AI Thread Summary
The discussion revolves around analyzing the stability of a 40-lb ladder leaning against a 10-lb block on a frictionless surface. Participants suggest starting with a free body diagram to evaluate the forces acting on the ladder and block. The first step is to assume the block is fixed and determine if the ladder will slip. Next, the focus shifts to assessing whether the block will slide or tip over under the ladder's weight. The conversation emphasizes the importance of showing calculations and reasoning to reach a conclusion about the system's stability.

Hi wing911! Welcome to PF! :wink:

First assume that the block is fixed, and check whether the ladder will slip.

The check whether the block will slide, then check whether the block will tip over.

Show us what you get. :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...
