A beam of rectangular cross-section, as shown in the figure, is made of two perfectly bonded layers of different materials and equal thickness. The Young’s moduli of the two materials are 𝐸1 and 𝐸2, where 𝐸1 = 2𝐸2. The beam is subjected to pure bending. If t = 1 mm, the distance of the neutral plane from the top surface of the beam is ______ (in mm, rounded off to two decimal places).
Answer: 0.80 to 0.85
