Closes.

The two cross over ones cancel out and the two joined by a belt count as one.

Open. Apart from the second and third cog connected by a straight belt, each cog turns the opposite way to the previous one. 15 cogs including the input cog, hence 13 changes of direction and the final cog turns anti-clockwise.

I'm more intrigued as to what's in the box. Fingers crossed it's some 1980 hedge pron.

If /when it does open - is the cat inside dead or alive?

That dead cat is going to be long gone.

What tyres for Jeremy Corbyn's box which might open or close on a conveyor belt. And would it have done the opposite before BREXIT?

At first glance it opens*, but that depends on if the 'string' attached to the lid gets wound** around the spindle of the last cog/sprocket or not. If it does then it opens, if in fact it winds round a bit and then slips off the end and goes slack as it comes back round then the lid will oscillate.

if ** is true then * is true eventually no matter what direction it turns, but if it goes the 'other' way to the image then it would initally close a bit, then open and keep opening as the string wound round the spindle the other way.

Took this picture on a recent flight. This was on the [i]inside[/i] of the door. The button was on the [i]outside[/i].

Did you kick the door open with your "special" shoes? 😉

Is it an exploded diagram of a prototype 15 speed cassette? Only a matter of time..

It closes. I now need to find out. Can someone please built it?

It opens even further and breaks the lid off.

Open, then lift the box up by the lid.

Did they ever fix the £2 coin, so that the cogs on the reverse of that could actually turn?

You seem to be assuming the box isn't superglued to the floor and that the cogs are firmly attached in place.

15 cogs -2 sprockets that are connected by the crossed belt = 13 cogs = 12 changes in direction ? last cog rotates same direction as first ? closes.

Crossed belt is the same as directly connected. It's the uncrossed belt that's made you wrong.

Two cogs joined by a crossed belt rotate on the same direction so they can be thought of as being one cog. So four cogs with crossed belts = 2 cogs. The cogs with the straight, uncrossed belt rotate in opposite directions so can be counted as normal 🙂

It won't take off, and certainly not from LHR, never going to get built this century.

It does neither, it stays still, the first 2 cogs are not meshed and the belt is not gripping.

both

depending on which way you turn the handle in the first place. Just because it's got an arrow on it doesn't mean I have to conform to your rules.

(this answer was basically the same answer given to us on a graduate teambuilding management residential course I went on a few years back. In that case it was build a bridge out of barrels and planks over a 'river', except there weren't enough pieces to do it. There were another load of planks for another task nearby that we were told we couldn't use, but apparently we should have used them anyway because that would demonstrate 'out of the box thinking, a willingness to challenge the rules, and "easier to gain forgiveness than permission". Great message for a group of folks in a heavily regulated part of the chemical industry, and not one the FDA or HSE particularly subscribe to!. I was sorely tempted to ask if his 'rules' allowed me to punch him in the middle of his stupid HR face)

My first company back in Vancouver fell for this whole Organisational Development thing and would churn out endless team building sessions so I can understand where you are coming from.

....did you end up redesigning the nozzle rotate mechanism on the sea harrier? - 6 speed chain upgrade?

Opens. I just traced it with my finger.

As for team building exercises, I remember once being challenged with a group to cross a pond. Stuff at the side of us to build a raft. Sod that. Stop off, wade across, job done. Seems that was the "right" answer.

Turning the handle in the direction indicated will neither open or close it.

The lid will be lifted but as it's already open it cannot be re-opened. neither will it close it as the string will go the wrong way.

It's a test to see if you query the question. As in is the question correct. In this case the question is wrong.
