ultimate TENSILE STRESS
just doing a question paper and experiencing *quite a few* minor difficulties.
1) Ultimate tensile stress- on a graph would that be exactly the point where the straigth line becomes a bit bent ...or...the curved bit where the graph begins to slope downwards..?
....thankyou in advance =D

Ultimate tensile stress just the maximum of the graph - i.e. the highest point on the graph, the maximum stress it can possibly take.
Tensile strength is the point where it breaks (I'm not really sure how these things are defined)? If so it will be the stress as the point where the curve ends

the point where the graph is no longer a straight line is called the limit of proportionality.
The elastic limit is usually a bit further on. The yield stress is the stress which causes plastic deformation, i.e. at the elastic limit.
The ultimate tensile strength or fracture stress is that which makes it break.
