The graph plots stress versus strain. The curve starts at the bottom left of the viewing window at the origin, goes up and to the right with a constant steepness and then goes slightly to the right. The curve then goes up and to the right with increasing steepness, reaches a maximum and then goes down and to the right with increasing steepness and ends at the top right of the viewing window. The maxima is highlighted and is labeled ultimate strength. The caption on the right reads: Based on the engineering definition of stress the ultimate strength is the largest stress that the material can withstand.
