Answer:
diameter = 45.251 inches
Step-by-step explanation:
initial length = 1.3
initial diameter = 45.27
tensile stress = σ = 1140
modulus E = 904672
v = 0.33
we calculate longitudinal strain = σ/E
= 1140/904672
= 0.0012601252
general relation for
v = -Ed/El

we cross multiply
-Ed = 0.33 x 0.0012601252
= -0.00041584132in

when we cross multiply,
df - 45.27 = -0.00041584132*45.27
df - 45.27 = -0.018825136
df = -0.018825136 + 45.27
df = 45.251 inches
