An L = 23-ft-long soldier beam is used as a key component of an earth retention system at an excavation site. The soldier beam is subjected to a soil loading that is linearly distributed from wA = 410 lb/ft to wC = 290 lb/ft, as shown. The soldier beam can be idealized as a cantilever with a fixed support at A. Added support is supplied by a tieback anchor at B, which exerts a force of P = 4500 lb on the soldier beam at a = 18 ft.
