If temperature increases by ∆T,

Increase in length L, ΔL=LαΔT
⇒ΔLL=αΔT
Let tension developed in the ring is T,

$\frac{T}{S} = Y\frac{{\Delta L}}{L} = Y\alpha \Delta T\$

⇒T=SYαΔT
From FBD of one part of the wheel,

F=2T
Where, F is the force that one part of the wheel applies on the other part.

F=2SYαΔT
