Question

(d)
The difference between the length Li of brass rod
and a steel rod of length L2 is constant at all
temperatures. The coefficient of linear expansion
of brass and steel are alpha1 & alpha2 , respectively. Then
(a) L = L2
(b) Li Q2 = L2
(c) L (1 - 1) = L2 (1-02)
(d) L (1 - 2) = L2 (1-1)​

Answer 1

Answer:

The difference between the length Li of brass rod

and a steel rod of length L2 is constant at all

temperatures. The coefficient of linear expansion

of brass and steel are alpha1 & alpha2 , respectively. Then

(a) L = L2

(b) Li Q2 = L2

(c) L (1 - 1) = L2 (1-02)

(d) L (1 - 2) = L2 (1-1)
