Engineering Glossary

15 This glossary contains field-specific words for the broad profession of engineering terms

This glossary is intended for people who want to explore various engineering topics but who aren't experts in the field. It will familiarize the average person with specific field terms for engineering so that when coming across a study composed by engineers, the reading and comprehension will be facilitated.

Acceleration
Noun
The rate of change of velocity over time.
Example: The car’s acceleration increases when more force is applied.
fr: Accélération
Efficiency
Noun
The ratio of useful output to total input in a system.
Example: Improving efficiency reduces energy waste.
fr: Rendement
Energy
Noun
Energy
Example: Mechanical energy is converted into electrical energy in generators.
fr: Énergie
Force
Noun
A push or pull acting on an object that can cause motion or deformation.
Example: The force applied to the beam caused it to bend.
fr: Force
Friction
Noun
The resistance that occurs when two surfaces move against each other.
Example: The resistance that occurs when two surfaces move against each other.
fr: Frottement
Load
Noun
A force or weight carried by a structure.
Example: The bridge must support heavy loads safely.
fr: Charge
Material
Noun
A substance used to build or manufacture objects.
Example: Engineers choose materials based on strength and durability.
fr: Matériau
Power
Noun
The rate at which work is done or energy is transferred.
Example: The engine’s power output determines its performance.
fr: Puissance
Pressure
Noun
The force applied per unit area.
Example: High pressure can damage mechanical systems.
fr: Pression
Strain
Noun
Engineers calculate stress to ensure materials do not fail.
Example: Excessive strain can permanently damage a structure.
fr: Déformation
Stress
Noun
The internal force per unit area within a material.
Example: Engineers calculate stress to ensure materials do not fail.
fr: Contrainte
System
Noun
A set of interconnected components working together to perform a function.
Example: A set of interconnected components working together to perform a function.
fr: Système
Torque
Noun
A rotational force that causes an object to rotate around an axis.
Example: The motor generates torque to turn the shaft.
fr: Couple
Velocity
Noun
The speed of an object in a specific direction.
Example: Velocity changes when acceleration is applied.
fr: Vitesse
Work
Noun
The transfer of energy when a force moves an object over a distance.
Example: Work is done when a force moves an object.
fr: Travail
