Does Leather Shrink When Wet, or When You Apply Heat or Dryer?

SpletWhen the strip is heated the brass expands more than the iron so the strip beds. It is used in devics such as fire alarms and circuit breakers to either make or break contacts in an electric circuit. The differences in expansion and contraction are even more visible in different states, again due to the amount of force holding the atoms ... SpletIt's heated and air is blown into it while it sits in a bottle shaped mold. Then it's quickly cooled to lock the plastic into that shape. The stretching creates residual stress in the plastic.
