Problem 2
The mechanical system consists of two identical steel rods (A = 30 mm?, E = 200GPA,
a = 15x106/°C) and a "rigid" beam AC. The beam is supported by a smooth pin at
B. The nuts at A and C are initially tightened just enough to remove the slack,
leaving the two rods stress-free.
1- Determine the axial stresses induced in rods (1) and (2) if the temperature of
both rods is decreased by 60°C.
2- Determine the (small) angle 0 through which the beam AC would rotate due
to this temperature change.
