A distributed load and a point load are acting on the cantilever T sectioned beam as shown in the figure. Point A is at the intersection point of web and flange and located over the flange and B is located at the bottom of the web. a) Calculate and show stresses on differential elements at points A and B. b) Calculate the principal stresses at points A and B. Show results on elements located at these points. c) Calculate the maximum shear stress at points A and B. Show results on elements located at these points. 8 kN/m 200 mm A 20 mm 200 mm B 20 mm 25 kN 110 mm 30 B -1 m 3 m
