Two precast concrete sections of 224 [m] each are placed on a drawbridge, in such a way that they are embedded at their ends, where at 16 [° C] there is no space for possible expansion ( linear). There is a temperature increase of ΔT = 27 [° C] during a very hot summer day, causing both sections to rise in the center as a result of their linear deformation. 1) The value of the height, with respect to the horizontal, at which the central part of the bridge rises, in meters and to the nearest tenth, is: R:
