Cross-bridge theory states that actin and myosin form a protein complex (classically called actomyosin) by attachment of myosin head on the actin filament, thereby forming a sort of cross-bridge between the two filaments. The sliding filament theory is a widely accepted explanation of the mechanism that underlies muscle contraction.
Cross bracing between joists or rafters strengthens the members by preventing sideways deflection. This bracing is known by many names such as herringbone strutting, blocking, bridging, and dwanging. Cross bracing on a bridge tower. In construction, cross bracing is a system utilized to reinforce building structures in which diagonal supports ...
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid

A Vierendeel bridge is a bridge employing a Vierendeel truss, named after Arthur Vierendeel, a Belgian engineer who proposed this new bridge girder-type without diagonals in 1896. [ 1 ] Such trusses are made up of rectangular rather than triangular frames, as are common in bridges using pin–joints .

A lattice truss bridge is a form of truss bridge that uses many small, closely spaced diagonal elements forming a lattice. The design was patented in 1820 by architect Ithiel Town .
