Subject: [Unified-mailman] Fly Day Sign Up
Message-ID: <5.2.1.1.2.20040503153039.00bc1770@po10.mit.edu>


The sign up sheet for Unified Fly Day (this Thursday) is up outside the TA 
office.

Please note:  The first group will leave from MIT as soon as the safety 
lecture is over.
All other groups will have to make their own way to the Alewife T 
station.  We will run shuttles from there to the airfield.  Please plan on 
getting to the Alewife station at least 45 minutes before your scheduled 
flight time so there is sufficient time to get you there.  For example, the 
group that signs up for the 2:30 time-slot should plan to be at Alewife by 
1:45.  We'll be running shuttles approximately every 15 minutes, but you 
should be prepared to wait at both ends... we'll do the best we can with 
the transportation.

lose.

If you were not able to switch into the first group, but you
still want to go, we will video the safety talk and Professor
Coleman has agreed to show it and answer any questions, so 
you should still be able to fly.

Unified students,

In answer to Aaron's question --

In the past I have let the students make their own help sheet for the 
quiz.  However, I would like to try providing one for you instead.  I 
have attached what I intend to provide.

Feedback tomorrow in recitation would be appreciated.  Is this too 
much?  Too little?

See you tomorrow,

- Ian

Ryan,

Correct.  P1 solutions don't answer the question (y-force on the 
vanes).  The force solved for in the solutions is the y-force on the 
mass in the control volume (down -- which you can see by inspection 
since the flow is pushed in that direction).  So the y-force on the 
vanes (what the problem asked for) is equal and opposite to this: up.

Sorry for not catching this.

2pm.  The field in front of 33.  Unified staff vs unified students.  Wiffle
Ball.  'Nuff said.

(Presuming of course that we can play on the field - if they are laying
cement, we'll postpone the game until next week - we'll make a final
decision closer to game time).

After working out a compromise with the men who are working on the new 
runway/path across the field in front of building 33, the annual student 
faculty wiffle ball game will be held TODAY at 3pm
on the field (with the provision that we will be careful and try to avoid 
tripping over their frame).
See you then.
