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.

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.)

Pacing Lab Report
Introduction: The objective of the pacing lab was to determine the length of each

distance of a field. This method is useful when a person wants to draw
Procedure:
1) Set up total station at first traverse point (benchmark).
2) One member had to hold one prism pole on the last point in the traverse and the other on
traverse No.2 and then back sight the setup to the last point.
