1. a number that represents the size or degree of a physical property
Usage: physics; engineering
2. a positive integer used as a divisor in modular arithmetic
Usage: mathematics
3. a measure of a material’s resistance to deformation under stress
Usage: materials science

Examples

• The elastic modulus of steel is much higher than that of rubber.
• In the equation, we use 7 as the modulus for the calculation.
• The Young’s modulus measures how stiff a material is.
• Calculate 15 modulo 4 using 4 as the modulus.
• The bulk modulus indicates how resistant a substance is to compression.
• Engineers must consider the shear modulus when designing structures.
