- - - 1 94 S01 so this is a simple→ (1.9) pin→ that it can be made from
- - - 1 95 S01 uh steel→ or concrete→ or wool↘ so regardless of the material↗
- - - 1 96 S01 we expose→ (.)equal→ (4.4) so if we expose equal forces→ (.)
- - - 1 97 S01 and then this is the ⁎length of the ⁇beam⁇→ for example f⁎↘
- - - 1 98 S01 so we- uh- we- uh→ there are two equal forces at the two ends↘
- - - 1 99 S01 and they are equals↘ and they are normal to ∇the∇ cross
- - - 1 100 S01 section of the beam↘ and it's a xxx the section↘
- - - 1 101 UNK (.)
- - - 1 102 S01 so the ↑stress→ which is represented with a (.) signal→
- - - 1 103 S01 and because it's a tensile stress→ we call it ⁇sigma⁇ t↘ it's
- - - 1 104 S01 equal to acting force divided by ⁎cross sectional area⁎↘
- - - 1 105 S01 so what is the cross ⁇section⁇ area↗ ⁎if we→ um:⁎↘
- - - 1 106 S01 °don't have another color°↘ but if you (.) ⁎uh⁎ (1.9)
- - - 1 107 S01 do a section here↘ create a section A↘ (.) A↘ and see the:
- - - 1 108 S01 inside the member as a xxx→ (.) so→ ∆because it's a-∆
- - - 1 109 S01 because xxx is a→ (.) ⁎it's gotta be any sh- ⁇shade⁇⁎↘
- - - 1 110 S01 ⁎but for example it's a concrete beam⁎↘ so you have the
- - - 1 111 S01 height→ (.) and the base↘
- - - 1 112 UNK (.)
- - - 1 113 S01 so the area is→ A xxx by B↘
