Finding flexural compressive stress and tensile stress

AI Thread Summary
To find maximum flexural compressive and tensile stresses, one can analyze the peaks in the bending moment diagram, which indicate where these stresses occur. However, it's important to note that shear force and bending moment diagrams represent forces and moments, not stresses directly. To calculate stresses, one must consider the cross-sectional characteristics of the material in question. The maximum stresses typically correspond to the peaks in the bending moment diagram. Understanding the relationship between forces, moments, and stresses is crucial for accurate analysis.

How would I use a shear force diagram and a bending moment diagram to find the maximum flexural compressive stress and the maximum flexural tensile stress?


I am assuming the peaks at the bending moment diagram is the maximum tensile and compressive stresses? Am I correct?

Also, is it possible to determine the shear stress from a shear force diagram or a bending moment diagram?

Shear force and bending moment diagrams represent quantities of forces and moments, respectively. Forces and moments are not stresses. A bit simplified answer is that stress is the force per unit area. So, if you have some force diagrams, you need to know some cross section characteristics in order to obtain stresses. And, of course, yes, you usually look for the stresses at the points which are peaks of force diagrams.
 
Thank you!
 
Thread 'Have I solved this structural engineering equation correctly?'
Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
