PROBLEMS.
= Three plates are welded together to form the section shown. Dimensions of the cross section are b = 5.8 in., d = 17.4 in., a = 2.8 in., and t = 0.5 in. For a vertical shear force of V = 45 kips, determine the shear flow through the welded surface at B. Z B b. 1 b Answer: qв = kip/in.
A beam is subjected to equal bending moments of M2 = 2500 N.m. The cross- sectional dimensions are b = 180 mm, c = 25 mm, d = 73 mm, and t = 7 mm. Determine: (a) the centroid location (measured with respect to the bottom of the cross- section), the moment of inertia about the z axis, and the controlling section modulus about the z axis. (b) the bending stress at point H. Tensile stress is positive, while compressive stress is negative. (c) the bending stress at point K. Tensile stress is positive, while compressive stress is negative. (d) the maximum bending stress produced in the cross section. Tensile stress is positive, while compressive stress is negative 1 (typ) Answer: (a) = i mm i mm S = i mm3 (b) oH = i MPa (c) OK = i MPa (d) Omax i MPa
