Problem-1 (20 points) The cantilevered bar shown in the figure is subjected to static loading with $F_x = 75$ lbf, $F_y = -20$ lbf, and $F_z = 100$ lbf. Determine the support reactions at location A. Calculate the internal forces and moments in segments AB, BC, and CA. Identify the type of load (axial, torsion, bending, etc.) acting in each of these three segments.
