Question

a steel beam of lenght 5m is heated to a temperature difference of 50 degrees.calculate stress developed in the beam when both ends are fixed and change in lenght when one end is fixed to expand​

Answer 1

Answer:

A steel beam of length 5 m is heated to a temperature difference of 50 degrees. calculate (a) stress developed in the beam when both ends are fixed and (b) change in length when one end is free to expand (a. =11.7x10- / °C, E = 210 MPa). (A) (a) 0 =112.85 MPa (6) 8=0.002925 m (B) (a) = 225.7 MPa (6) 8=0.02925 m (C)(a) =112.85 MPa (6) 6 = 2.925 m D)(a) o =112.85 MPa (6) 8=0.002925 mm

Answer 2

Answer:

0.002925

Explanation:

A steel beam of length 5 m is heated to a temperature difference of 50 degrees. calculate (a) stress developed in the beam when both ends are fixed and (b) change in length when one end is free to expand (a. =11.7x10- / °C, E = 210 MPa). (A) (a) 0 =112.85 MPa (6) 8=0.002925 m (B) (a) = 225.7 MPa (6) 8=0.02925 m (C)(a) =112.85 MPa (6) 6 = 2.925 m D)(a) o =112.85 MPa (6) 8=0.002925 mm
