torsional section modulus
[tɔrˈʃənəl ˈsɛkʃən ˈmɑdʒələs]
nounpl: torsional section moduli
módulo de seção torcional
1. A geometric property of a cross-section that measures its resistance to torsional deformation or twisting stress, calculated as the polar moment of inertia divided by the distance from the neutral axis to the outermost fiber
The engineer calculated the torsional section modulus to ensure the shaft could withstand the applied torque without excessive twisting.
O engenheiro calculou o módulo de seção torcional para garantir que o eixo pudesse resistir ao torque aplicado sem torção excessiva.
2. In structural analysis, the parameter used to determine the torsional rigidity and strength of beams, shafts, and other structural members subjected to torsional loading
A larger torsional section modulus indicates greater resistance to rotational deformation.
Um módulo de seção torcional maior indica maior resistência à deformação rotacional.
This is specialized engineering terminology used universally in structural and mechanical engineering disciplines across Brazil, Portugal, and English-speaking countries. The term is fundamental in civil and mechanical engineering education and is standardized in technical literature and professional practice. No significant cultural variations exist beyond standard Portuguese spelling differences between Brazil and Portugal.
