FE mechanical exam 2024
amorphous - no clearly defined shape or form
Fouling - Accumulation of unwanted material on sold surfaces
Vector curl - Curl is a vector operator that describes a vector field's vorticity
(rotation), at a point
Vector magnitude - Vector length (hypotenuse)
Unit vector - Vector with a magnitude of 1. Sometimes called a direction vector
intensive property - Aka a bulk property. It is a physical property of a system that
does not depend on the systems size or amount of material in the system.
extensive property - a property that depends on the amount of matter in a
sample. Ex: mass and volume
Gibbs phase rule - F=c-p+2
F=intensive degrees of freedom=variance
P=# of phases

C=components
Factors=2+#of components-#phases
Density of water - 1 g/cm³ or 1000 kg/m3
1 psi to pascal - 6894.76 pascals
Hot working - when the deformation is carried out above the recrystallization
temperature.
cold working - The plastic deformation of a metal at a temperature below that at
which it recrystallizes.
Metal changes how when hot worked? - Produces a fine grained product
Removes strain hardening
Combines of annealing and cold working
Temper - Description of the amount and type of processing done to a material at
the mill, including cold work and thermal treatments
