Heat a 30 m long straight steel rail anchored only at its ends. The rail curves, forming an arc of a circle 180 m in radius. What was the temperature increase suffered by the trail? (Hint: carefully draw the figure and remember that the length of an arc of a circle is given by the radius of the circle multiplied by the angle, in rad, subtended by the arc). (I need a detailed description please)
