Question
The figure shows two rods, one made of aluminum [α = 23 × 10-6 (Co)-1] and the other of steel [α = 12 × 10-6(Co)-1] Each rod has the same length and the initial temperature. They are attached ay one end to two separate immovable walls. Temperature of both the rods is increased by the same amount, until the gap between the rods vanishes. Where do the rods meet when gap vanishes ?
Options
A.The rods meet exactly at the midpoint.
B.The rods meet to the roght of the midpoint.
C.The rods meet to the lift of the midpoint.
D.Information insufficient
Solution
As αAl > αsteel so expanision in aluminum rod is greater.
