Question 1

A standard size plate was used to conduct plate load test in clay soil. For a particular loading intensity, settlement of the test plate was found to be 700 mm. What will be the settlement of a shallow footing of size 3m under same loading intensity? Also, what will be the allowable load for this footing if the ultimate bearing capacity of plate was 150 kPa?

Assume FOS = 3

Question 2

The figure shows the cross-section of an oil pipe with a manometer attached. On the right side of the manometer the manometer fluid is in contact with oil, and on the left side the manometer is open to the atmosphere. The oil has a specific gravity of 0.85 and the manometer fluid has a specific gravity of 1.5. What is the gage pressure at the center of the pipe if hm is 10 cm and h0 is 5 cm?
