Question

The shear modulus of an elastic body under shear deformation is plotted against the reciprocal of the largest displacement. The slope has units of
Options
A kg·m/s
B kg/s²
Correct Answer
C kg·m/s²
D kg·m²/s²
Correct Answer

Option B is the correct answer.

Detailed Explanation

Shear modulus has units of N/m². Reciprocal displacement has units 1/m. Slope = (N/m²)/(1/m) = N/m = kg/s².

Hint

Divide the units carefully using dimensional analysis.
