Homework Statement I've been given the above truss and have to analyze it's internal forces as part of the problem, the other part of the problem is to analyze for which lengths members will fail, in what order and for which force F, however this is not the part that I find difficult. In...

I think I've solved it now thanks to your tip Chestermiller! I shouldn't have analyzed the derivatives but just find an equation by integrating both stress equilibrium equations and then combining them, then set this equation equal to the given shear stress values and determine all values of x...

1. Problem statement In a two-dimensional problem, σx=300xy and σy=300xy and τxy=0 at x=y=0. Determine lines of constant shear stress τxy in the x-y plane and plot them for τxy=100, 300, 400. Homework Equations dσx/dx + dτxy/dy + X = 0 [1] dτxy/dx + dσy/dy + Y = 0 [2] At least I think...
