Assuming the two layers to be incompressible, and knowing that the thickness of the first layer (h) is 10 in,
the Young's modulus of the second layer (E2) is 4,000 psi, and the measured surface deflection (w) is
0.01 in, determine:
1. The Young's modulus of layer 1
2. If only a lower quality asphalt concrete is available (E, = 400,000 psi), what should h1 be increased to
in order to attain the same 0.01 in surface deflection?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F85ed0eb4-61da-4d1a-9c74-a52e23182a03%2Fdcc32d62-4529-45a1-a8fa-860587ff4002%2Fr6itovh_processed.jpeg&w=3840&q=75)
