A nice little engineering approximation for you folks: π ≈ e ≈ 3

My old boyfriend had pi memorized to some insane decimal place, and, feeling sappy one day, I baked him an apple pi. (a pie with the pi symbol on top) It was pretty amusing, but so not worth the effort in the long run. Posted by Hobbes (Member # 433) on :

Seriously, I'm no good at decoding anything. And that includes subtle hints from females, things like shooting me is probably going to go right over my head. If not I probably wont remember anyways.

Posted by T_Smith (Member # 3734) on :
Hobbes,
Enter in the 10 digits I gave you get the number of places after the decimal point for each one.
Write down each number, and try to decode it, putting in letters for the corresponding number.
Note: if there is a 1, it could add on to the next one. So instead of 1 and 7 it could be 17.
Just a note, of course.
Posted by meltingsnowman (Member # 4559) on :
Speaking of weird transcendental constants...I have a question for any of the geeky here particularly skilled in the areas of math and/or physics...any takers?
Posted by T_Smith (Member # 3734) on :
::looks over at Hobbes::
Posted by HollowEarth (Member # 2586) on :
just ask it. people will come out of the woodwork to answer it.
Posted by meltingsnowman (Member # 4559) on :
Note: this is from a Physics Exam I just took, i have turned it in, so im not cheating or anything like that.
OK, You shoot a ball of mass m, verticaly with velocity 2*Vt, where Vt is the terminal velocty. air resistance is linear such that, Force = -bv and , where b is some constant of drag.
In terms of m, b and g(gravity),
a)find, the Time it takes the ball to travel to its apex,
b)find the height H of the apex
c)find the velocity with which it hits the ground after falling down
What I found interesting is that then solving part c, the ratio between the time up, and the time down, is constant, independent of m, b, or g and the constant is a non terminating, non repeating decimal,(or so it would seem) I was wondering, if anyone else could find the exact value of this constant? like, the natural log of something divided by the natural log of something else?
Stuff to help you if you try, V(t) = Vt*(1-e^(-bt/m))
^ | | Velocity as a function of time, for linear air resistance.
m*g = b*Vt
Posted by meltingsnowman (Member # 4559) on :
oh yea, the constant turns out to be around, 1.568184792... If any of you know that is off the top of your head, so you dont have to work it all out (And, no its not Pi/2, its close, but not really)
Posted by The Rabbit (Member # 671) on :
meltingsnowman, Your solution doesn't work in the limit where b = 0 (no drag). In this case the ration of the time up to the time down = 1. As the drag coefficient increases, this has to change.
Posted by The Rabbit (Member # 671) on :
Ah, I see part of my problem. The initial velocity of the ball is twice the terman velocity. As b goes to zero, the terminal velocity will approach infinity. As a result the time up and the time down will also approach infinity making the ratio of the two an indeterminate form.
Posted by The Rabbit (Member # 671) on :
meltingsnowman, Your answer doesn't work because the sign of the gravitational force doesn't change between when the ball is going up and when the ball is coming down, but the sign of the drag force does change when the ball changes directions. When the ball is going up the solution should be
V(t) = Vt(1-3e^(-bt/m))
When the ball is coming down the solution should be
V(t) = Vt(1-e^(-b(t-tup)/m))
where tup is the time it takes the ball to reach the appex or m ln(3)/b.
so that gives me the height at the apex equals
x = (m^2g/b^2)(ln(3)+2/3);
and I can't get an explicit solution for the time down.

[interjection]Annie, did you know that in Ivan's apartment at Ricks they had the walls of the living room totally covered with white paper? That way, anyone could write whatever they wanted to on the walls. It was chief flirting spot and there was a lifesize cardboard cutout of John Wayne...but the coolest thing was, along the ceiling, like a border, Mike and Ivan were always in the process of writing the digits of pi. It got longer and longer and it was hilarious. Sorry. This thread just reminded me of that. [/interjection]

Posted by Papa Moose (Member # 1992) on :
That took me about 45 seconds. I appreciate your admiration, though.
Posted by meltingsnowman (Member # 4559) on :
Im still very confident of my solution, i checked it many many times for many many hours. The time up you got was right, but the distance wasnt, perhaps you integrated wrong? It should have been H = g(m/b)^2 * (2-ln(3))
He left the time down as an equation you sould solve for T when you had definite values to plug in. I found (by running serveral differnt starting varibles) that the time up and time down were proportional by that constant
