cross-sectional area. Wires are used to bear mechanical loads, often in the form of wire rope. In electricity and telecommunications signals, a "wire" can refer
placing wires on a board. In professionally built wire-wrap boards, long wires are placed first so that shorter wires mechanically secure the long wires. Also

members to provide air between the wire and the lumber and to support the wires. Since air was free to circulate over the wires, smaller conductors could be
