I'm trying to compress a gas at max 300 psi. I'm making an air tank that will move a small turbine to make electricity. The problem, as I found out, is that 1L at 300 psi is not that much air and I need it to run for about a minute. When I fill my tank with air from a compressor, i run out of...
Not getting really far on this. I do not understand why this forum makes a point on being so cryptic with the help provided. I have no doubts on the good intentions of its members but after asking a couple of questions related with homework I couldn't help get frustrated for the meager hints...
Besides |U||V|Sinα wouldn't that be |U x V|? which confuses me too because it means that |U||V|Sinα = |U x V| = U x V
I'm working on it and post if there is any or not much progress...
Homework Statement
I need to proof that VxU=(determinant) starting from VxU=|V||U|sinαe
Homework Equations
VxU=|V||U|sinαe and what I'm aiming to is VxU=(uy⋅uz - uz⋅vy)i - (ux⋅vz - uz⋅vx)j + (ux⋅vy - uy⋅vx)k
The Attempt at a Solution
U x V = |U||V|Sinαe
(U x V)^2 = |U|^2|V|^2 cos^2α - 1 e
(U...
Hi there, I would like to hear your opinion on taking 15 credits vs 12 credits. All the classes are engineering classes worth 3 credits hours. The list goes as follow:
INTRO TO ENGINEERING DESIGN (Lecture)
INTRO TO ENGINEERING DESIGN (Laboratory)
SOLID MECHANICS (Lecture)
NUMERICAL...
That is very cool Dave.
It might have a filter like most cameras but I'll check the specs.
I just found this diode but the beam angle is way too narrow. I would need something with a wider beam.
This is what you mean right?
What kind of software could make sense of the IR signals?
Thanks a lot for your suggestion Dave.
That is what I'm thinking but I'm quite ignorant of the different ways I could achieve it.
I was told that to see it could be a good solution to it. My concern is the background (outdoors) and range. How many pixels needs the magenta be to be detected...
So I've been researching whatcould be the sensor/s that would do what the picture depicts:
I have camera A behind camera B. What I'm trying to achieve is: to point the position of camera B when B passes on the field of view of A.
When B pases in front of camera A the Screen of camera A will...
Not at this point on the assignment. But what I mean by most efficient is whichever layout makes the compression and tensions forces to a minimum. I've been looking at the loop function but I'm not really sure how to use it yet.
To reinstate the problem as Mr Bernhardt suggested,
I want to...
Hello everyone,
I'm attempting to come up with a way to calculate the most efficient 7 members truss layout using Scilab.
The assignment is to make a highway sign support.
It has to be L shaped and the truss system is only for the top horizontal part.
Two supports.
The sign is hanging at the...
Homework Statement
∫sec(x)tan(x)+x/(x^2+1) dx
The Attempt at a Solution
I replaced sec and tan by 1/cos(x) and sin/cos(x) then end up with sin(x)/cos^2(x)
then I replace cos^2 x by 1-sin^2 x then I don't know where to go. the second part of the equation works with u substitution.
I just...
