Discussion Overview

The discussion revolves around the hypothetical scenario of determining the speed and duration a steak would need to travel to cook completely upon re-entry to Earth, considering factors like air friction and heat generation. The conversation includes various approaches to conceptualize this problem, touching on physics principles and culinary considerations.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Mathematical reasoning

Main Points Raised

  • One participant suggests launching a steak into orbit and calculating the necessary speed and duration for it to cook well done, providing initial parameters like mass and volume.
  • Another participant notes that the heat generated during re-entry is primarily due to air compression rather than friction, questioning the assumptions about the steak's aerodynamics.
  • Several participants clarify that the inquiry is not homework but rather a tangent of thought, with some humorously engaging in the discussion about cooking methods.
  • A suggestion is made to drop the steak from a height to measure temperature changes, factoring in air resistance and other variables like marinade type.
  • One participant proposes cutting the steak into smaller pieces to increase surface area, potentially speeding up the cooking process.

Areas of Agreement / Disagreement

Participants express a mix of playful engagement and serious inquiry, with no consensus on the methods or calculations required to determine the cooking speed of the steak. Multiple competing views and approaches remain present throughout the discussion.

Contextual Notes

Participants mention various assumptions about air resistance, the type of meat, and cooking methods, which remain unresolved and could significantly impact the discussion's outcomes.

Let's say you've got this steak and you've found a way to launch it in orbit and propel it back to Earth without any effect on the steak other than friction via air:

How fast does it need to go, for how long (give a few different data points if necessary), to cook well done?

Guys, this is sad; nobody's helped me answer my question. I thought you'd have fun working this one out. Or are all the physicists on here vegetarians? :P

Either way, I suppose maybe I can give some figures to help start you off:
mass of meat: 750 g
volume of meat: Appears to be about 270 cm^3 (270 mL)
 
Is this homework?

Naw, I'm just old fashioned and cook my steak on the grill.
 
For a start, an sr-71 is at something like 500F after some flight at mach 3

Most re-entry heat is the result of compression of the air, rather than friction. How streamlined do you plan to make this steak? :biggrin:
 
No, this is not homework. This is the product of one of the many tangents of my thinking.

How is providing the mass and volume, "an attempt at a solution" ?

You could take the temperature of the steak, then take it to the top of your chimney and dropit and retake the temperature Then work out the hieght needed for it to cook to your liking, taking into account things like decreasing air resistance, type of marinade etc

This will definitely affect the amount of friction due to air resistance.

What cut of meat is this steak? What grade? We need facts.

You could cut up the steak to have multiple orbiting chunks of meat to increase surface area and speed up the cooking process.
