Question
A steel rod of length 1 m is heated from 25oC to 75oC keeping its length constant . The longitudinal strain
developed in the rod is : - (Given : Coefficient of linear expansion of steel = 12 × 10-6/ o6)
developed in the rod is : - (Given : Coefficient of linear expansion of steel = 12 × 10-6/ o6)
Options
A.6 × 10-5
B.- 6 × 10-5
C.- 6 × 10-4
D.zero
Solution
Strain
t =
= - αᐃθ = - 12 × 10-6 × (75 - 25) = - 6 × 10-4
t =
= - αᐃθ = - 12 × 10-6 × (75 - 25) = - 6 × 10-4Create a free account to view solution
