Hi everyone,
I'm struggling with another concept - this time plane stress...
From my understanding, plane stress occurs when in-plane loads are applied to a structure such that stress through the thickness is zero. So far, so good. However, my textbooks state that plane stress occurs in thin...
Hi,
I'm trying to brush up on torsion of non-circular sections. Taking a bar of rectangular cross-section as a simple example, my textbooks and various websites all say that the shear stress on the outer fibres peak at the mid-points, and are ZERO at the corners. What I don't understand is WHY...
Hi all, hope you can help.
When drawing Free Body Diagrams (FBDs) is it necessary to consider the stiffness of elements within the structure? I never thought so, until I thought about a simple pin-jointed structure with two truss elements (see attachment). Before considering the relative...
