1. (25%) Loads are applied to the ribs of a box beam as shown. (a) Find the shear flows in the skin around rib B, and (b) find the shear flow in the web of rib B. Note that the ribs are stiffened shear webs. Exercise 5.6 At the right is the skin/stringer structure surrounding the rib at section B. Since P2=0, and, by symmetry, I36=0, Equation 5.2.4 reduces to Px(i)=IzPyyiAi. Froen the data on the figure, we obtain P~x(1)=P~xr(4)=50lb/in.P^xr(2)=P~xr(3)=50lb/in. Applying Equation 5.2 .3 to stringers 2, 3 and 4 yields q(2)=q(1)+P~x(2)q~(2)=q(1)+50q~(3)=q~(2)+P~x(3)q~(3)=(q~(1)+50)+50q~(3)=(1)+100q~(4)=q~(3)+P~x((9)q~(4)=(q~(1)+100)50q~(4)=q~(1)+50 Moment equivalence around flange 1 requires (10q(2))10+(10q(9))10=100010+150010 or 2q(1)+150=250q~(1)=50 This together with Equations (a) means q(1)=50lb/in.q(3)=150lb/in.q(2)=100lb/in.q(4)=100lb/in. The directions of these shear flows are as shown in the figure above. They are reversed in direction on the free-body diagram of the rib at the right. To find the shear flow q. in the rib web, we draw a free-body diagram at the left, of rib stiffener 41 .
