Tensile stress

有冇CHING可以教下我
PART A係唔係咁做
PART B唔係好明佢講咩,咩叫applied in a widthwise direction,姐係指緊邊個方向

I believe your first line of calculation..... The "w" refers to the dimension perpendicular to the direction of the applied stress. However, the rest of your cal appears to be wrong.

From your calcuation, it seems to show bigger the hole relative to the plate -> smaller tensile stress. It is not reasonable....Pls have a look in the bottom of this webpage: [url]http://www.fracturemechanics.org/fm/hole.html[/url]
