Hey guys,
I’m on the lookout for some online courses I can dive into during my downtime. I’m really into mechanical design – think anything from piecing stuff together, working out dynamic mechanisms, picking the right motors, to designing brackets that actually fit like they’re supposed to...
Hi, well that is really my question .
How the hell I solve this FBD??
BTW, you guys asked for numbers, but can we solve it parametrically ? I'm not sure how the numbers help, and all I need to understand actually is indeed how to make this FBD. That is my question.
If you say it is important I...
Hi Guys, please please assist me!
I need to pick for a project at my work linear carriages which should work at this configuration :
As you can see, there is a piston which moves the plate on 4 bearings from the side (yes, I know, not the best configuration, but that's what we have given the...
You are absolutely right in all accounts. Funny thing is that I wasn't aware of this as well, being a Mechanical Engineer with a diploma hah.
Thanks a lot!
Hi,
So,I'm helping a guy with his mechanical engineering homework.
The problem is that the guy is so off, he doesn't even know the name of the subject.
And honestly, I having a hard question finding out what this question is about.
I need to proove the Zb=h^2/3 thingy. I have no idea what this...
So,I started to work in crane production industry . I suppose to choise the correct IPE profile for my jib crane (which looks like this one http://www.eotcranes.org/wp-content/uploads/2015/05/Post-Mounted-Jib-Crane.jpg ) , but no one in engineering department wants to explain me how to choose...
I studied Linear Algebra ,and that's overcomplicating things .
All I am asking : How do I solve in Matlab something like this :
[A] [1 0 1 0][M]
[V] [0 1 2 0][N]
[0]=EA/L [0 1 2 0][Q]
[D] [0 4 5 4][L]
Where I know some of the variables in the first matrix...
It's part of finite elements analysis.
All I need is to solve F=Ku,K is [12x12] matrix .
Some of the members of u are zeros ,some members of F are known forces . K is all known .
How do I solve F=Ku in that way ??
Thanks in advance.

Here is the problem :

I've tried solving this inequality but alas,nothing...It's an exam question for my student,and for my great shame,I have no idea how to solve it :(
Heh,thanks for replies guys,it was just badly formed engineering task,I asked once again and was told that the system just does not have to be efficient to high degree.
I've chosen V-belts as they have efficiency of 70-99 percent.
Anyway,thanks for the detailed responces,this is very appreciated!
Howdy all!
In some project I do,I need to design belt transmission,now the tricky part is:
On the output of the belt,I have wheel that needs to turn at 700 rpm,and I need to deliver power of 6KW.
Now the weird question:I need to design the belt transmission so I will have 20 percent power loss...
So,I got this vector of input data in Matlab,which is vector of approx 1x25000 length.
I have frequency responce function attained by different estimators (H1,H2,Arx).
Anyway,my FRF is also a vector of 1x129 length.
Those two are different sized vectors.How should I find the output data...
Homework Statement
So ,here is the question : The structure is shown in the picture.
All I need is to find the angular velocity of telescopic arm BC ,in this current position.

It's not my schoolwork project,we are team of students who make a car.I don't get any homework credit for solving this problem..More over,our academic teachers tell us to use any information source available.
Anyway,those links do not say much to me,specialy the first one which is very generic...
