A-LevelPhysicsDeformation of solidsMay/June 2010Paper 1 Q211 Mark
In stress-strain experiments on metal wires, the stress axis is often marked in units of 10⁸ Pa and the strain axis is marked as a percentage. This is shown for a particular wire in the diagram. [Figure 21.1] What is the value of the Young modulus for the material of the wire?
A6.0 x 10⁷ Pa
B7.5 x 10⁸ Pa
C1.5 x 10⁹ Pa
D6.0 x 10⁹ Pa
