?

I need a taxi service that is very reliable, and preferably cheap when I am travelling through Auckland this summer. If the taxi doesn't turn up when agreed, then its going to cause lots of issues (such as not being able to do the last item on my itinerary or worse, missing my bus to Rotorua.)

But all of the companies I've googled have awful google reviews. Can anyone recommend a really reliable service?

I'm looking for a flatshare at the moment in the city to which I'm moving to undertake my placement year. Looking through the ads as an undergraduate male, I've been pretty dismayed to find lots of people don't want to live with either undergrads or males.

The other thing I've found alot is that people want their potential flatmates to be single. This isn't really a problem right now, given that I've been single all my life, but after a quick google search I'm still not entirely sure what the implications of the requirement are.

If I'm single now, does that contractually prevent me from getting a girlfriend somewhere in the future?

Can I see girls who aren't officially my girlfriend?

Or does it simply mean I can't have girls over in any capacity during the contract?

A girl who I went to school with 2 years ago but never spoke to. How do I strike up a conversation without it being a little wierd? I feel like a normal cheesy line or compliment would just be wierd.

I have matched with a lovely girl who I went to school with 2 years ago, but never spoke to. I don't believe in leagues - but if I did, she'd be miles out of mine.

How do I strike up a tinder conversation with her. All my usual openers and questions just seem like they'd be wierd, because I already know the answer to most of my questions.

Any advice?

Hi there.

I've been given some concrete column design coursework by uni. To start to design the column we need to find the moment at the top of it.

To do this we have been told to do a subframe analysis.This will require the relative stiffness's of the column and the beams going into it.

The beams were designed in a previous coursework, and are part of the concrete slab. To find stiffness for the beam, we need its second moment of area.

Second moment of area depends on the beams geometric properties - Height of Section, Width of Web, Thickness of Slab, and Effective Length of Flange.

But Effective Length of Flange varies along the beam's length, and thus so will second moment of area.

We haven't been given any maths to deal with this, and I wouldn't know how to find an average second moment of area.

What would you do in my situation?

Met a lovely girl on Wednesday, bumped into her a few times on friday. I asked her for her number, and she gave it to me, but I'm not sure how much that indicates if she likes me as we were both drunk.

I'd want to ask her out for a drink at some point, but obviously I can't set up a date a month in advance (she's gone home to switzerland for christmas.) I want to text her/facebook chat her a few times to gauge and possibly maintain her interest but I don't see how I can keep her interested in me over such a long time?

Any advice?

What method would I use to solve this differential equation and how would I know instinctively to use this method?

The equation is dpheta/dt =k(phetaambient - pheta)

k and phetaambient are constants

Bonus kudos if you fancy solving it.

Hi guys,

I have to find the equation of a plane passing through (1,4,0) and normal to (1,1,1). The answer needs to be in the form r=(point on plane) + lambda(direction vector on the plane) + mu(another direction vector on the plane.)

Finding a point on the plane is fairly obvious, but I don't know how to find the direction vectors on the plane. Can anyone tell me how to do this please?

Hi, I've done some coursework on my laptop with the free student version of autocad. But lots of the marks are for presentation, and I've got educational stamps right on top of my title blocks and borders, and its going to lose me a lot of marks. We have the full version of ACAD at the uni computers. Can I get rid of the stamp somehow on those?

P.S. I've tried the DXFin/out thing on my laptop, as well as saving to dxf and then to dwg - neither worked.

Hi guys. For a radius of curvature equation (you don't need to understand it) I need to find dy/dx of x^3 -2xy + y^3 at (1,1)

I keep getting dy/dx = (3x^2 -2y)/ (1+2x-3y^2) which at (1,1) gives a zero on the bottom, meaning my dy/dx is infinity, so I'm fairly certain I've gone wrong. Can someone confirm this, and show me where I've gone wrong and how to get the correct answer. Wolfram alpha (great website if you don't already know it) thinks the answer should be simply 3x^2 - 2y, but I'm not sure how much I trust it on this one.

Hi,

I'm trying to annotate a drawing but on the lengthways dimensions the text is always upside down. How can I fix this?

Hi.

I've written some code for doing some beam calculations. So far, if you hit run, a dialogue box comes up asking how many point loads you'd like on the beam, and will generate that many random point loads, each at a random distance along the beam.

E.G. if you type in "2," it might say

random_load_magnitudes

=5

=15

random_load_distances

=23

=270

I now want to plot the load at each point along the beam. I have an array called distance_along_beam, which is filled with numbers 1 through 10000 (as the beam is 10m long and we are working in milimetres.) I also have an array called point_load, which is filled with zeros.

I now want to write some code that will replace the zeros at the random_load_distances with the values in random_load_magnitude.

Can anyone give me any help?

I've started with "for i=0:length(distance_along_beam) but can't get my IF statement to work.

Doing some research on possibly trying to climb mont blanc one summer before I graduate uni, and I'm trying to price up equipment (yes, I know I can hire it.) I've got to looking at ice axes. Would I need one ice axe or two? I think I read somewhere that there will be bits of snow that are 45 degrees or steeper that I'd need to climb.

On a side note, if any of you have done mont blanc, feel free to leave me any advice :)

So me and 5 others (we are 3 boys, 3 girls) have a house for next year. Unfortunately there's significant disagreement on how the rooms should be shared.

The rooms are as follows:

Room 1: Ground floor, spacious, room for double bed, well lit.

Room 2: Ground floor, okay size, room for double bed, well lit.

Room 3: 1rst floor, less than okay size, single bed room only, awkward shape, not well lit.

Room 4: 2nd floor, spacious, room for double bed, not well lit.

Room 5: 2nd floor, spacious, room for double bed, well lit.

Room 6: 2nd floor, very cramped, single bed room only, well lit.

Sitting Room: 2nd floor, very spacious, room for double bed, well lit.

As it stands, the girls all say they should have the double beds as they have boyfriend's and we are all single. One girl says she should get a ground floor room as she is still recovering from some walking impediment or other that left her on crutches. And I've suggested that I need a room that has enough room for a desk big enough to do my large scale drawings required for my coursework. The other two guys unsurprisingly seem unenthusiastic about the two smaller rooms.

While I think that one person wanting a ground floor room due to their walking difficulties is fair enough, I think everyone else (myself included) making various excuses to get a big room is a bit lame. I get that it's uncomfortable sharing a single bed with your boyfriend, but it's also uncomfortable having to live in a tiny room all year. The same goes for my large scale drawings (yes it's uncomfortable doing them on a tiny desk, but it's also uncomfortable to get stuck in the tiny room all year just because you're not on a design based course.)

I personally would be happy in any room but the tiny one, and have been trying to think of some fairer ways of sharing the rooms out.

- Get the people in the larger rooms to pay more than those in smaller rooms. Seems an obvious good decision, regardless of who ends up where, but the two girls living in cheaper accomodation than the rest of us at the moment would be bound to complain.

- Bid for the rooms. Again, complaints would be made.

- I suggested swapping the sitting room with the tiny room, making another spacious bedroom. We've all survived fine this year without a sitting room, and while everyone complained at this idea, it's very easy to complain about losing your sitting room when you know that you won't be the one who gets stuck with the **** room. If someone wants to keep the sitting room, they should volunteer for the smaller room. This idea would work best in conjunction with varied rents, to reward anyone who would take the smaller room to keep the sitting room.

Has anyone got any other ideas on how to split the rooms more fairly than everyone just whinging about why they need a big room. Am I being insensitive to those of us in relationships? How would you split the rooms?

Hey guys.

My structures lecturer keeps using I, the second moment of area, in a load of deriving that no one understands. I think I have a reasonable understanding of how to calculate a second moment of area, but not of what it actually is.

So, in layman's terms, what is the second moment of area? How can an area have a moment or vice versa?

And how come small second moments of area lead to bigger stresses in a material (using stress = my/i)?

How do I integrate x / sqrt( x^2 - 9) by substitution?

I could do it pretty easily using an identity if there wasn't a stupid x on top. Any way to get rid of the x using some mathmagical techniques?

Hey.

Doing some gnarly university calculus and I've had a total brain melt down on simple laws of indicies.

I've broken my substitution down to U^4(1 - U^2)

What does U^4 x -U^2 = in this scenario?

Cheers.

If I want to highlight all cells in a collumn that are greater than (but not equal to) 4, and less than or equal to 7, how would I do that. I can't seem to find a way to put two conditions into one rule.

Ps this must work on 010 as it varies from version to version.

I am looking for student housing for next year with my friends. We have found a house we love, but the contract for it has several illegal clauses in it. I have had it checked with several family friends who work for property agencies, and this has been affirmed. Tomorrow I am going to see the landlord to ask him to redraft the contract and to join a TDS (Tenancy Deposit Scheme.)

A flatmate suggested I threaten to report him to the Trading Office, or at least forward them the contract, if he refuses to redraft, as the contract with the current tenants is also likely illegal. Naturally, there isn't much of an incentive to do this unless I use it as a bargaining chip to get him to redraft the contract.

So would this, in the eyes of the law, be blackmail? If I really want the house, but don't want to sign up to some horrendous terms and conditions (such as immediate eviction if rent is more than two weeks late) then what is my best option?
