請各位幫幫忙

我知道某物件的 Bending Strength, 點先可以知道佢受到幾多力?
有無 formula 可提供?
有 website 都照殺 !

Thanks so much !

To: on the line 18 我現有的資料, bending strength 的 unit 是 N/m 你給我的 bending stress, unit 應是 N/m2 吧. 請問點 convert ? 點解? Thanks

Bending Stress σ ...

σ = My/I

where M is Bending Moment,
y is Height from Centroid and
I is 2nd Moment of Area
