Block diagram Definition and 43 Threads

So i have been solving problems of Newton's Laws of motion and this thing has been quite conflicting for me. I wont complicate my question. I just need one answer. What is the absolute value of normal force on a block of mass M on a wedge? I know it seems a pretty dull question but here me...

This is an analog circuit block diagram of a mathematical pendulum which solves the equation $$ \ddot{\alpha}= -\frac{g}{l}sin(\alpha)$$. I need some help following the signals into and out of the blocks. I think the input to integrator #1 must be ##\frac{g}{l}sin(\alpha)## as well as...

Step 1: I first started by reducing the inside of the block diagram of picture "bd" (the portion with G1 and the negative feedback G2) I obtained G1/[1 + G1G2] I'll call this term "F" Step 2: Then I'm left with two terms feeding into a summing point: F - G3 I'll call this term "K" I can...

Hello I hope someone can help me, as i am kinda stuck for the moment. As you can see, the assignment states that I need to find the poles from the closed loop transfer function. I plan on doing so, by using block diagram reduction method. This is as fare as I've come, and can't come...
