Question 26 / 40:  Which relationship below correctly defines Young's modulus for one-dimensional deformation?
A  It is the ratio of stress to strain.
B  It is the ratio of strain to stress.
C  It is the ratio of dimensionless strain to stress.
D  It is the ratio of force to area.
E  It is the ratio of stress to elongation.
