How good is YOUR mechanical knowledge?

[Edbear]

86%, but you only got one shot at the questions, so I couldn't change an answer when I realised I'd got one battery question wrong!

Still, I reckon I should have done better. The atmospheric question is as old as the internal combustion engine...

[raster]

90%, 450 Points, not too bad, got the balloon and sucky questions wrong, if you want to see progress, click icon botton left, show/hide TOC.

[Slingshot]

No such thing as sucking

You're right, the pressure is lower in my wife's mouth compared to the pressure around my cock.

94%, and I'm not a mechanic. I'm an out-of-work IT contractor. Perhaps I should think about a career-change.

Except they forgot the main mechnics question:

Q51. You disassemble and then reassemble a complicated mechanical object. Expressed as a percentage of the toal number of discrete components in the object, how many is it acceptable to have left lying on the floor when you've finished.

a) 0%
b) 5%
c) 10%
d) 50%. She'll be right, mate!

Commonly known as hedge bolts...cause you throw them in the hedge.


I can't understand how I got the attached one wrong:

I can't understand how I got the attached one wrong:

With both switches closed the middle bulb is by-passed by the RH switch, current will flow through the switch rather than the bulb.

[skidMark]

got to question 20 and realised i had fucked up question 15 or 16 or sumthing..so closed it ...

With both switches closed the middle bulb is by-passed by the RH switch, current will flow through the switch rather than the bulb.

I thought it would flow through both the switch and the bulb as the middle bulb and that switch are in parallel.

It will - but so disproportionately in favour of the switch that you won't notice the bulb.

There isn't if you have one pulley, no matter which direction you pull you are lifitng the same weight. There is only a mechanical advantage when you have multiple pullleys an the ropes setup in teh right arrangement.

I can't see the quiz (no bloody flash for 64-bit yet) but you can gain an advantage with one pulley - fix it to the load, and tie the end of the rope that you're not pulling to the structure above.

Electricity always follows the path of least resistance.The switch acts as a short circuit/conductor.

Aha, of course. Like water.

Inversely proportional to the resistance - which is low, but not zero, for the switch (and wires either side of it).

[howdamnhard]

Exactly right.

86%. Not bad for a graphic designer...

Questions they should have asked:

If you cross thread a bolt, will it 'get better' by continuing to turn?

If the apparent torque required when tightening a bolt reduces, does that mean you're getting stronger?

Is electricity the work of the devil?

If an electrical component starts to emit smoke, should you go to Repco for a new can for smoke to replace the smoke it's losing?

Do rotary engines suck?

Do scooters travel faster when going with the earth's rotation?

Yes.

Trouble with yer torque wrench dude?
Standard practice is tighten until it strips and then back it off a quarter turn.

I can't understand how I got the attached one wrong:

The second switch shorts out the middle bulb. Current takes path of least resistance, so goes thru switch, not bulb...


Errk - just saw ho many others had replied to that...
