Question

The shear modulus of an elastic body under shear deformation plotted against the reciprocal of the largest displacement has a slope with units of:
Options
A kg m/s
B kg/s
C kg m/s²
Correct Answer
D kg m
Correct Answer

Option C is the correct answer.

Detailed Explanation

Shear modulus G = stress / strain. Stress = F/A (N/m² = kg·m⁻¹·s⁻²). Reciprocal of displacement introduces factor m⁻¹. So units: kg·m/s².

Hint

Check units of stress and strain.
