3. An ASTM A36 structural steel beam 5.00 m long is placed between two rigid supports. When the temperature is 20°C, there is no stress in the bar. Compute the stress developed in the beam if the temperature rises to 45°C. Assume that the proportional limit is 235 MPa. a = 11.7 x 10-6 1/C° E = 207 GPa

Transcribed Image Text:3. An ASTM A36 structural steel beam 5.00 m long is placed
between two rigid supports. When the temperature is 20°C,
there is no stress in the bar. Compute the stress developed in
the beam if the temperature rises to 45°C. Assume that the
proportional limit is 235 MPa.
a = 11.7 x 10-6 1/C°
E = 207 GPa
