comment Diagonal of a thin rectangular foil, inertial principal axis?
Why, for example, the second term in the first row is 0?

Thanks a lot for your anser! What do you mean for "body coordinates"?

comment Man on a rotating platform
@Gert I'm sorry, I haven't understood why I don't have to consider the Coriolis force. Man velocity with respect to the platform isn't zero and the platform is rotating. So I have to consider Coriolis acceleration, because Coriolis acceleration makes steer the trajectory but the trajectory has to be straight... thanks for the help

@Gert and what about Coriolis force? it makes steer the trajectory....

comment Man on a rotating platform
@JohnRennie Please read again the question. I don't want the solution. "they have a reason to believe they have made a mistake at all" (in the discussion you posted): it's exactly my case. I'd like to know if what I did (that isn't the solution to the exercise, of course) is conceptually wrong (very likely to me) or not.

comment Acceleration in a non-inertial reference frame
A lot of thanks. About the second question: I have to put $\omega_r$ in $a_{cc}$ and {a_c} if the question is "find ball acceleration in a rotating frame that has angular velocity given by the difference between ball angular velocity and platform angular velocity". Isn't it?
