Civil Engineering > GATE 2014 SET-2 > Thermal Stresses
The beam of an overall depth 250 mm (shown below) is used in a building subjected to two different thermal environments. The temperatures at the top and bottom surfaces of the beam are 36°C and 72°C respectively. Considering coefficient of thermal expansion (α) as 1.50 x 10-5 per °C, the vertical deflection of the beam (in mm) at its mid-span due to temperature gradient is ______.
Correct : 2.39 to 2.45
