MechDefBod

This force acts perpendicular to the area. It is developed whenever the external loads tend to push or pull on the two segments of the body.

• Normal

• Shear

• Torsion

• Torque

A force that lies in the plane of the area, and it is developed when the external loads tend to cause the two segments of the body to slide over one another.

• Normal

• Shear

• Torsion

• Torque

This effect is developed when the external loads tend to twist one segment of the body with respect to the other about an axis perpendicular to the area.

• Normal

• Shear

• Torsion

• Bending

it is caused by the external loads that tend to bend the body about an axis lying within the plane of the area.
