1. Footings for a structure are to be built beneath a basement slab on a clay soil at a depth of 20ft below present ground level. The groundwater table is 15 ft below the ground surface. The soil-void ratio is about 0.87. If the average bearing pressure on the footings is 2,600 psf, estimate the settlement of 10-ft and 5-ft square footings.
2. What is the factor of safety for the footings in Problem 1 against bearing failure if the clay soil has an unconfined compressive strength of 3,600 psf?
Describe the basic principle of differential GNSS positioning and the difference between real time differential GNSS and post processed differential GNSS.
The shaft diameter is 100 mm. Calculate the largest principal stresses and maximum shear stress that will occur in the shaft.
A 4.00-cm-diameter, 0.80-m long rod of aluminum 7075-T6 is subjected to an axial tensile force with a factor of safety of 1.75. The yield stress and modulus of elasticity of aluminum 7075-T6 are 500. MPa and 210. GPa, respectively.
the pin at B is attached to member ABC and can slide freely along the slot cut in the fixed plate. Neglecting the effect of friction, determine the couple M required to hold the system in equilibrium when.
The Record-a-Song company has contracted with a rising star to record eight songs. The sizes in MB of the different songs are 8, 3, 5, 5, 9, 6, 7, and 12, respectively. Record-a-Song uses two CDs for recording. Each CD has a capacity of 30 MB.

If intake1=0m and intake2=0.5m, find the pressure required to fill the container when h=0.75m at both point 1 and 2. Assume the air is at atmospheric pressure until the water level passes intake 2 and the air follows isothermal compression.
The driver of a car traveling up a 2% grade at an initial speed Vo applied the brakes abruptly and the vehicles slid to a complete stop at an average deceleration of 8 ft/s^2. Was the pavement wet or dry
