Q.3 The stiffness of the beam shown in Figure 2 is EI = 200 kN m and the section modulus is 35 10 mm. (a) Determine the deflection of B and the bending stresses at A and B. (b) Repeat part (a) but let the translational stiffness of the supports at A and C be 10 and 5 MN/m, respectively, and the rotational stiffness at A be 8 MN.m. Im 5 kN Figure 2
