Previously, we were discussing the problem with a set of 4 stringers with equal sizes versus a set of 4 stringers with varying sizes.



This leads to the discussion on the Mean Value Theorem. The Mean Value Theorem states that:



$$\int zdA = \bar z A$$

(neglect skin and sparwebs)



Since:
 * V2
 * KY2, K2
 * Q2, Qy

are all independent of 's' (the path), then shear flow will then be independent of q(s)

When crossing a stringer:


 * 1) Find (Yc, Xc)
 * 2) Find Kx, Kz, Kyz
 * 3) Find Iz, Iy, Izy
 * 4) Follow Path (s) to find:

q12, q23, q34

Where q12 is the shear flow in panel 12



where: (y1 is the y coordinate of stringer 1)

where:
