Question

Thin strips of brass and copper of equal length are used to construct a bimetallic strip. When the strip is heated, due to the difference in the coefficient of linear expansion of the two metals, the brass strip will have a greater increase in length than the copper strip, causing them to bend into an arc with the brass on the outside of the curve. When the temperature of s by 25.8 C, the angle subtended by the two ends of the curved strip is 0 31.09 and the difference in the radius of e of the two strips is L.55 x 103 cm. Determine the original length of the strip. The coefficients of linear expansion of brass and copper are 19 x 10 pec and 17 x 10 5yeC respectively
