derive a symbolic expression for the maximum net conversion efficiency of the cycle,
ηcycle, the ratio of the net amount of work produced compared to the external (not from heat
regeneration) heat absorbed. You may treat the working fluid as an ideal gas. Your expression
may include Tc, Th, and any defined constants.

The Stirling engine (invented in 1816 by Robert Stirling) is a heat engine that produces work
through cyclic compression and expansion of a gaseous working fluid, such as hot air. An idealized
cyclic process, aptly named the Stirling Cycle, for such an engine consists of four steps:
(A) isothermal expansion at the hot reservoir temperature, Th,
(B) isochoric (constant volume) heat rejection to a regenerative heat exchanger,
(C) isothermal compression at the cold reservioir temperature Tc, and
(D) isochoric heat absorption from the regenerative heat exchanger back to the initial state.
