FE Engineering Exam with correct
ansewrs
conservative vector field - correct ansewrs∇ X F= 0
linear differential equation - correct ansewrsThe dependent variable and its derivatives appear in
additive combinations of their first powers
homogeneous equation - correct ansewrsWhen the right side of the dif eq is 0
constant coefficient equation - correct ansewrsGiven a⋅y``(x) + b⋅y`(x) + c = 0, the characteristic
equation is:
a⋅r² + b⋅r + c = 0
good electrical conductivity - correct ansewrsthe conduction band is half full
isolated system - correct ansewrsdoes NOT allow the transfer of either mass or energy
system interacting - correct ansewrsforce is introduced form one to another
sublimation - correct ansewrssolid to gas
deposition - correct ansewrsthe change of state from a gas directly to a solid
Oxidation - correct ansewrsThe loss of electrons from a substance involved in a redox reaction.
(An anode reaction)
key to reinforce a material - correct ansewrssimilar thermal expansion
creep failure - correct ansewrssteady load at elevated temperatures
metal fatigue - correct ansewrsa weakening of metal due to stress, resulting in an accumulation
of small cracks even below the yield stress
upper and lower yield points - correct ansewrsthe barrier material to dislocation motion posed by
impurity or solute atom. In mild steel, carbon produce such a barrier.
off-set yield stress - correct ansewrsthe stress corresponding to a specified plastic strain, usually
0.2%
ductile fracture - correct ansewrsa cup and cone fracture surface
