Question
The coefficient of linear expansion ′α′ of a rod of length 2m varies with the distance x from the end of the rod as α = α0 + α1x where α0 = 1.76 ×10-5 oC-1 and α1 = 1.2 ×10-6m-1 oC-1. The increase in the length of the rod, when heated through 100oC is :-
Options
A.2cm
B.3.76 mm
C.1.2 mm
D.none of these
Solution
ᐃl = 
Expansion dx = [(α0 + α1x]dx] ᐃT = 100 
(1.76 × 10-5 oC-1 and α1 = 1.2 × 10-6m-1 oC-1. The increase in the length of the rod, when heated through 10oC is :-
