This is a great metaphor for joining the armed forces - the structure and culture of the organisation and some of the people in entrenched positions you will meet during your 'career'.

 

 

 

The test is clearly a way of weeding out people who are too intelligent, will be dissatisfied in the force and will leave immediately after basic training.

 

 

 

It's similar to the way Nigerian princes deliberately have poor spelling and grammar to weed out smart people from their scams.

 



Oh good grief. What a load of utter bollocks.

A small force like the NZDF needs the most intelligent people that it can get.

 

It does. 

 

From my time in uniform for this country, my advice to prospective applicants is 'it won't be like the ads'. If you don't like doing inane nonsense tasks you won't like it.

 

Maybe I'm too cynical but the culture of your typical defence force does tend to be super macho with added alcohol abuse.

Possibly also a measure of how quickly you get through the questions, vs getting stuck in an analysis paralysis on 'how' to answer each question. 

 

In many situations, practical common sense can be more advantageous than IQ.

The correct answer for the slide is Position 1 + Slide A

 

 

The deceptive scale of the victim doesn't help. Position 1 Slide A results in someone just standing there chillin' leaning on an angle going nowhere. I wouldn't be surprised if they have a log of how many times you ran through the practice test and if it factors into the actual result.

As an engineer I would send this question back to be reworked to my satisfaction. My problems:

 

No start point is shown.

 

Question says 'most speed'. It should say 'reach the highest instantaneous speed' or 'reach the (yet to be marked) destination in the shortest time'.

 

The unit size of the person is not shown.

 

No coefficient of friction is given nor is it even declared to be the same on both slides.

 

 

 

Assuming the desired outcome is 'highest instantaneous speed', if one starts sliding at the highest point then the friction created by the position of the person will be trivial compared to the acceleration caused by gravity.

 

Having the person in a more collapsed position such as 2 will give the person more time to accelerate to a higher speed before hitting the very close to 90 degree angle at the bottom at which point they will likely use a bone to stop.

 

 

 

And they can't spell flattest.

Congratulations!

 

You'll commence your position of Private First Class in our Photoshop Signals Division.

 

For your information, the correct answer was to point out that position 1 - to be seen sleeping on duty - is an offence under military law, punishable by court martial with a penalty of up to 20 years imprisonment.  Standing him up so he appears to be awake was not the way things are done around here.

 

(that last part about 20 years for nodding off on the job is true apparently - according to a military lawyer I was talking to the other day)

Another poster PMd me about this. I don't want to reveal too much personal information so let's just say it was two years at the end of the L1A1 era.

so not a lot of time in the service a long time ago? which makes your comments completely relevant today? or for the last 10 years?

 

this do change over the years you know

Uhuh. So the forces are sitting round singing kumbayah now?

 

I don't claim to be an expert on the NZDF but I've had personal experience of it so I'd say my comments are completely relevant.

 

Change you say? How about this 2018 article? https://news.aut.ac.nz/around-aut-news/toxic-masculinity-and-the-military

frankly when you served what 30 years ago?, i would say your experiences are relevant for your time but are likely not relevant today.

 

and you were probably still the lowest rank in the service, its always harder at the bottom.

 

there are plenty of articles outlining what the NZDF is trying to do better.

For the slide question

 

Slide A: the transition from steep to shallow is too brutal
They will hit the end of the steep part and crumple to a mess of broken bones and fall off the slide

 

Otherwise , the TOTAL HEIGHT DROPPED on both slides is the same .
So when at the TOP, the POTENTIAL ENERGY is identical. So converting potential energy into speed : both have to be the same final speed . Assuming we can ignore Slide A's nasty transition from steep to shallow .

So you're saying that a slide of length 100m will generate the same speed as a slide of length 5m, if the drop is the same?  You can't ignore friction, so generally speaking a steeper slide will generate a faster speed

So long as the person doesn't wet themselves (or worse) when being tossed over the edge.

the slide doesnt generate the speed, gravity does. Same total drop in height for both.
the average slope of the 2 ramps is the same . So average friction will be the same ? And final speed will be the same .
I think Newton did these tests with marbles on slopes .

 

Sure, it could be argued that if a slope is too shallow, the person may not move at all (friction).
Im assuming the person has almost frictionless wheels build into their bum. We dont know otherwise .
:-)

 


So The POTENTIAL ENEGERY at the top is the same for both. You cant magically add more energy by fiddling with the slope . Final speed (kinetic engery) at the bottom will be the same (?)

 

 

 

I'll still argue that
on ramp A : alot of energy will be lost where it transitions for steep to shallow . It will be like a crash at the end of the steep part  (crash = energy lost in heat & bruising)

Google Marbles on slopes

 

"When predicting the outcome of a race between identical marbles along differently shaped ramps, most students predicted incorrectly that the shorter path was necessarily quicker (the shorter-quicker belief). When comparing instantaneous speed at 2 points, most students predicted incorrectly that incline speed depended on the slope at that point (the slope-speed belief). A final experiment provides evidence that the slope-speed belief reflects a deeper fallacy regarding the resistance encountered while traversing inclines and lifting objects."

another search result (not written very well)

 

"No matter how the ramp is angled, a marble will hit the ground traveling at the same speed if it starts at the same height each time. “The marbles from all 3 of these ramps traveled the same distance."
