Q9.2.2 A 2 m long continuous beam ABC is subjected to two concentrated loads P of 10 kN each at the respective middle of two spans, as shown in Fig. 9.1.2. A Young's modulus E and the Poisson's ratio of beam material are 70 GPa and 0.33, respectively. Determine the total deflection at one of the middle spans, if the cross-sectional dimensions of the beam are given by a width b of 75 mm and a thickness d of 120 mm. (Hint: a loading and supporting arrangement is symmetric). P P A B C x Fig. 9.2.2 1 m y Answers: 0.131 mm (0.121+0.010). 1 m
