2 Physics 1D03 - Lecture 18 The Truss A lightweight structure made of thin members, joined at the ends by pin joints (hinges), with forces applied only at the joints . This means that the members are subject to tension or compression only (no bending). Examples: Steel bridges, hydro towers, crane booms, roof supports in buildings, the supports for the walkway between ABB and JHE, . .. A stable truss is built from triangles.
