Question

answer the following attachment​

Answer 1

Answer:

3:2

Explanation:

given that

thermal expansion 01:thermal expansion 02=2:3

and no bending of rods

and same inc in temperature

by the formula

Y=F×l/dl×A

we know that

alpha=dl/l×dt

comparing these two we get

Y is inversely proportional to alpha....

hence, Y1:Y2 = 3:2
