After reading my first question I feel slightly embarrassed as to what I asked and understand completely why, what I said was incorrect, After looking at what I had calculated I had actually found my answer but didn't realise until I went through my results a third time
The stress would be arising from the change in temperature across the piece of material,
So firstly I would need to find out if there is a temperature difference between the heated side of the material and the non heated side of the material?
If there was no temperature difference and the...
secondly if this is true would it also be correct in staying as long as this average was below the objects breaking stress it would not fail even though the total stress may give a number larger than the breaking stress for the material?
I'm currently working on a problem which involves looking at the stress involved on the material during the heating phase,
the Scenario is If I have two heaters, one heater producing a greater output than the other (i.e heater 1 = 50watts, heater 2 = 100 watts), although they both provide the...
