Engineering Distance is a problem -- find shear force and bending moment diagram

AI Thread Summary
The discussion focuses on calculating the distance between points F and O in relation to shear force and bending moment diagrams. Participants emphasize the importance of this distance for accurately determining the area of the shear force diagram, which is necessary for constructing the bending moment diagram. The conversation highlights the need to express shear force V as a function of x, leading to the calculation of V(x) at the specified point. The problem remains unresolved, indicating a need for further clarification on the calculations involved. Understanding these concepts is crucial for successfully completing the homework assignment.

This distance because of the we need area of the 2 part of shear force diagram to draw bending moment diagram
 
Start from A and write the shear ##V## in the beam as a function of ##x##. What does ##V(x)## equal at the point in question? Slove for ##x##.

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...
