Question: 3 stress calculation for a box and i cross section...

Question details

3) Stress Calculation for a box and I cross section beam For the beam shown below (Fig. 6,7 and 8) calcul g and tabulate your data in Table 1 for case 1 and case 2. Apply the following data for ate the stress at the location 1,2, 3, 4 and both I cross section beam and Box cross section beam: Fig. 6: Beam dimension and sensor locations. 6.4 mm 4.5 mm 43 mm 48 mm 101.5 mm 5.5 mm 100 mm 76 mm Fig. 7: Cross section properties of (a) I Cross section and (b) Box cross sections ARC2001 1 Laboratory Session #2 ТРЗ 2018-19 Page 6 of 11
