| Shear stress: | (english) Stress acting parallel to an imaginary plane cut through an object. |
| Statically equivalent: | (english) Two force systems are statically equivalent when their resultants are equal. Physically, this means that the force systems tend to impart the same motion when applied to an object; note that the distribution of resulting internal forces in the object may be different. |
| Strain: | (english) The intensity of deformation at a point in an object. See normal strain and shear strain. |
| Stress: | (english) The intensity of internal force acting at a point in an object. Stress is measured in units of force per area. See shear stress and normal stress. |
| Surface force: | (english) A force applied to the surface of an object. |
| Translation: | (english) Motion of an object where the path of every point is a straight line. |
| Transmissibility: | (english) The principle stating that a force has the same external effect on an object regardless of where it acts along its line of action. |
| Weight: | (english) The force on an object resulting from gravity. |
