Linear Equation
Engineering Fundamentals · Last updated: July 30, 2026 · How this entry was written
Definition: A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable raised to the first power.
Example in context
“The relationship between voltage and current in a resistor is described by the linear equation V = IR.”
“Bir dirençteki voltaj ve akım arasındaki ilişki V = IR doğrusal denklemiyle tanımlanır.”
Where engineers use it
Fundamental in circuit analysis, structural mechanics, and system modeling. Engineers solve systems of linear equations when analyzing networks, trusses, or control systems with superposition principles.
Synonyms: first-degree equation
Antonyms: nonlinear equation
Practice: can you use “Linear Equation” at work?
In a bridge truss analysis, the force balance at each joint yields several linear equations. Formulate the system and solve for the unknown member forces.
Show a model answer
