Question

Mechanical properties of any plastics are mainly dependent on the temperature, force and time of load applied.

(a) True

(b) False

This question was posed to me in an interview.

This intriguing question originated from Processing of Thermosetting Plastics topic in section Moulding with Polymers of Casting-Forming-Welding II

Answer 1

The correct choice is (a) True

For explanation I would say: Mechanical properties relate to movement or breakage of the polymer due to some mechanical variation such as application of load. Mechanical properties are mainly dependent on the temperature, force or load applied, and the duration of time the force is applied. It can also be affected by ultra-violet radiation when used outside.
