PhysicsMediummultiple choice

Equal-radius, equal-length wires are joined and pulled horizontally at both ends. Wire 1 has twice the modulus and half the Poisson ratio of wire 2. Choose correct statements.

Options:(select one or more)

Answer:

Solution:

$T_{1} = T_{2} = F$ .

$\frac{Δ L _{1}}{Δ L _{2}} = \frac{Y _{2}}{Y _{1}} = \frac{1}{2}$ .

$\frac{∣ Δ r ∣}{r} = \frac{ν F}{A Y}$ .

Radius-change ratio is $\frac{1}{4}$ .
