-Two identical concrete slabs lie flat and in contact with each other as shown in Fig. 17-2. If the temperature increases by 40°C, the lower edges opposite the contact edges remained fixed in position, and the lower edges of the contact side remain in contact, at what angle φ will the slabs be tilted? The coefficient of thermal expansion of the concrete is 10 × 10^-⁶/K.
