A Light Suspension Footbridge on Salvaged Wire Rope: The Sag-Tension Relation, a Sizing Rule, and the Load at Which the Cable Reaches Its Working Limit

A 30 m suspension footbridge on two salvaged 16 mm wire ropes at a sag ratio of 0.08 reaches its working limit at 43 people, with a 73 kN anchor resultant. Conditions where it should not be built are stated.
