hope this helps.

dont forget that strain has no dimension or unit.

Answer 2

Explanation:

✳Answer✳

$shear \: strain \: - \: \frac{ro}{l}$

$r \: - \: radius$

$o \: - angle$

$l \: - length$

$(1cm \: - \: \frac{1}{100} m)$

$shear \: strain \: - \: \frac{1 \times 0.8}{100 \times 2}$

$\frac{0.4}{100}$

$0.004$
