A 25m STEEL ROD WITH A CRO6S-SECTIONAL ÅREA OF
1250mm? IS SECURED BETWEEH RIGID SUPPORTS AT
BOTH ENDS. IF THERE IS NO STRESS AT A TEMPERATURE
OF 20°C, E- 200000 MPa.
a. COMPUTE THE STRESS WHEN THE TEMPERATURE DROPS TO
O°C, IF IT HAS A COEFFICIENT OF THERMAL EXPANSION
OF 0. 0000||7 m/m°C.
b COMPUTE THE STRAIN OF THHE ROD IF THE ROD SUPPORTS
YIELD AND MOVE TOGETHER A DISTANCE OF O.5mm
AS TEMPERATURE DROPS.
C. COMPUTE THE STRESS IH THE ROD IF THE SUPPORTS
AS THE TEMPERATURE DROPS.
