Hi all, I am after trying to find the plastic section modulus about both local axes (x & y) after having calculated them for the global axes (n & p). Is there a way I can transform global to local using Morh’s circle to evaluate plastic section properties? Attached is the key diagram I am...

Homework Statement I am after finding general geometric expressions for a quarter-circle that is split into two segments along either its domain or range (they are equal). I.e. Taking the circle shown in Figure 1 and concentrating on the upper right quadrant, I am after expressions for the...

Hi Sara, The best way for you to understand how the forces all act relative to point A is to break them down into their rectangular components. When I used to solve these types of problems at university I would always draw the following diagram to communicate to the people marking my...

Hello Everyone, I am after an expression for the torsion stiffness constant of a rectangular hollow section (RHS) with varying wall thickness. I have done some research into finding an expression that allows for four varying wall thicknesses but have not found anything as of yet. The only...

I almost have this solved! What does 'd' stand for in the Tmax formula? Thanks!

Studiot, Thanks for supplying those equations above - you have almost solved my problem. The only thing I am missing is how to find the horizontal component of force (H) in the cable seeing as I have two unknowns in the above equation. Is there another expression I can make use of? Thanks for...

Studiot, I am building in the self weight into the Uniformly Distributed Load (UDL). You are 100% correct in stating that the self weight of the catenary is negligible in comparison to my applied load. So in essence I am creating a hypothetically dense cable. Here is one example: w =...

Hello all, I have yet another mathematical quandary that is robbing me sleep, so I return to gather ideas. This problem (fuelled from self-study) involves the equation of a catenary. The profile of a catenary can be expressed as y(x) = T/w*(cosh(w/T*x) – 1). My inputs into this equation...

Thanks for the clarification. I have been playing with these equations for a short while but am going wrong somewhere. Say, for example, my radius was 10 and I cut the spandrel at c = 4. I have used autocad to produce the exact solution of Ygreen = 3.00853937. No matter what I try I am getting...

Thank you for the reply Kurtz. Should I be taking the value of τ as the radius? I'm interpreting it to mean the value at the top/tangent.

Homework Statement I am after finding general geometric expressions for a quarter-circular spandrel that is split into two segments along either its domain or range (they are equal). I.e. Taking the geometry provided in the sketch below (Figure 1) I am after expressions for area and centroids...
