ІВ B The rigid horizontal bar ABC of negligible weight is connected to 2 rods. The coefficient for thermal expansion for rod B is 2 times that of rod C but rod C is longer than rod B. Draw the FBD of the system when temperature of the system is reduced. Be sure to indicate distinctly the deformations due to temperature or total deformations due to forces for both rods, as well as the net or total deformation for each rod (exaggerate as need to clearly see where these deformations are). Then write the relevant deformation equation based on the FBD).
