Hey fellas please consider helping me with this..
There is a bar of some material that is heated from state 1 to 2 to 3.
If l1 is the length at 1 then we have,
l2 - l1 = l1(1 + a(t2-t1))
l3 - l1 = l1(1 + a(t3-t1))
If, t3-t2 = t2-t1,
Then l3-l2 = l2-l1
But if it is written
l3 - l2 = l2(1+a(t3-t2))
Then,
l3 - l2 > l2 - l1
Why is this..?
