PLTW POE Finals With Complete Solutions
Statics - Answer The study of objects at rest
Newton's 3rd Law - Answer For every action force, there is an equal and opposite
reaction force
Vector Quantities - Answer Physical quantity that has both magnitude and direction
Force - Answer Pushing of pulling interaction of objects
Centroid - Answer Object's center of gravity or center of mass
What does a moment equal? - Answer Force x Distance
Static Determinacy - Answer A static determinate structure is a structure that can
mathematically be solved
Element - Answer Consisting of only one type of atom
Metalloid - Answer of or being a nonmetallic element that has some of the properties of
metal
Manufacturing Process - Answer A series of operations that transform raw or unfinished
materials into finished products
Cell Shop Answer Manufacturing linked to final assembly; lean production system; one
piece flow system
, Project Shop Answer Product being manufactured cannot be easily moved during
production; production processes are brought to the product
Lean Manufacturing Answer 100% good units flow from process to process
Integrated Quality Control (IQC) Answer All employees are also inspectors
Forming and Metalworking Answer Molding shape, size, and physical properties of a
material
Rolling - Material passes through series of rollers which reduces thickness
Forging - Shaping metal by heating and hammering
Elastic Limit -Maximum stress a material will withstand without permanent deformation.
Resilience - Physical property of a material that can return to its original shape or
position after deformation that does not exceed its elastic limit
Yield Point -Point at which deformation becomes permanent
Plastic Deformation - Answer Unrecoverable elongation beyond elastic limit
Toughness - Answer Shows both strength and ductillity; total area under stress-strain
curve from test initiation to fracture
Probability - Answer a measure of how likely it is that some event will occur
