Answer:
μ = 0.436
Explanation:
Given:
Change in diameter, ΔD = 7 × 10⁻³ mm
Original diameter, D = 11.2 mm = 11.2 × 10⁻³ m
Applied force, P = 14100 N
Cross-section area of the specimen, A = =
Now,
elongation due to tensile force is given as:
or
on substituting the values, we get
or
where,
is the strain in the direction of force
Now,
now, the poisson ratio, μ is given as:
on substituting the values we get,
