at this location. 7 D 0.75 m с 60° 60° 1.50 m Problem # 3 (3.5 points) The steel rod is subjected to the loading shown in Fig. 3. Neglect the bending and shearing behavior of the rod and the size of the couplings at B, C and D. The cross-sectional area of the rod is 60 mm”. (1) Draw the normal force diagram N:of the rod. (2) Calculate the maximum normal stress developed in the rod. Checking the safety condition of the rod follows the theory of maximum normal stress. Take Callow = 230 MPa. (3) Determine the displacements of B and A. Take E-200 GPa. 3.30 KN 3.30 KN 0.50 m 2 kN A 2 KN 8 KN
