Expert Solution
the relevant state of the medium around a point must be
represented by two second-order tensors, the strain tensor
(in lieu of the displacement 
) and the stress tensor 
(replacing the restoring force 
).The analogous of Hooke's spring law for
continuous media is then
where 
is a fourth-order tensor (that is, a linear
map between second-order tensors) usually called the stiffness
tensor or elasticity tensor. One may also write it as
Hooke's law only holds for some materials under certain loading conditions. Steel exhibits linear-elastic behavior in most engineering applications; Hooke's law is valid for it throughout its elastic range

Learning Goal:
To understand the use of Hooke's law for a spring.
Hooke's law states that the restoring force
F⃗ on a spring when it has been stretched or
compressed is proportional to the displacement
x⃗ of the spring from its equilibrium position.
The equilibrium position is the position at which the spring is
neither stretched nor compressed.
Recall that F⃗ ∝x⃗ means that
F⃗ is equal to a constant times x⃗ .
For a spring, the proportionality constant is called the spring
constant...

In some materials the relationship between stress and strain
during plastic deformation is given by σ
= σy+ K(ε − εy) n where
K and n are constants. What is the energy absorbed by the
specimen during plastic deformation in a tensile test if the
material yields at a strain of εy and fails at a strain
of εf?

Hooke's Law
Objective: To verify Hooke’s law that the extension of a spring
is proportional to the stretching force applied once the elastic
limit is not exceeded.
a) Mention at least three important precautions that you take
while performing the experiment? b)Give one example where Hooke’s
law can be applied. c) Draw the forces experienced by the mass
spring system. d) Name the forces and state the law applicable
here. e) If a mass of 250 grams is suspended, then find...
