väänetugevus
Väänetugevus is a mechanical property describing a material’s or component’s resistance to twisting under an applied torque. It covers both the stiffness to twist (torsional rigidity) and the strength to withstand twisting before plastic deformation or failure. The concept is especially important for rotating parts such as shafts, drive systems, and fasteners, where torsion can govern performance and safety.
Torsional stiffness, or rigidity, is the torque required per unit angle of twist. For a homogeneous shaft
Väänetugevus can also denote torsional strength—the maximum torque that a member can sustain before yielding or
Measurement typically uses a torsion test, where torque is applied to a specimen and the resulting twist
Applications and design considerations include choosing suitable cross-sections, materials, and heat treatments to achieve adequate torsional
