Refer to Figure 11.45. A square footing, 2 x 2 m in size, supports a column load of 300 kN. The soil characteristics are given in the figure. Field monitoring indicated that the foundation settlement was 19 mm during the first 12 months.
a. Estimate the average stress increase in the clay layer due to the applied load.
b. Estimate the primary consolidation settlement.
c. What is the degree of consolidation after 12 months?
d. Estimate the coefficient of consolidation for the pressure range. e. Estimate the settlement in 24 months.
The output shaft, driven by the motor through a worm reduction gear, has a bracket attached on which are mounted two photocells. Complete the closed-loop system so that the system follows the light source.
A 120 V, 60Hz source is connected to a distribution line whose resistance and inductive reactance is .001 Ohm and j0.002 Ohm respectively. A single phase, 100 HP, 120V, 0.85pf motor and a 100 kW, 120 V Heater are connected in parallel.
The below circuit has an output 10 times the difference between the 2 input signals. Show how this could be realised using 2 Operational Amplifiers and 5 Resistors, and provide values of the resistors
find the complete functions, p(t) and w(t) supplied by the element, not just a number, and graph p(t) and w(t). Choose appropriate intervals of time for your graphs. Assume that both v(t) and i(t) are zero for t
