Consider a cantilevered beam which is made of two identical. rectangular sections, a force P is applied at free end. 11) if A and B are not clued together, determine the bending stress distribution at a-a cross section, draw o Chint: each section carries P/ and label the Tout at the outest fibers. * 0.5m a 12) if we weld the two A & B together along the member length. determine the bending stress distribution, draw and laber. m ✓ P=1kw A 181- дет B зст

Calculate the forces in members BE and BD of the loaded truss. The forces are positive if in tension, negative if in compression. Assume F = 7.5 kN, a = 2.5m, b = 3 m, c = 2 m, and d = 2 m. A F Answers: BE= BD = a i i B b E a b O KN KN
