Material properties question

1) Three samples of aluminum are subjected to a constant stress and the times required to produce a constant strain of 0.1% during steady state creep at different temperatures are shown in table 1 below.

Temperature (00C) 151 205 258
Time (hours)                100      1.0     0.028

Use this information to determine graphically.

(i) The temperature at which a strain of 0.1% is produced after 10 hours.
(ii) The activation energy for steady-state creep.
