkuha ng Reaction at B is minoment ko siya at point D. So summation of Moments at D is -30(8) + Rb (7) - 50 (3) - 20 (3.5) =0 tama po ba sir?

Master, ask ko lang, pano po ba pag sa actual beam is continuous nakapatong sa columns (4 columns) actually pergola sya sir. Pano po ba malalaman kung fixed or simply supported s'ya? Overhanging both ends po sya na may internal supports, pano po consideration ng analysis nun sir?

[@cebox]

Depende sa drawing. Pero since sabi mo po na nakapatong, roller support lang po yan. (Sorry for the very late reply.)

[@genielilao381]

Ah so pwede dun sir ang three moment equations, na positive moment between supports ang magiging result tad negative moment at supports po? Tama po ba sir?

[@JaayyYT]

Hello po sir, ask lang po kung paano nyo na kuha yung Dv = 94.286 KN?

[@al-krimaralias9356]

Sir, pwede ba mag review for board gamit ang tutorial ninyo? Like dito sa shear n moment for beams at iba pang tutorial?

[@cebox]

All concepts naman po engr na tinuturo sa undergraduate noon ay siya ring concept na tinuturo sa board exam review, it just happened na since graduate na kayo, at nagrereview na lang, from the word itself review, alam niyo na ang basic concept, kaya ang review is mabilisan na akala ng marami ay parang shortcut sa board exam review. Of course, there are instances na may mga shortcut talaga, pero maiintindihan mo lang yung shortcut na yun kung naiintindihan mo ang basic concept from undergraduate. Overall, all concepts here will totally be used for your review, engr. 😊😇

Distributed load means nakadistribute siya sa specific length. Hanggang 7m lang ang distribution nung rectangular load.

hello po sir, bakit po hindi included yung uniformly distributed load po na from B to D sa shear at B?

[@glennrazon4388]

paano po nakuha yung answer sa DV? iba po kasi lumalabas sa calculator po. salamat po sa sasasagot

[@roseeminem6918]

Ginagawa kasi na shift solve na sa calcu yan kaya makukuha na yung Dv. Pero kung imamano mano. Isolve mo muna yung 50(4)+20(7)(7/2)-30(1). After that, ililipat mo yung -Dv(7). Kaya magiging outcome is.. 50(4)+20(7)(7/2)-30(1)=Dv(7) After solving yung sa left side, idi-divide mo siya sa distance ng Dv which is 7. Lalabas na ang sagot dun
