Abstract
The objective of this experiment was to perform the tension test on a sample of a steel
and aluminum and aluminum bar in order to obtain the stress and strain curves using
the data that was obtain

Toughness
Toughness can be obtained by calculating the area under the stress strain curve
obtained from a graph in the tensile experiment and is the ability of a metal to deform and to
absorb energy in the process before fracture (matweb.)

Triangle Relations and Geometry Review
Triangle Relations:
Sum of Interior Angles always = 180
Right Triangles:
One interior angle always = 90
Hypotenuse is opposite this 90 angle, shown as C.
Other two sides are called adjacent legs, shown as A and B.
