A strut and cable assembly ABC supports a vertical load P = 18 kN. The cable has an %3D effective cross-sectional area of 120 mm?, and the strut has an area of 250 mm?. (a) Calculate the normal stresses O and ab O in the cable and strut, and indicate bc whether they are tension or compression. (b) If the cable elongates 1.3 mm, what is the strain? (c) If the strut shortens 0.62 mm, what is the strain?

Question
A strut and cable assembly ABC supports a vertical load P = 18 kN. The cable has an effective cross-sectional area of 120 mm², and the strut has an area of 250 mm?. Cable 1.5 m (a) Calculate the normal stresses Oh and ab O in the cable and strut, and indicate bc whether they are tension or compression. Strut 1.5 m (b) If the cable elongates 1.3 mm, what is the strain? 2.0 m (c) If the strut shortens 0.62 mm, what is the strain?
