Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA In a previous laboratory focused on concrete in compression, we observed that concrete can withstand very large stresses under uniaxial compressive forces. However, the failures observed were not compressive failures but failures along shear planes where maximum tensile forces occur. Thus, it is important to understand the behavior of concrete in tension and particularly its maximum strength...

Tension is a force along the length of a medium, in particular, a force carried by a flexible medium, such as a rope or cable. The word "tension" comes from Latin, meaning "to stretch". Not coincidentally, the flexible cords that carry muscle forces to other parts of the body are called tendons. Any flexible connector, such as a string, rope, chain, wire, or cable, can exert pull only parallel to its length; so, a force carried by a flexible connector is a tension with a direction parallel to...

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Polymeric materials are widely used in civil structures, with uses ranging from very soft sealants to more rigid pipes in water and wastewater systems. The most basic definition of a polymer is a molecular structure with repeating subunits. The term polymer comes from Greek, where "poly" means many, and "-mer" means basic unit. Monomers, or single mers, are the specific repeating units. With...

Surface Tension The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

Myosin-driven contraction pulls on actin filaments and converts biochemical activity into mechanical force. Crosslinking helps organize and distribute the actin network, while microtubules provide additional structural support. The resulting force is not determined by contraction alone; it reflects the balance among filament organization, cytoskeletal support, and resistance transmitted through adhesions and the extracellular matrix.
Cell adhesions provide routes for cytoskeletal forces to pass between the cell and its extracellular matrix. This connection allows internally generated tension to influence the cell’s physical surroundings and lets environmental resistance affect cell behavior. Consequently, tension is part of a mechanically connected system rather than an isolated force within the cytoplasm.
Cytoskeletal tension supports mechanotransduction by converting physical forces into signals that influence cell behavior. Changes in force distribution can affect cell shape, organization, spreading, migration, and division. Studying this conversion helps explain how cells sense and respond to their physical environment, linking mechanical conditions with broader biological outcomes.
Researchers can investigate cytoskeletal tension by measuring or manipulating the forces associated with the cytoskeleton, cell adhesions, and extracellular matrix. They can then examine resulting changes in cell shape, organization, spreading, migration, or division. This approach connects mechanical properties with observable cellular behavior and helps identify how force contributes to regulation.
Cytoskeletal tension influences several coordinated behaviors, including cell spreading, migration, and division. It also contributes to the organization of cells within tissues by linking internal cytoskeletal activity with external mechanical conditions. Examining these outcomes allows researchers to assess how changes in force transmission alter cellular organization and behavior.
These research areas depend on how cells change shape, move, divide, and organize in response to mechanical conditions. Cytoskeletal tension provides a framework for studying those force-dependent processes in developing tissues, repairing wounds, and progressing disease. Measuring or manipulating tension can therefore reveal how cellular mechanics contribute to tissue-level organization and pathological change.
