How Does Acceleration Impact the Angular Rotation of a Beam?

AI Thread Summary
The discussion focuses on the relationship between acceleration and angular rotation of a beam, specifically questioning how acceleration affects the velocity of point A when the fulcrum is at point B. It highlights the need for an equation that incorporates acceleration alongside velocity. Participants express uncertainty about whether acceleration influences the angular velocity and seek clarification on the relationship between linear and angular velocity. The conversation emphasizes the importance of understanding these dynamics in the context of beam mechanics. Overall, the impact of acceleration on angular rotation remains a key point of inquiry.

if b is the fulcrum then Va = Vb + Wab*rb/a
But this taking into account only the velocity mentioned in the question.
I'm not sure what effect the acceleration will have on the velocity of point A.
What equation do I need to use to take the acceleration into account as well?

It says "at this instant", so...
 
Are you saying that it has no effect?
 
Isn't there a relationship between linear velocity and angular velocity?

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...
