  1. Since the problem statement says "Bar AC" rather than "bar AB and bar BC" are we to assume that it is a single bar composed of the same material everywhere and that the radius is the same everywhere?

  2. When drawing FBDs for the first and second problems, they seem to come out the same, but intuitively, I understand that the second problem has a different answer than the first.

    Why is it that the second pipe has more torque on it (intuitively) than the first?
