The phrase "mechanical rigidity" is correct and usable in written English.
It can be used in contexts discussing the stiffness or inflexibility of mechanical systems or materials.
Example: "The mechanical rigidity of the structure ensures that it can withstand heavy loads without deformation."
Alternatives: "structural stiffness" or "material rigidity."
(Her movements, alternating between slouchy naturalism and mechanical rigidity, were only loosely in accord with the music).
In high-voltage transformers, for example, solid insulation provides mechanical rigidity, while oil or other liquid substances contribute to increased insulation strength and serve to remove heat from the equipment.
(It should be noted that these thicknesses are defined by the mechanical rigidity of the lithospheric material. They do not correspond to the thickness of the crust, which is defined at its base by the discontinuity in seismic wave behaviour, as cited above).
Friday's program, "Against Interpretation and Expression: The Aesthetics of Mechanization," emphasized works created during this period of New Objectivity, as it was termed in Weimar Germany, when Romanticism was eschewed for a confluence of neo-Classical lucidity, mechanical rigidity, the sharp angles of African art and American jazz, and sardonic cheek.
Upon ligand removal, heat capacity, melting point, and mechanical rigidity are, as expected, lowered.
The tensile strength characterizations have proven the excellent mechanical rigidity and elasticity of MBF membranes.
The results of this study clearly show the importance of the mechanical strength (rigidity) of the microporous supports in designing high-performance pore-filled membranes.
In SpA (especially AS), other potential risk factors for bone loss occur, such as inflammation and mechanical factors: rigidity of the spine resulting in limited mobility and reduced physical activity due to pain and stiffness.
Neither plastic, though, is suitable for fabricating replacement parts for a lawnmower, a child's bicycle or a vintage car, in which mechanical strength and rigidity are crucial.
An optimum biomimetic apatite ratio was reached to combine good mechanical properties (higher rigidity) and material cohesion.
This study examined differences in drill-tip geometry (point-angle) and mechanical properties (flexural rigidity) between 2.8 mm diameter 2-fluted and 3-fluted surgical drills.
