Stress concentrations explained
Stress concentrations occur when stress in a material is increased due to the presence of geometrical irregularities like holes, notches, or sharp corners. These irregularities cause localised “hot spots” where stress is much higher than in the surrounding material, which can lead to failure. Stress concentrations are especially critical in engineering design since they can…

Torsion springs
A torsional spring is a mechanical device that works by storing and releasing rotational energy. It resists twisting or rotational motion and exerts a torque in the opposite direction of its displacement. Unlike traditional compression or extension springs, which store energy in a linear fashion, torsional springs store energy through angular or rotational displacement. Key Features of…
