More Experimenting

Now then, you saw the engine experiment last week, but this week, I have a different one for you.

Investigate the velocity at different points through a venturi meter.

You just put about 5 or 6 manometers on a venturi meter, and take the values of it, then measure the flow rate. Do some calculations, think bernoulli's, and plot the points on a graph. I think the results would suprise thouse that haven't done this experiment before.

Anyway, I appologise for the lack of posting this week, I've just been a little busy...

Single Cylinder 4-stoke Engine

An experiment... 5 Horsepower engine connected to a dynamo meter with a fuel supply and all the whistles and bells. The engine was throttled at differing rpm and readings of Torque, Exhaust temperature, Air Flow, and Fuel Consumption were taken. Its amazing how interesting this experiment actually is, if you haven't done it, I'd strongly recommend you find the means to do it.

Many things can be found out from engines, espically if you do not normally work with engines.

Anyway, back to work

So then here's a technical question for those in the know,

Have you ever really thought about the Harmonic Motion of a under damped system? Honestly?

I mean it doesn't look hard, however it does look a bit pointless...

Any thoughts?

p.s. Sorry about the shortness of my post, but I really haven't much to rant about today...

Just as a little post filler, here's one of the Scottish National Anthems... Well Scotland doesn't actually have an official National Anthem, but here's Flower of Scotland:

O Flower of Scotland
When will we see
Your like again,
That fought and died for
Your wee bit Hill and Glen
And stood against him
Proud Edward's Army,
And sent him homeward
Tae think again.

The Hills are bare now
And Autumn leaves lie thick and still
O'er land that is lost now
Which those so dearly held
That stood against him
Proud Edward's Army
And sent him homeward
Tae think again.

Those days are past now
And in the past they must remain
But we can still rise now
And be the nation again
That stood against him
Proud Edward's Army
And sent him homeward,
Tae think again.

Anyway, just a little randomness... Of by the way, I'm not actually Scottish...

Formula Student

For those of you that don't know, formula student is a scheme operated by IMECHE, and basically involves a university team building a car and racing it.

Now we hit a problem today, in an effort to make our car smaller and therefore lighter, we forgot to leave a place for the radiator...

So our solution? Hang it off the side and hope for the best... Probably not the best idea but there we are... But the biggest problem? Is getting people to actually get off their a**s and design the thing. I mean the radiator company has cut off all contact with everyone, (Not the best buisness plan), no-one has thought how to attach the radiator to the car, and I seem to be the only one worrying about it!!!!

But thats not the half of our worries, even if we manage to get the radiator to stay on the car, at the moment we don't know how we're going to attach it to the f*****g engine! I mean obviously pipes, but we have no sensible place to put them, they all pass to close to the engine!

Oh well, random rant over...

If anyone wants their say just leave a comment
