When the outside temperature is 5.2 ⁰c, a steel beam of cross-sectional area 52 cm2 is installed in a building with the ends of the beam bolted securely to two immovable pillars. in the summer thetemperature of the beam rises to 37⁰c. what is the compressional force fn on the beam? the coefficient of linear expansion of steel 1.1 × 10−5? c−1 and young’s modulus of steel is 2 × 1011 n/m2. answer in units of n.
