What are the main safety considerations during design of a pressure relief valve? and how would you go about diagnosing if they are incorrect?
Is the following correct?
Orifice diameter for a fixed pressure - How to diagnose if it wasn't correct?
What effect would a incorrect system...
Pretty cool. Looks weighty though.
The bike doesn't appear to run on gasoline. I can see a pulley in there I think.
Would love that job. People would notice you :)
Do any engineers have problems remembering how to answer a particular question without having to look in a formula book etc?
It happens to me a lot. As a student I worry about this quite a lot. Would like someone who perhaps is in industry to give some input.
Thanks,
I do and I don't really.
I will never fill the vessel I call my brain with all information available in the world. I don't like lots of attention really. Sooo.. It kind of suits me fine.
I am still a student too. I reckon my view on things will change once I got years of experience or...
I'm no good with fluid dynamics. I really am willing to improve can someone point me to what equation I should use for this question. I assume its bernoullis equation? I've drawn a diagram of how I see the pipe.
To make things worse I haven't done fluids in quite a while.
Homework...
I think he is talking about circular pitch. In which case I would think this has to be tangential.
I am trying to find some engineers who might know the exact answer.
Steel = 20x5 - (5x5)= 75 mm^2
timber = 20x15-15x5= 270 mm^2
brass = pi*D^2/4=19.625 mm^2
Those are the CSAs. So from then on what do I do with the tmax and smax values. I didn't quite understand what you mean?
This is so confusing for me sorry.
Can you suggest two textbooks I can find this in? I've got technology of engineering materials and mechanical engineering principles and they don't appear to go in depth with stress.This is unlike anything I've done before and I've been searching for the information for days.
I've calculated...

The Attempt at a Solution
I've drawn the component parts in question. Don't know where to even begin to find this solution (dont have my scanner here too). I am...
I'm pretty familiar with them but can't think of what this resistance could be. I'm thinking its crank resistance through the crankshaft. Is that correct? I've never pull started a mower (all electric here) or kick started a dirtbike :(
I haven't got two deep down with cars either :(
The engine oil. Its cold and not up to temperature.
It seems like the atmospheric temperature is meant to be -20 for this assignment. Yes, I have to overcome that resistance. How do I overcome it though if I don't have a value for it?
Sorry for being so confused!
