Quizs on Glossary Terms 1

Additive manufacturing

• Creation of complex components using 3D computer models; material is added in a series of thin layers to build up the required shape.

• A process of subtracting material from a solid block to create a desired shape.

• A technique used for traditional manufacturing processes involving molds and casts.

• A method of assembling components using adhesives and fasteners.

Artificial intelligence (AI)

• Ability of machines to gather information, perform analysis, and make autonomous decisions.

• A type of software that only follows pre-defined rules.

• A technology that can only perform tasks with human supervision.

• A method for improving human intelligence through training.

Electrons

• Negatively charged sub-atomic particles that orbit the nucleus of an atom.

• Positively charged particles found in the nucleus of an atom.

• Neutral particles that do not have any charge.

• Particles that are larger than protons and neutrons.

Convection

• Transfer of heat through the movement of heated particles in liquids and gases.

• Transfer of heat through direct contact between materials.

• Transfer of heat through electromagnetic waves.

• Transfer of heat through the movement of solid particles.

Chemical etching

• Process that uses the reaction of acids and alkalis to create markings on a metal surface.

• A method of painting using chemical reactions.

• A technique for welding metals together.

• A process for cleaning metal surfaces using solvents.

Absolute temperature

• Temperature of an object measured on the Celsius scale, where zero is absolute zero.

• Temperature of an object measured on the Kelvin scale, where zero is absolute zero.

• Temperature of an object measured on the Fahrenheit scale, where zero is absolute zero.

• Temperature of an object measured on the Rankine scale, where zero is absolute zero.

Creep

• Process where materials experience sudden failure due to excessive loading.

• Process where materials subject to constant loading well below their yield point experience gradual elongation due to plastic deformation and structural degradation.

• Process where materials become brittle at low temperatures.

• Process where materials are subjected to cyclic loading leading to fatigue.

Datum

• Common reference point, surface, plane, or axis from which dimensions are measured.

• A type of measurement used in engineering.

• A specific point in time for data collection.

• A method of calculating averages.

Anions

• Positively charged ions.

• Negatively charged ions.

• Neutral particles.

• Atoms with no charge.

Critical path

• The least important tasks in a project.

• The most time-critical set of tasks in a plan.

• Tasks that can be delayed without affecting the project timeline.

• The tasks that require the most resources.
