The golden gate bridge in san francisco has a main span of length 1.28 km, one of the longest in the world. imagine that a steel wire with this length and a cross-sectional area of 3.10 ✕ 10^−6 m^2 is laid on the bridge deck with its ends attached to the towers of the bridge, on a summer day when the temperature of the wire is 43.0°c. when winter arrives, the towers stay the same distance apart and the bridge deck keeps the same shape as its expansion joints open. when the temperature drops to −10.0°c, what is the tension in the wire? take young's modulus for steel to be 20.0 ✕ 10^10 n/m^2. (assume the coefficient of thermal expansion of steel is 11 ✕ 10−6 (°c)−1.)
