How to represent this system in state space form? where: $$ x' = Ax + Bu \text{ and }y = Cx + Du$$ I am trying to create a state space model based on these equations on simulink, need to find A, B, C and D but like I mentioned, i cannot find the solution when the differentials are not of...

Hello I am reading the book : " Planar Multybody dynamics, Formulation, Programming and Application" An interesting lecture , however is it worthwhile studying these methods for kinematic and dynamic analysis of mechanical mechanisms? I mean There are many softwares on the market which make...

I'm currently looking for possible innovative research topics or ideas, I'm having a hard time to think of one since everything is getting really advance. Thank you.

The image i provided is a section of microcontroller circuit that i used to interface code in C with the I/O port of the microcontroller, in Proteus. I have realized i was only ever told to learn how to measure the voltage and current across the components, Kirchhoff's rules and all, and...

Is there any sort of textbook that covers multiple engineering areas that is at an introductory level?

*** MENTOR NOTE: This thread was moved from another forum to this forum hence no homework template. Summary:: Trying to find transfer functions to design a block diagram on simulink with a PID controller and transfer functions for a water tank system. ----EDIT--- The variables and parameters...

Attempt at question No. 1: ΔD = ∂D/∂h * Δh + ∂D/∂v * Δv ∂D/∂h = 3Eh^2/(12(1-v^2)) ∂D/∂v = 2Eh^3/(12(1-v^2)^2) Δh = +- 0,002 Δv = 0,02 h = 0,1 v = 0,3 ΔD = 3Eh^2/(12(1-v^2)) * Δh + 2Eh^3/(12(1-v^2)^2) * Δv Because the problem asked for maximum percentage error then I decided to use the...

My question relates mainly to mechncial engineering but I guess the general principle may apply elsewhere. Up until now I have mainly been an engineer on the customer side (marine and offshore) , reviewing contractor reports, "sense checking" them and general engineering firefighting and...

I'm in my 2nd semester in the 2nd year of college and I'm very perplexed. I'm learning a lot of physics and chemistry subjects and I can solve them using the mathematical apparatus but I just can't explain them in real life. In chemistry I can understand a few concepts about some chemical...

Are there any practical applications of Laplace transform? I would not use Laplace transforms to solve first, second-order ordinary differential equations as it is much easier by other methods even if it has a pulse forcing function. How can Laplace transforms be introduced so that students are...

In the late 80’s and early 90’s there was the idea of ‘calculus reform’ and some emphasis and syllabus changed. The order of doing things in calculus also changed with the advantage of technology. Similarly in linear algebra, there was a linear algebra curriculum study group that produced some...

Hello, i wasn't in enginnering drawing class since 2 weeks because i was sick and my high school teacher told me to do this homework. This is what I've done so far I did not build the triangle 'cause i am not sure. Please, i just want that someone accompanies me with steps by steps explanation...

Is self-nomination common for career awards in science and engineering? I was under the impression that nomination for awards is only by others but apparently self-nomination is an option too. Any PF member has an experience in this to share?

I am 18 and currently in the middle of taking a gap year from high school to college. I am going to college this fall, and I want to go into college with a better grip on what I want to do than I have now. I absolutely love physics, science, and math. I also have a huge attachment to the idea of...

Is there any way to measure the capacitance of a capacitor indirectly using a multimeter that does not have the option to measure capacitance directly?

I have converted given pressures from bar gauge to bar abs Inlet pressure = 20 - 1.013 = 21.013 bar abs Outlet pressure = 6 + 1.013 = 7.013 bar abs therefore pressure drop (x) x = {p_1 -p_2 \over p_1 } = {21.013 - 7.013 \over 21.013} = 0.6662542236 bar abs Comparing to the chart values for...

Hello everyone. I am from Kolkata, India. This year I have cleared IIT-JEE and taken admission to the Indian Institute of Petroleum and Energy, Visakhapatnam Chemical Engineering which is under the mentorship of the Indian Institute of Technology, Kharagpur. Even though I had to pursue...
