Which outcome initially limited efficiency of early Newcomen steam engines despite their scale?

💡 Explanation

When steam filled the cylinder, then cold water injected for condensation, rapid heating and cooling caused cylinder thermal stress cracking because of expansion/contraction differences. Therefore, slower cycle times and lower steam pressures were necessary, rather than other factors, as materials technology was immature preventing higher performance.
