9. Force F= 900 lb acts at the left end of the beam as shown. A 8 ft long steel wire of cross-sectional area 0.05 in and modulus of elasticity of 30 106 lb/in is attached at the right end of the beam to prevent motion. Knowing that the wire is stressed below its yield strength, and neglecting the weight of the beam, the elongation of the wire under load is best given by a. 0.0576 in 0.00240 in- 0.0288 in d. 0.0192 in 8290016 42005 FL 23 8=30106 82 8 = AL 472E2 My MJF 828
