A prediction of the Elsasser model is that the shear strain rate changes sign some distance from the fault. Ten years after an earthquake, you find that the shear strain rate changes sign 30 km from the fault. What is your estimate of the asthenospheric viscosity? (You may assume that all the other parameters are the same as in the previous problem.)
If an embankment is placed that adds an average additional stress of 32psi to the clay, compare the settlement from the laboratory consolidation test to the settlement from the estimated field consolidation curve.
Treating the tank of water, the house, and the surroundings as heat reservoirs, determine the minimum amount of heat that must be extracted from the tank of water by any device built to accomplish the required cooling of the house. No other source..

It is known that the velocity distribution for steady, laminar flowin circular tubes (either horizontal od vertical) isparabolic. Consider a 10 -mm- diameter horizontal tubethrough with ethyl alcohol is flowing with a steady mean velocity.15 m/s.
Calculate the initial and final vertical total stress, pore water pressure and vertical effective stress, at the mid-depth of the clay layer, (a) beneath the office block; and (b) beneath the car park
A composite price index for the cost of vegetarian foods called eggs, artichokes, and tofu (EAT) was 330 ten years ago and has averaged an annual increase of 12% since. Calculate the current value of the index.
A homogeneous coarse sand deposit has a water table at 10 m depth. The water coefficient of permeability of the sand is found to vary significantly with height above the water table even though the sand deposit is homogeneous
The casting has a mass of 3 Mg. Suspended in a vertical position and initially at rest, it is given an upward speed of V mm/s in 0.3s using a crane hook H. Determine the tension in cables AC and AB during this time interval if the acceleration is ..
Plot the power input to the compressor and the electric power saved by using a heat pump rather than electric resistance heating as functions of compressor efficiency, and discuss the results.
Stormwater controls are typically designed by civil engineers. Stormwater is collected in pipes below the ground and routed to nearby surface water.
The average rate of flow measured in a gage at the outlet of the watershed was 30 m^3/sec. Estimate the water losses due to the combined effects of evaporation, transpiration, and infiltration due to ground water.
The 3.5-Mg engine is suspended from a spreader beam having a negligible mass and is hoisted by a crane which exerts a force of 40 kN on the hoisting cable. Determine the distance the engine is hoisted in 2.4 s, starting from rest.
