Talk:A-level Physics (Advancing Physics)/Stress, Strain & Young's Modulus

I think the toughness, the area under the curve should say the x-axis instead of y-axis

question
a wire is cut into two equal parts, its ability to withstand with weight will be a) increased      b) decreased        c) remain unchanged       d) I don't know

Young's Modulus
I think it would be helpful to include an explanation in the paragraph about Young's Modulus to why "values for stress and strain must be taken at as low a stress level as possible"
