A rod made of steel with diameter 50 mm is attached to rigid supports at left and right as shown. Initially, assuming P=0, the entire system is free of stresses, but then the right suport is moved by 3 mm to the right whereas the left support remains fixed in space. a) Determine the stress in the bar due to this 3mm displacement. b) After moving the right support, heating/cooling the bar from initial temperatue of To=12°C, and increasing P to P=2kN, in which temperature the system would be free of stress again? A -0.5 m- 0.5 m B A rod made of steel with diameter 50 mm is attached to rigid supports at left and right as shown.
