In the b-position, on the other hand, the torsion is against the hands of a clock.
In all these cases the torsion and asymmetry of the body are unaffected.
Even if it is only halved, the torsion is reduced sixteenfold.
This is because the torsion varies as the fourth power of the diameter.
It might be supposed that the torsion of the wire would appreciably affect the result.
