100% Verified Exam Prep and Comprehensive
Rationales
Included
, Strain The response of a material due to stress, defined as the change in length divided by
the original length
Stress A force on a material divided by the cross sectional area of the material
Stiffness The resistance of and elastic body to deflection by an applied force
Super alloy Alloy the exhibits exceptional mechanical properties, resistance to thermal creep
deformation, good surface stability, and resistance to errosion
Synthetic fibers Fibers made from man made materials, spun into threats; the joining of monomers
into polymers through polymerization
Tempering Heat treating process that increases the toughness of iron based metals by heating
the metal and allowing it to cool in air. This can increase ductility and decrease
brittleness
Knots Imperfections in timber, caused by the growth of branches in the tree that reduces
its strength
Lacemaking A method for creating a decorative fabric that is woven into symmetrical patterns
and figures
Laminated boards Sheets of material made from layers of veneers (plywood)
Laminated object manufacture (LOM) A rapid prototyping system that creates a 3D product by converting it into slices,
cutting the slices, and joining the slices
Lamination Covering the surface of a material with a thin sheet of another material typically for
protection, preservation, or aesthetic reasons
Load Capacity (Robots) The weight a robot can manipulate
