AI Thread Summary
The solution presented for the mechanics of materials problem requires clarification, particularly regarding the shortening of bar A-B. It should include two terms: one for the un-drilled section and another for the drilled section, which involves an unknown dimension. The shortening of bar B-C is deemed acceptable. Accurate calculations are crucial for the upcoming exam. Ensuring these adjustments will enhance the correctness of the solution.

Your shortening of bar B-C looks ok.
Your shortening of bar A-B should contain two terms: one expression for the un-drilled portion and one expression for the drilled portion. The latter term will contain your unknown dimension.
 
thank you a lot !

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...
