    Good eve sir, bakit po pababa ung deformation kung mataas naman po yung vertical force nc AC which is 3111 ?

    • @cebox

      Take note, that 3111.48 lb is inclined, not vertical force. Yung 2000 lb is vertical force.

      That force of AC is the internal force to resist 2000 lb, not necessarily that force will pull the 2000 lb pataas. Hindi ganun po nagwowork yun. Imagine, ikaw po yung 2000 lb, then may cable, does that cable will brought you upward? No, right? Then what will be the displacement? Downward due to your weight 2000 lb at that point.

    ano po reason bakit need mag elongate nung cable ac na original?

      Mechanics of "Deformable" Bodies na po tayo, wala na po tayo sa "Rigid" Bodies. Kaya ang mga materials po rito is inaaral natin ang kanilang strength in terms of their deformations kaya madedeform po talaga mga materials sa mga discussion natin. Elongation is deformation.

    Sir pano pag hindi given yong E or strain?

    • @cebox
      @cebox  2 ปีที่แล้ว

      Constant po kasi ang E sa different type of materials. Usually, binibigay iyon kasi hindi naman pwedeng memorize ng bata lahat ng E. Sa Steel, 200 GPa. And sa strain naman, that is equivalent to E/σ.

    sir paano po kapag malaki ang deformation? mag-aassume pa rin ba na perpendicular yung angle sa point C?

    • @cebox
      @cebox  3 ปีที่แล้ว +10

      Hi. Ahm kapag deformation po, maliit lang po talaga yun. As you can see, 0.00 something lang ang mga deformation, kasi dapat talaga maliit lang yun at hindi pwedeng lumaki, kapag lumaki yun, wala na, wasak na ang structure, so I think you don't need to worry about malaking deformaton kasi hindi yun pinapahintulutan sa code, so we can assume it perpendicular. :)

    sir, bakit po yung modulus of elasticity po yung kinuha sa deformation ng AC?

    • @cebox
      @cebox  3 ปีที่แล้ว

      Hi. Hindi ko po gets tanong ninyo? Kasi hindi naman po natin kinuha yung Modulus of Elasticity e? Yung deformation delta ang kinuha natin...

    • @cebox
      @cebox  3 ปีที่แล้ว

      Ah yes. Hindi ba tama? Modulus of elasticity ng Cable AC, ang cable yun yung steel cable AC. So modulus ng elasticity ng steel gagamitin.

      Hmmm baka 8ft lang ang cinonvert mo? If cinonvert mo ang 8 ft into inches, dapat puro inches din yung ibang variables and constant.

      Hmmm kasi may loading tayo at point C na downward, kaya hihilahin lang ng force yung C pababa...
