Re, the train question: It was an electric loco - therefore no steam??

[DickyD]

It's 1930, A train pulls out of the station in Scotland and travels south, it manages to reach a speed of 65 mile per hour. There is a wind blowing from the south at a constant speed of 15 mile per hour, taking all  this information here is the question

what direction does the steam go?

R,

The same direction as the train ? 

[Bunkerbarge]

The steam goes into the cylinders, the smoke is what comes out of the funnel.

[Tug-Kenny RIP]

The steam/smoke/soot/cigarette butts. leave the train vertically whilst the train proceeds at 65 MPH. It would have been left behind by the speeding train had there been no wind, but as it's blowing north at 15 MPH, it takes the debris with it.      maybe!!!

The steam goes into the cylinders, the smoke is what comes out of the funnel.

Not quite,both steam and smoke come out of the stack. Unlike a ship after the steam exits the cylinders it goes to the bottom of the smoke box and inters a nozzle aimed up the smoke stack / funnel to create the draft to pull the smoke through the flues and out of the funnel, this is what gives the puff to the smoke. In fact a properly fired locomotive will have very little to no smoke it will be steam that you see exhausting the stack. In the photo below you can see the steam nozzle at the bottom of the smoke box, the tube that you see above it is called the petticoat pipe (or at least on this side of the Atlantic), between the petticoat and the sheet metal behind this, coupled with the steam nozzle is what causes a venturi in the smoke box and pulls the combustion gases out of the firebox and through the flues. The ring of pipe that looks like a crown is the " Blower", this is used when the loco is standing still to keep the fire going and the water hot by forcing the draft. Also show is a "Supper Heater" (all those little pipes). A supper heater takes the steam from the steam dome and runs it back into the flues to add extra heat, this is called "dry steam" and makes the locomotive more efficient getting more expansion out of the steam. You can tell the difference between a saturated steam locomotive and supper heated one by the slobber on the smoke stack. The saturated loco will have streaks of grunge running down the side of its stack.

[Tug-Kenny RIP]

 Correct.  The lines are treated as whole numbers and the middle is subtracted from the top.

Puzzle 7      find the missing number

                                ?


 

[OMK]

Could it be 251?

[Tug-Kenny RIP]

correct.    From the top, double the number and add 5


Now for sideways thinking
puzzle 7

                             B  C  D  G  ?

[kenthompson]

correct , Bunkerbarge.

[OMK]

B C D G A  (musical notation, maybe??)

[w3bby]

correct.    From the top, double the number and add 5

Interesting, I had it down to plus increasing multiples of 8, 3+8=11, 11+16=27, 27+32=59, 59+64=123, 123+128=251, different action, same result...

[Tug-Kenny RIP]

B C D G A  (musical notation, maybe??)

Very interesting, and well thought out, PMK.  I never thought of this, even though I was in the trade. It is not the path to travel, however.

Answer to B C D G ? N

[Tug-Kenny RIP]

Sorry, but no

[d-jnana]

Here,s one to discuss;

A train traveling due south at 60mph meets a fly traveling due north at 15mph. When the fly collides with the buffer beam, it ceases to travel north at 15mph and starts to travel in the opposite direction at 60mph. Between the time the fly is traveling north, and then south it must be stationary for an amunt of time. At that time it is in contact with the train, which must therefore be also be stationary.
??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
AND
before anybody else says it, whats the last thing to go through the fly's mind?

It's a**e.
