Zoned Surveys - ✔✔Type of survey that allows computations to be performed as if on a
plane will accommodating larger areas.
State Plane Coordinate System - ✔✔Rectangular systems that use a partial
latitude/longitude system for baseline references
Benchmark - ✔✔The common name given to permanent monuments of known vertical
positions
Control Stations (or Triangular Stations) - ✔✔Monuments with known horizontal
positions.
Leveling - ✔✔The act of using an engineer's level (or other leveling instrument) and rod
to measure a vertical distance (elevation) from an arbitrary level surface.
Differential Leveling - ✔✔The consecutive application of direct leveling to the
measurement of large differences in elevation
Azimuth - ✔✔Given as a clockwise angle from the reference direction, either from the
north or from the south. May not exceed 360 deg.

,Deflection Angle - ✔✔The angle between a line and the prolongation of a preceding line
is a deflection angle.
Bearing - ✔✔Referenced to the quadrant in which the line falls and the angle that the
line makes with the meridian in that quadrant. May not exceed 90 deg.
Traverse - ✔✔A series of straight lines whose lengths and directions are known.
Open Traverse - ✔✔A traverse that does not come back to its starting point.
Closed Traverse - ✔✔A traverse that comes back to its starting point.
Geometric Requirements of Closed Traverse - ✔✔Sum of deflection angles is 360 deg
and sum of the interior angles (of a polygon) with n sides is (n-2)*(180 deg)
Traverse Closure - ✔✔The line that will exactly close the traverse.
Dynamics - ✔✔The study of moving objects; concerned with bodies that have
accelerated motion
Kinematics - ✔✔The study of a body's motion independent of the forces on the body; a
study of the geometry of motion
Particle - ✔✔A body in motion where rotation of the body is absent or insignificant; has
no rotational kinetic energy
Rigid Body - ✔✔Type of body that does not deform when loaded and can be considered
a combination of two or more particles that remain at a fixed, finite distance from each
other.
Kinetics - ✔✔A study of the forces that cause the motion
Rectilinear Kinematics - ✔✔Type of kinematics that refers to straight-line motion.

, Curvilinear Motion - ✔✔Type of motion that occurs when a particle moves along a
curved path.
Potential Energy - ✔✔Stored energy; when energy comes from the position of the
particle.
Absolute Pressure - ✔✔Pressures measured with respect to a true zero pressure
reference.
Gage Pressure - ✔✔Pressures measured with respect to atmospheric pressure
Surface Tension - ✔✔The tensile force between two points a unit distance apart on the
surface, or as the amount of work required to form a new unit of surface area in an
apparatus.
Stress - ✔✔Intensity of Force Per Unit Area.
Hooke's Law - ✔✔A simple mathematical statement of the relationship between elastic
stress and strain; stress is proportional to strain.
Normal stresses - ✔✔What type of stresses are normal strains accompanied by?
Shear stresses - ✔✔Why type of stresses are shear strains accompanied by?
Normal Strain - ✔✔A change of length per unit of length
Shear Strain - ✔✔An angular deformation resulting from shear stress
Vertical Depth and Density - ✔✔In fluids, what is pressure a function of?
Isotropic Material - ✔✔A type of material that has the same properties in all directions
(i.e. steel)
Anisotropic Material - ✔✔A type of material with properties that vary with the
direction of loading.
