Supporting pieces are essential components of many structures, and can include STRUTS, FEET, and TRUSSES. STRUTS are structural members that provide support by transferring loads from one part of a structure to another. FEET are the bottom parts of a structure that provide stability and support. TRUSSES are triangular frames that are used to provide support for roofs, bridges, and other structures. Together, these three supporting pieces form the foundation of many structures.
