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-560 lb/ft to wc-240 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-4600 lb on the soldier beam at a - 29 ft. Determine the horizontal deflection of the soldier beam at point C.

A prestressed concrete beam supports a live load of 4 kN/m over a simply sup- ported span of 8 m. The beam has an I-section with an overall depth of 400 mm. The thicknesses of the flange and web are 60 and 80 mm respectively. The width of the flange is 200 mm.
