stress on the rod... can someone help me..?

hello everyone, i am having problems with a tutorial question that is
meant to be handed in on tuesday 28th october 2003, so i was wondering
if any1 out there could help me pls?
The question is as follows:
A 10-cm-long rod of PVC is used to connect two stiff plates that are a
fixed distance apart. The fastening process causes the rod to extend
by 0.15 cm. Given that the elastic modulus of PVC is 3 GPa and
assuming that the material's creep behavior is similar to that
characterized by the data shown in (creep responce in PVC pipe resin
at 20C, creep curve, isochronous stress-strain cruves, isometric-time
curves) estimate the initial stress on the rod and stress after 30
days.
Unfortunately I am unable to add the pictures of these graphs. If
anyone could help me and maybe needs the pictures please email me with
the following subject:
Re: CREEP PICTURE. And I will send you it. Please reply ASAP, thank
you.
