An L = 38-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 = 430 lb/ft to wC = 270 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 = 5000 lb on the soldier beam at a = 29 ft. Determine the horizontal deflection of the soldier beam at point C. Assume EI = 3.8 × 108 lb·in.2. Deflection is positive to the left.
