Textbook Question
Chapter 6, Problem 6.17P
A 2.0 m × 2.0 m square pad footing will be placed in a normally consolidated clay soil to carry a column load Q. The depth of the footing is 1.0 m. The soil parameters are: c′ = 0, ф′ = 26°, γ = 19 kN/m3, and cu = 60 kN/m2. Determine the maximum possible value for Q, considering short-term and long-term stability of the footing.

Commercial trucks begin to arrive at a seaport entry plaza at 7:50 A.M., at the rate of λ(t) = 6.3 – 0.25t[λ(t) is in veh/min and t is in minutes]. The plaza opens at 8:00 A.M. For the first 10 minutes, one processing booth is open. After the first 10 minutes until the queue clears, two processing booths are open. Each booth processes trucks at a uniform rate of two per minute. What is the average delay per vehicle, the maximum queue length, and the average queue length?
