Question

Structural steel also elongates or expands as temperatures rise. At 1,100 F a 100 Ft long beam can elongate ______ inches

a) 1-2
b) 3-4
c) 5-6
d) 10

Answer 1

Thermal expansion causes a steel beam to elongate when heated, but specific elongation at 1,100 F requires the coefficient of thermal expansion and proper temperature conversion to calculate.

Step-by-step explanation:

When subjected to a temperature increase, structural steel, like many materials, will elongate due to thermal expansion. To determine how much a 100 Ft long steel beam will elongate at 1,100 F, we can use the formula for linear thermal expansion which is ΔL = αLΔT. The coefficient of linear expansion for steel is typically around 12 x 10-6 °C-1, and the temperature change (ΔT) in Fahrenheit must be converted to Celsius. However, as the specific expansion at 1,100 F is not provided here, a precise answer cannot be determined without additional information.
