Given the beam shown in Fig. E2, answer the questions below. |275 kN | 275 kN В D 1.5m 1.8m 1.8m Fig. E2 (i) Knowing that o all = 160 MPa and tell = 100 MPa select the most economical metric wide-flange shape that should be used to support the loading shown. (ii) Determine the value expected for the normal stress at the junction of the flange and the web of the selected beam. (iii) Determine the value expected for the shear stress at the junction of a flange and the web of the selected beam. (iv) Draw the stress element, and indicate the normal and shear stresses, for a point located at the junction of a flange and the web of the selected beam. (v) Draw the Mohr's Circle for the stress element determined in (iv). (vi) For the stress element in (iv), calculate the major principal stress o1 and the minor principal stress o3
