Here's a taster:

Young's Modulus
If you plot stress against
strain for an object
showing (linear) elastic
behaviour, you get a
straight line. This is
Stress
because stress is directly
proportional to strain.
The gradient of the
Strain straight line graph is the
Young's Modulus, E.…read more

Here's a taster:

Stress
Youngs modulus = E=
Strain
E is a constant and does not change for a given
material. It in fact represents the stiffness property of
the material. Values for the young modulus of
different materials are often listed in the form of a
table in reference books so scientists and engineers
can look them up whenever.…read more
