Question 14

The creep rupture envelope are used to

select and predict? Mark all that apply.

safe loads

acceptable temperatures

0.2 pts

O acceptable time of imposed laods/nQuestion 7

The creep is a function of the followings:

polymer properties

exposue to sun light

exposure time to a load

exposure temperature

applied load

0.2 pts

environmmental factors/nD Question 15

0.1 pts

The Boltzmann superposition principle

states that the response of a polymer to a

given load is dependent of the response

of the polymer to any load, which is

already imposed on the polymer.

O True

O False/nQuestion 10

Polymers creep below their yield point

and but recover after the load is removed.

O True
