The assembly shown consists of two A992 steel rods AB and EF and an 6061-T6 aluminum rod CD. When the temperature is at 30° C, the gap between the rod and rigid member AE is 0.1 mm. Determine the following: a) The temperature to which the rod CD just touches member AE such that no axial stress is produced in any rod. b) The highest temperature to which the assembly can be raised without causing yielding (that is, yield strength is not exceeded) in any rod. Assume BF is also rigid and ignore the portion of steel rods within the rigid members. 300.1 mm 25 mm 50 mm D 0.1 mm 300 mm E 25 mm
