PLTW POE Finals - Energy and Manufacturing

Energy in motion

What is the pushing or pulling interaction of objects?

V=IR R=V/I I=V/R

For every action force, there is an equal and opposite reaction force?

Allows current to flow in only one direction

What is a thing consisting of only one type of atom?

Use of gas flowing under pressure to transmit power

Activity with observable results

A measure of thermal transmittance through a material

Product being manufactured cannot be easily moved during production, Processes to Product

Use of liquid flowing under pressure to transmit power

Molding shape, size, and physical properties of a material

Result of an experiment

Current that flows from the negative side to the positive side (science disciplines)

Unrecoverable elongation beyond elastic limit

Movement of electrons

All employees are also inspectors

Measures properties in electrical circuit

of or being a nonmetallic element that has some of the properties of metal

materials that allow electric charges to flow through them easily contain 1-3 valence electrons

Current that flows from the positive side to the negative side (engineering disciplines)

Maximum stress that a material will withstand without permanent deformation.

a measure of how likely it is that some event will occur

Manufacturing connected to final assembly; lean production system; one piece flow system

the ratio of the number of favorable outcomes to the number of possible outcomes

shaping metal by heating and hammering.

Atmospheric pressure + gauge pressure

Set of all possible outcomes

materials that do not allow electric charges to flow through them easily; 

A series of operations that transform raw or unfinished materials into finished products

A quantity representing the amount of energy in a system that's not available for doing work

What does a moment equal?

Gases are affected by:

Subset of sample space

A moving object

Controls direction and amount of flow

Tubes or hoses

the collection, evaluation, and interpretation of data

Electrical component that resists flow of electrical current

Shows both strength and ductillity; area under stress-strain curve from initiation to fracture

Converts mechanical power to fluid power

the physical property of a material; can return to its original shape or position

100% good units flow from process to process

point at which deformation becomes permanent

Ability to work

Material passes through series of rollers which reduces thickness

Converts fluid power to mechanical power

What is the study of objects at rest?

The velocity of a moving body at the starting

resistance to the flow of heat; AKA r-value

What is a physical quantity that has both magnitude and direction?

Stores fluid

What is the object's center of gravity or center of mass?

probability based on the repeated trials of an experiment

A static determinate structure is a structure that can mathematically be solved?
