AI Thread Summary
The discussion focuses on calculating torsion, specifically the reasoning behind multiplying the force by a/2 at point C. It clarifies that the force F is divided by 2 to determine the magnitude of each reaction force at support points A and E. Participants express gratitude for the clarification, emphasizing the importance of understanding the distribution of forces in torsion calculations. This highlights the significance of accurately applying the principles of mechanics in engineering problems. Understanding these concepts is crucial for effective torsion analysis.

Summary:: trying to calculate the torsion but couldn´t understand the solution

Greetings
I´m trying to understand why the multiplied the Force by a/2 to find the torsion in te point c
thank you!

They are dividing the force F by 2, not the a distance.
F/2 is the magnitude of each reaction force at support points A and E.
 
thanks a million!
 
You are welcome, Amaelle. :smile:

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...
