Single support; Simple support

A simple support is a type of support that allows rotation and horizontal translation of a beam, while preventing vertical translation.

Appui à rotule ; Hinged support

A ball-joint bearing is a type of bearing that blocks horizontal and vertical translation of a beam, while allowing rotation.

Shear

Shear is a force acting parallel to the cross-section of a beam, causing internal deformations and tangential stresses. Shear can cause excessive deformation, leading to beam failure. Shear resistance is taken into account when designing beams to ensure their stability.

Constraint; Stress

This is the internal force per unit area exerted inside a material due to applied external loads. It measures...
