Solve the statics problems for the equilibrium of arm 2 and the beam.

Here's a complete solution for the statics problems presented.

SECTION A: STATICS

A.1 Equilibrium of arm 2:
Arm 2 is a two-force member because it is pinned at both ends (B and E) and no other forces are applied along its length.
