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
