Title: Fuel Tank Capacity Quiz
Post by: Howard Rush on March 17, 2016, 02:42:22 PM
I was contemplating Mr. Taylor's tank problem and calculated what wedge angle on a conventional 1" x 2" stunt tank would give you 1 oz./ inch.  I figure it's 104 degrees, assuming infinitesimally thick tank walls.  Being ever-so-helpful, I recommended a Veco T-21H.

Now for the quiz: How does this lady write backwards on the glass so easily, and why would a man come up with the answer faster than a woman? https://www.youtube.com/watch?v=Mu-Y1xBB-sE

Clarification: The answer to why she writes backwards so easily, not the answer to the math.

I cannot answer your question, but dang she's good!

I get 103 degrees (102.68, etc., actually).

(2 - x) + x/2 = 1.8

x/2 = 2 - 1.8 = 0.2

x = 0.4

angle = 2 * tan-1 (2 * 0.4) = 2(51.34o) = 103o (rounded).

I suspect they flipped the video around.  Otherwise she's both left-handed and able to write backwards.

A man would get an answer quicker because he'd flub his math somehow and round to the wrong number.

If you used more significant figures on the conversion (it's 1.80469), you'd get 104 degrees.

You correctly answered the first question, but see the clarification regarding the second question.

She's on the other side of the glass, writing so that she can read it. If she was nice. she'd write backwards so that we could read it   D>K

Are you sure she's not writing it on a mirror?   D>K Steve

Question 2     A man wouldn't really take the time to figure it out. He'd just pull a number out of the air and expect you to have faith in his accurac   H^^y

Only if it's a one way mirror and we're looking through it. I suspect she is actually using magic, to confuse us.   y1

Steve is still trying to use a mirror to pitch his left-handed props with a right-handed pitch gauge.

I know a little bit about magic and magic tricks.
The first thing we need to understand---NOTHING on a videotape should be believed.

Now then.
If she is right-handed and simply writes on a piece of while being filmed.....al we must do to make this tape is .......
reverse the image and she will appear as a left-hander who is writing backwards.

When I was in tech school I could write fluently in reverse. The teacher graded my papers in a mirror for a while because he thought it was neet but eventually started giving my F's.

I toured a retired Navy carrier in San Diego and they have glass boards to report the location of items and the crew had to write on the back side in reverse so that the commanders could read it from the front side of the glass.

When writing backwards, I find keeping everything under the table, out of sight, helps.

My wife writes backwards as easy as she writes forward. She use to send me notes that I had to hold up to a mirror to read. I still love her anyway.

If it is a mirror image why is her wedding band on the correct, left, hand?

Humm.

Good observation, Mark.  That was meant to be question #3.  I'll go ahead and answer it.

It's Darwinian selection.  She knew that guys seeing the video would be hitting on her and wanted to filter out those who couldn't figure out that the video was flipped.

why would a man come up with the answer faster than a woman?


Because to a man, everything looks like 9 inches?

I know a lot of women that have a ring on their right ring finger.
I'm just saying......

And, if she was my math teacher, I would be intentionally missing some questions to get some extra tutoring.
I'm just saying.

Humm.

It's easy enough to put a ring on a different finger.

It's called Lightboard.

She is writing on a piece of glass.   Look at the other videos of to the side of this one.  How many are old enough that took print shop in high school.   Had to learn to set type with the type upside down and the letters were back ward.  It takes practice.   Have any seen the message in which the only letters in the correct order are the first and last letter,  all others are scrambled.  Just like stunt or any model plane flying, it takes practice.

The buttons on her blouse are on the wrong side, so it is mirror image.  She is right handed.

The physics involved with the Lightboard are interesting.

Just to be clear, the buttons on women's clothing are normally the opposite of men's I think.

Post by: Robert Dible on March 18, 2016, 09:39:23 PM
Yeah, it kind of explains how I helped a young college coed put on her blouse inside out in the dark so many years ago.  The buttons were on the right side and so it felt fine to me, not knowing back then that women's clothes have them on the left.  We didn't notice, but the first person we ran into sure did.

Well done.  That's the answer to question 2.  It's the area of the picture men would see first.

I still think Fred is right and she is prior service Navy.
