Q. Which of the following is not part of Tyranny of the rocket equation?

[A] .The destination in space a rocket is headed towards.

[B] .The kind of fuel mix that is being used.

[C] .The size of the payload.

[D] .Geographic location of launching rocket.

Answer: D

The size of a launch vehicle is dictated by 1) The destination in space it is headed towards, 2) The kind of fuel mix that is being used (solid, liquid, cryogenic) and 3) The size of the payload.

– The choice of any two of these variables places severe restrictions on the flexibility of the third, which is popularly referred to as the “tyranny of the rocket equation”.
