p10.53 The simply supported beam shown in Figure P10.53/54

consists of a W10 × 30 structural steel wide-flange shape [E =

29,000 ksi; I = 170 in. 4 ]. If w = 5 kips/ft, determine

(a) the beam deflection at point A.

(b) the beam deflection at point C.

p10.57 The simply supported beam shown in Figure P10.56/57

consists of a W530 × 66 structural steel wide-flange shape [E =

200 GPa; I = 351 × 10 6 mm 4 ]. If w = 115 kN/m, determine the beam

deflection at point C.

p10.58 A 25 ft long soldier beam is used as a key component of

an earth retention system at an excavation site. The beam is subjected

to a soil loading that is linearly distributed from 520 lb/ft to

260 lb/ft as shown in Figure P10.58. The beam can be idealized as

a cantilever with a fixed support at A. Added support is supplied by

a tieback anchor at B, that exerts a force of 5,000 lb on the beam.

Determine the horizontal deflection of the beam at point C. Assume

that EI = 5 × 10 8 lb · in. 2 .

p10.59 A 25 ft long soldier beam is used as a key component of

an earth retention system at an excavation site. The beam is subjected

to a uniformly distributed soil loading of 260 lb/ft as shown

in Figure P10.59. The beam can be idealized as a cantilever with a

fixed support at A. Added support is supplied by a tieback anchor at

B, that exerts a force of 4,000 lb on the beam. Determine the horizontal
