Suppose that the 1.3 km span of the golden gate bridge had no expansion joints. Calculate how much longer the bridge would be if the temperature of the bridge increases by 35 degrees celsious

  • science -

    Assume the bridge is made of steel. The coefficient of thermal expansion of steel is 11*10^-6 degC^-1
    A 35 degree C will expand the length by an amount
    35*11^10^-6 = 3.85*10^-4
    of the original length. That would be about 0.50 meters
