Engineering Thread

Brian

We really should have our own forum entirely, but I think a thread'll do.

I rather enjoy the relaxed nature of a thread derailment, but in the general public's interest, maybe we should all hang out here.

tl;dr TR032 ARE GO!

where can we use autoCAD on campus? I tried the ICThut, and the computer science labs, but couldn't log on to the computers. Said there was some sort of time restriction on my profile. Does this mean engineers can only use these labs after 7 or something?

What are you using autocad for?

Do you realise you can download the student version (effectively a full version) for free?

Yea, first years dont have full access to the huts. you can go during the time allocated for 1e7.

Kernsr are 1st years allowed upstairs in the red brick building?

dont hold me to this now, but i think it may be installed on the computers in the panoz, down by the lockers in the comp rooms(the ones on the left, on the corridor to the right as you go down the stairs)

i know matlab is on it for deffo

i think only civil engineers do out side lab times

PS were do you get the student version of cad?

Autodesk is just the company that make AutoCAD, Maya, 3DS Max etc.

First year drawing must have been tough this week. There were a fair few still there at 5 when we all turned up to build our bridges

uprooted shane

dare i say it but there was a fair share of nice lookin ladies there too. one in blue looked extra fine

Brian

How specific of you...

Ye made enough noise any ways..

Was at a meeting in M20 and you couldn't hear a thing.

Nice. When we built our we came up with an inverted suspension birdge design made out of bamboo, wish I had a photo of it now.

At 300g your efficiency index is pretty shot..

Although mine is sitting at 297g and has no deck yet.. :-(

deck tends to weight allot. jmccrohan approach of adding reinforcing members to the centre span will pay off diffidence .

Brian

Error calculus makes C++ fun!

#include <iostream>
#include <math.h>
using namespace std;

int main () {
	double num, muppet_percent;
	int num_of_muppets, error;
	
	cout << "How many people are there in your class? ";
	cin >> num;
	cout << "And what percent, would you think, are muppets? ";
	cin >> muppet_percent;
	num_of_muppets = (muppet_percent/100)*num;
	error = (sqrt(pow(0.05*muppet_percent,2) + pow(0.1*num,2)));
	cout << "That means there are " << num_of_muppets 
        << " muppets in your class, &#177; " << error << "." << endl;
	return 0;
}

Crash

Just a point looking at that, and its relatively insignificant from a "you getting all the marks" point of view, but you're going to have problems thanks to switching between ints and doubles. For instance, say you have 100 people in your class, and you believe 64.5 percent are muppets (seeing as you're allowing integer values). That would mean your num_of_muppets int would be 64 - while the double value would be 64.5 - meaning you've rounded down a muppet. Same thing will happen with your error. Better way to do it is to do the calcuation as a double, find out if its an int value or not, then adjust it accordingly.

Of course, that depends on how you want your calculations to work. And if you even consider this, make sure to comment all this stuff in so the marker doesnt just think you're an idiot. :P

Brian

It's correct to round down people though. Anyway, I just did that for a laugh during lunch break, it's not an assignment.

uprooted shane

ah i remember when i used to enjoy programming for the fun! this year is different though, its not so much a class, more a joke!

oh bazza you might know of it allready but this site might intrest you

He wouldn't let us go with 301g, we had to shave a bit off the reinforcing members, so now it is 298g.

Worked quite well in the end. Deflected about 1.9mm iirc when 1.5kg was placed in the middle.

Altho i still dunno how it gained 1g overnight..

Assignment 8:
Create a C++ program to calculate the ammount of muppets in Engineering.

i can see it now.
