Calculate the stiffener axial loads (lbf) at the end of each beam segment and the shear flows (lbf/in) along each panel edge.

The tapered stiffened beam below is loaded by forces as shown. The beam is assumed to consist of stiffeners carrying only direct stress and shear panels carrying only shear stress. The material used has E = 10500 ksi, G = 3900 ksi, ty = 48 ksi,cy = 38 ksi, sy = 37 ksi. The values of a, b, A, C, E are taken from Question 0.

(a) Calculate the stiffener axial loads (lbf) at the end of each beam segment and the shear flows (lbf/in) along each panel edge. (30%)

(b) Size the beam by determining stiffener areas (in2) and shear panel thicknesses (in). (10%)
