Which outcome occurs in early mechanical escapements when iron components experience repeated thermal changes?

💡 Explanation

The rate changes because thermal expansion/contraction alters length via dimensional changes; this modifies period as per the pendulum equation. The period changes rather than permanent deformation, because thermal stress cycles occur and are below yielding of the material.
