Engineering Help with Homework: Solving a Math Formula

AI Thread Summary
The discussion focuses on transforming integro-differential equations into the Laplace domain for algebraic solving, followed by converting the solution back to the time domain. Key properties of Laplace transforms are provided, including the transformation of functions and derivatives. Participants emphasize the importance of including an attempt when asking homework questions, as per forum rules. Additionally, accessing a Laplace transform table is recommended for solving such problems. The conversation highlights the necessity of understanding both the transformation process and the rules of the forum for effective assistance.

Transform the integro-differential equations to the Laplace domain using known properties.
In the Laplace domain the equations can be solves algebraically.
Transform the solution back to the time domain.
useful properties
$$L\{ \mathrm{f} (t) \}= \mathrm{F}(s)$$
$$L\{ \mathrm{f}^\prime (t) \}=s \, \mathrm{F}(s)-\mathrm{f} (0^+)$$
$$L\left\{ \int_{0^+}^t \mathrm{f} (u) du \right\}=\frac{1}{s} \, \mathrm{F}(s)$$

Per the forum rules that you agreed to when you signed up, homework questions must be accompanied by an attempt. Be sure to include an attempt in any future homework questions you might have.

Also, if you're working on problems where you need to convert differential equations or integro-differential equations (like #1 in the two you posted), you should have access to a table of Laplace transforms. If you do a web search for "Laplace transform table" you should get lots of hits.
 
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...
