trying yo figure this out:
the graph of stress concentration factor K for flat bars with a circular hole geometries are shown in the diagram link below. a load of 50kN is applied to the plate. the width of the plate b=100mm with a thickness of t=10mm
find the maximum stress for the following:
1. plate without hole
2. plate with hole (diameter 50mm)
3. how much is SCF? well k=nominal stress / maximum stress but I am not sure how to get the maximum stress, is it s chart or the graph below?

this is what i have done so:
stress=P/A
p=50X10^3
A=(b-d)h = 50mm x 10mm = 500mmsquared = 0.0005m squared??
so nominal stress is = 50x10^3/0.0005 = 6000?
