Answer:

Step-by-step explanation:
Modulus of resilience is the maximum amount of strain that an elastic material can support per unit volume, without deformation, and is calculated using the following equation:
μ = σ^2 ÷ 2*E
σ = yield strain= force / cross area
force = 500N; area=π*
=

σ =

E= young modulus: relation between stress and strain, measures stiffness
E=σ/∈, where
∈=(L-Lo)/Lo=7*

where
L=current length = 10 cm * 1.007 = 1.0070*
m
Lo=original lenght = 10 cm = 1.0*
m
so, E=σ/∈ =

μ = modulus of resilience =
