just a project i have to start working on soon wanted to know if i can get any useful information about it please thanks

haha that's ok...ive managed to get the maximum stress as 110MPa since 2.2x50MPa = 110 000 000 thats part 2 done but what about part 3 the SCF?

i've got d/b to be 0.5 since d=50 and b=100 d/b=50/100 = 0.5 using the graph i get 2.2?

how do i do that?

cant do the second bit though cant find the correct area either

ive found the stress for the plate without the hole to be: P/A = P/bt= 50000/0.001 = 50MPa

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...

using the isothermal transformation diagram provided of an iron-carbon alloy at eutectoid composition, determine the final microconstituants and approximate percentages of a small specimen that has been subjected to the following time-temperature heat treatments. in each case assue the specimen...

yeah I am sort of new to this so its taking a while. thanks

well...i've decided to plot stress against the logarithm of the N-values? could you please show me how I am supposed to deal with the figures 3 and 3.7?

yeah

whats is the difference between crystalline and non-crystalline ceramics?

I'm using this diagram: see attachment

what is eutectoid composition for an iron-carbon alloy? what would happen to the iron-carbon alloy while cooled from the alpha phase to room temperature at this composition?

why would you recommend a log-log plot? can i not just plot it as stress against logarithmic scale of the cycles to failure?
