1) The Huber-Hencky-von Mises strength criterion: a) takes the deviatoric component of the second invariant of the stress tensor as reference quantity to assess whether the stress state in a 3D body is inside a safe domain or not; b) is always safer than the Tresca-Guest strength criterion; c) sometimes it can be stricter than the Tresca-Guest strength criterion. 2) Given the following system of beams, the left rotation of the cross section in B, via Mohr's Theorem and Corollaries, yields: a) Bleft = 16 PL² 3 EJ L B E F L/2 L/2 L/2 L/2 3PL² b) Bleft 16 EJ c) None of the others.
