Please use the correct method for idealizing the structure! Please use the equations provided.

Given the following idealized wing spar, compute the shear flow distribution in the walls at the largest cross

section $(z=0)$ by following the given steps. Also compute the resultant axial forces on each boom.

Draw the Moment $($M$).$ Shear $($S$)$ and Axial diagram $(N)$

Compute the moment of inertia $I_{}$ at $z=0.$

Compute ${}_z$ of each boom.

Find the force $P_x,P_y$ and $P_z$ of each boom, and the resultant force by filling out the following table.

Find the shear force $S_{y,w}$ and $S_{x,w}$ that is going to be carried by the skin.

Split the problem in two: the open section and closed section and find the shear flow of the open section.

Write down the moment equilibrium equation and find the constant shear flow of the closed section.

Use the superposition principle to find the final shear flow of the wing spar and draw a picture of the final

results indicating the value and the direction of the shear flow. Note: use the sign convention that we used

to report the results using $s$ as shown in Figure $1.$
