:
In the design of a hair curling iron one would have
the following limits
-
must be below the safe working temperature of the
material.
-
must not be hot enough to burn the hair.
-
Material usage should be minimized, which affects
the thickness of the PVC.
Design a hair curling iron of PVC satisfying these constraints.
