1. Refer to Problem 3.12. Assume that the sand is clean and normally consolidated. Estimate the average value of the modulus of elasticity between depths of 20 ft and 30 ft.

2. Following are the details for a soil deposit in sand:

Depth (m)	Effective overburden pressure (kN/m2)	Field standard penetration number,N60
3.0	55	9
4.5	82	11
6.0	98	12

Assume the uniformity coefficient sCud of the sand to be 2.8 and an overconsolidation ratio (OCR) of 2. Estimate the average relative density of the sand between the depth of 3 to 6 m. Use Eq. (3.21).
