D. Selective Laser Sintering
E. None of the above
F. Vacuum Molding
A material comprised of two or more
materials working together, where each
constituent material retains its unique
identity, contributes its own structural
properties, yet upon combination the re-
sulting material has superior properties
to those of its constituents:
A. Thermoplastic
A. Thermoplastic
B. Thermoset
C. Elastomer
D. Composite
E. Alloy
F. None of the above
In forging operations, when material
does not move relative to the platen sur- Sticking friction
faces it is known as _____. In this case
, MCHE 365 - Test 4
we can assume that the frictional stress
equals the yield strength in shear.
