Aircraft Structures - ENG2011-N 3. a a. Figure Q3.1 shows a simply supported steel beam of the given cross section. It is subjected to the 2 point loads shown. SOKN 25mm 20 KN 1m 80 mm 2m 1m 4m Figure Q3.1 Draw the shear force and bending moment diagrams. i. ii. Calculate the normal stress due to bending on the top surface of the beam at point C, stating whether this tension or compression. III Calculate the maximum shear stress at point B stating where in the cross section this occurs. b. An element on a different beam is subjected to the stresses shown in figure Q3.2. 30 MPa 20 MP 20 MP T 10 MPa 30 MP Figure Q3.2 Using Mohr's Circle, calculate the principle stresses, stating their orientation relative to the x axis.
