Passage / Comprehension

The rectangular elastic material in the diagram is compressed separately by $1 mm$ parallel to (i) x, (ii) y and (iii) z.

The force constant k is

Answer:

Solution:

Assuming isotropy, $Y$ is direction-independent.

Lengths along $x, y, z$ are $3, 5, 1 cm$ .

$k = \frac{YV}{L ^{2}}$ is largest along z.

For fixed compression, $σ = \frac{Y Δ L}{L}$ is largest along z.
