This is a well-known and very old fact: https://en.wikipedia.org/wiki/Tusi_couple This problem is kinematic. Let's solve it by...

I impose ##C^2## just because it is mechanics and we must consider velocities and accelerations as well.

A motion of the point ##B## relative to a frame ##Oxyz## is exactly the mapping $$t\mapsto\boldsymbol r_B(t)=x_B(t)\boldsymbol...

Now I see what you mean. Then the same question as stated in #14

May I have an example?

ok but this is not the main question of the thread. How do you derive formula of #7 from this: by pure mathematical means? Just bring...

see #7

I just noted that if we want to have a mathematically consistent theory without gaps filled with physical intuition, we have to...

isn't it a verbal description of the formula (*) from the initial post?

Yes, but the main problem is a way from a definition to the Euler formula.

Sure we must just add that this set contains at least three points that do not belong to the same line. Else the angular velocity vector...

I am afraid I do not understand the question

I am teaching classical mechanics for students from mathematical dept. Students demand mathematically rigor definition of a rigid body...

and this is natural because the Lagrange equations do not contain reactions of ideal constraints: all these ##T,T'##. Two Lagrange...

I saw this problem several years ago in a Russian journal devoted to physics olympiads. This problem was discussed there under some...
