Torsion

Tensiones en un eje
Tensiones en un eje
A shaft PQ is twisted when subjected to equal and opposite torques on either side. Consider a section perpendicular to the shaft's axis through an ...
Deformación en un eje circular
Deformación en un eje circular
A unique property of circular shafts is that under torsion, every cross-section remains plane and undistorted, rotating as a solid rigid slab. To ...
Eje circular: Tensión en rango lineal
Eje circular: Tensión en rango lineal
Consider a case when the torque applied to the circular shaft is within Hooke's law limit, so there is no permanent deformation. Now, recall the ...
Ángulo de torsión - Rango elástico
Ángulo de torsión - Rango elástico
Consider a circular shaft of length L and a uniform cross-section of radius r subjected to a torque at its free end. The maximum shearing strain in the ...
Ángulo de torsión - Resolución de problemas
Ángulo de torsión - Resolución de problemas
The electric motor exerts a 700 N-m torque on an aluminium shaft, causing it to rotate at a constant speed. Pulleys B and C experience torques of 300 N-m ...
Diseño de ejes de transmisión
Diseño de ejes de transmisión
The design specifications required for a transmission shaft are the power transmitted by the shaft and its rotation speed. Based on these specifications, ...
Concentraciones de tensión en ejes circulares
Concentraciones de tensión en ejes circulares
Recall the elastic torsion formula, applicable to a circular shaft with a uniform cross-section. Here, it is assumed that the shafts are loaded at their ...
Deformación plástica en ejes circulares
Deformación plástica en ejes circulares
When materials are subjected to stresses exceeding their yield strength, plastic deformation occurs, causing a permanent strain. In the case of circular ...
Materiales elastoplásticos
Materiales elastoplásticos
Within the elastic limit, the maximum stress in a solid circular shaft varies linearly with a radial distance from its axis. As the torque increases, the ...
Esfuerzos residuales en un eje circular
Esfuerzos residuales en un eje circular
In elastoplastic materials, residual stress can develop when the material undergoes plastic deformation due to high shearing stress or large strains. When ...
Torsión de miembros no circulares
Torsión de miembros no circulares
During torsional loading, the cross-sections of the circular shafts remain plane and undistorted since they are axis-symmetric. However, due to the lack ...
Ejes huecos de paredes delgadas
Ejes huecos de paredes delgadas
Consider a small portion of width 'dx' from a thin-walled hollow shaft of thickness 't' subjected to torsional loading. Since the portion ...
