The outro music was an original work of Ting-ting Calzo-Fournier and Jungee Marcelo which was used as a theme song of the 90's kids program of ABS-CBNS "Mathtinik". The outro line was also adapted from the lyrics of the song "maglakbay, mag-enjoy, maglaro, manaliksik, maging Mathinik". The outro music is not ours but belongs to their respective owners.

Hello, yong reaction po sa RB hindi siya 38.5? di po ba maging 36.5-10(6)-1/2(10)(3)+RB=0 may 1/2 kasi triangle or wala na?

[@rosalestomlesther1772]

sir sa cut nyo po why po naka negative shear? salamat po sa mga video

[@josepinotubiano9794]

same huhu

[@ilikexu9946]

Hindi po ba talaga mado-drawing yung moment diagram gamit ang area method kapag may trapezoidal load?

[@garonmargaretmae7238]

same thoughts. sabi ng prof namin pwede raw iextend yung triangular load pero di naman sinabi samin paano haha

[@ralphalexanderpulido3268]

@@garonmargaretmae7238 yes pwede syang i-extend tas mag ratio and proportion para makuha kung gaano kahaba yung length of extension

[@elaine7271]

hello! thank you po sa vid na to!

[@JABEETV]

Hi! Do you mean area under the curve sa shear diagram? Yes pwede po siya gamitin kapag hindi po nagcross yung curve doon sa X-axis ng shear diagram. Once na nagcross kasi, first you need to find the location of the PZS, and then from that using that formula pwede mo makuha yung area sa taas or yung positive area. Pero getting the area below is not possible already using that formula. ayun po, hope that helps! :)

[@JABEETV]

joke ahha gets ko na pala tanong! HINDI po pwde yung formulas na (1/n+1)(bh) kapag yung curve ay naggaling sa Trapezoidal Load. Applicable lng po yan kapag yung curve mo ay galing sa Triangular Load. That formula po kasi ay ginagamit pag along the curve ay meron ka nung apex or the maximum point which has a slope of zero. In the case of triangular, one point in the curve will be zero kaya pwede po siya. However pag trapezoidal, eh wala po. Kaya hindi siya pwede. Ayun haha sana nakatulong. ang gulo ko rin eh ahaha thank uu!!

[@elaine7271]

hello! hahahah gets po! basta any diagram na manggagaling sa trapezoidal load, matic na hindi na applicable yung formula. for deflection ko po kasi sana gagamitin yung area ng moment diagram, buti po ay nagshed ka ng light chz HAHAHA anyway, thank you again!!
