Question

(Lo)s=Original length of steel=Lo+0.0010L0=1.001Lo

(Lo = Intial length)

 

I just need this broken down on how it got the answer of 1.001Lo

*22. CD As the drawing shows,
Steel
two thin strips of metal are
bolted together at one end;
both have the same tempera-
ture. One is steel, and the other is aluminum. The steel strip is 0.10%
longer than the aluminum strip. By how much should the temperature of
the strips be increased, so that the strips have the same length?
Aluminum

Step 1
(Lo), = Original length of steel = Lo + 0.0010L0 = 1.001L0
a, = Linear thermal coefficient of steel = 12 x 10-6 °C
aAI = Linear thermal coefficient of aluminum = 23 x 10-6 /°C
AT = Change in termperature of both strips
