Soil with a unit weight of 19.65 kN/m^3 is loaded on the ground surface by a strip load of 1.5 m wide. The strip load is 365 kN/m of wall length. Determine the vertical stress increment due to the strip load and the total pressure both at point 3 m below the center of the strip load.
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.
Two passenger cars are traveling at 65 MPH on a highway moving in the same direction in the same lane. The cars are separated by 25 feet for every 10 MPH of their speed. The coefficient of friction (skidding resistance) between the tires and the r..
What is the peak discharge for an area with the following characteristics The rainfall intensity is 120 mm/hour. Land use Area, m2 Forest 10,000 Single family residential 9,000 Parking lots 5,000
Estimate the effective friction angle for the sand (assume c' = 0). Calculate the sand's shear strength (τf) on a horizontal plane at depths of the 20 ft and 50 ft.
write a computer program that generates a sequence of binomial random variables with parameters n=20 and p=0.3. a) use the inverse c.d.f approach
The selection of the runway for a given day is based on wind at the beginning of the day, and once selected will not be changed for the entire day. The airport has a single peak period each day; this is the hour between 4:00 and 5:00pm.
The line is standard commercial steel pipe 75mm internal diameter. From the column to the pump inlet, the line is 25m long and contains 6 standard elbows and a fully open gate valve.
What power must the pump supply to the system to pump the oil from the lower reservoir to the upper reservoir at a rate of .2 m^3/s. Sketch the HGL and the EGL for the system.
The two shafts in a speed-reducer unit are subjected to couples of magnitude M1 = 18 N · m and M2 = 7.5 N · m, respectively. Replace the two couples with a single equivalent couple, specifying its magnitude and the direction of its axis.
A 55 KG bungee jumper leaps from a bridge. She is tied to a bungee cord that is 12 m long when unstretched, and falls a total of 31 m. Calculate the spring constant of the bungee cord assuming Hooke's law applies.
A 100 gram piece of ice cooled at -20 degrees Celsius is placed in the calorimeter. What is the final temperature of the system, and what mass of ice and water remains
The soil will be excavated from the borrow pit, moistened to increase the water content to 13.5% (assume i will not change the volume of solid mass) and then compacted to a final dry unit weight of 118 pcf.
