modulus of rigidity
- noun
- /ˈmɒdʒʊləs əv rɪˈdʒɪdəti/
- Specialized
- A high modulus of rigidity indicates a stiff material.
Examples
-
The modulus of rigidity for steel is much greater than for rubber.
-
Engineers must consider the modulus of rigidity when designing bridges.
-
An increase in temperature can decrease the modulus of rigidity of certain materials.
-
The modulus of rigidity is crucial for engineers.
-
Engineers calculate the modulus of rigidity to ensure materials will withstand applied forces without deforming.
-
The value of the modulus of rigidity helps determine how much a material will change shape when subjected to stress.
-
Materials with a high modulus of rigidity are essential in construction, as they resist deformation well.
Synonyms
A number that shows how stiff a material is

Morphology
The phrase is a straightforward compositional noun phrase: 'modulus' denotes a numerical measure and 'rigidity' denotes stiffness, so 'modulus of rigidity' literally means the measure of rigidity. Although technical, the meaning follows regular English 'modulus/of/property' patterns and is cross-linguistically transparent, so a learner who knows the constituent words can infer the MWE's meaning.
Etymology
Modulus of rigidity uses the word modulus, meaning a 'measure', and rigidity, meaning 'stiffness', so it literally means a measure of how stiff a material is. It tells how much a material resists a 'sideways' push, so engineers know if the material will keep its shape under such forces.
