A steel rod of length 1m is heated from 25°c to 75°c keeping its length constant.The longitudinal strain developed in the rod is:(steel:12 X 10^-6/°c)
"6X10^-4" ; "-6X10^-4" ; "0"
please help me as soon as possible by explain this.
To find the longitudinal strain developed in the steel rod, we need to use the formula:
Longitudinal Strain = (Change in Length) / Original Length
Given that the length of the steel rod is constant, there is no change in length (ΔL = 0). Therefore, the longitudinal strain developed in the rod is also zero.
This is because the steel rod expands when heated, but since its length is constrained and does not change, there is no elongation or compression, resulting in zero longitudinal strain.
So, the correct answer is "0".
