This question is based on Fig. 16.9. An engine operating on an Otto cycle has a maximum peak pressure of \(60 \mathrm{bar}\). If the pressure and temperature at the beginning of the cycle are 1.0 bar and \(300 \mathrm{~K}\) respectively, evaluate the compression ratio that results in the maximum work output from the cycle. What is the thermal efficiency of that cycle? What effect does the peak pressure have on the result?
