P5.8 A solid brass [
E=100GPa
] axial member is loaded and supported as shown in Figure P5.8. Segments (1) and (2) each have a diameter of 25 mm and segment (3) has a diameter of 14 mm . Determine: (a) the deformation of segment (2). (b) the deflection of joint
D
with respect to the fixed support at
A
. (c) the maximum normal stress in the entire axial member.
