Which consequence results when friction exceeds design limits in a Stirling engine?

💡 Explanation

Increased friction degrades engine performance because increased thermal losses overwhelm energy input, undermining the Stirling cycle's efficiency. This is due to entropy generation, therefore thermal conversion efficiency decreases rather than enhancements in regenerator, compression ratios or viscosity.
