1.The bucket of the front-end loader shown carries a 3200-lb load. The motion of the bucket is controlled by two identical mechanisms, only one of which is shown. Knowing that the mechanism shown supports one-half of the 3200-lb load, determine the force exerted (a) by cylinder CD, (b) by cylinder FH.
2.Flow occurs in a rectangular channel of 6 m width and has a specifi c energy of 3 m. Plot the q-curve. Determine from curve (a) critical depth (b) the maximum flow rate (c) the flow rate at a depth of 2.4 m and (d) the depths at which flow rate of 28.3 m^3/s may exist and the flow conditions at these depths.
A soil sample was taken from a proposed cut area in a highway construction project and sent to a soils laboratory for a compaction test, using the Standard Proctor compaction procedure. Results of the test are as follows:
A concentrated downward force of 2000 lb. is located 6' from the left support, and a uniformly distributed load of 200 lbs./lin. ft. begins 6' to the right end of the member. What force must be applied at each connection to maintain equilibrium?
An electron has an initial velocity with an x component of zero, a y component of 9.35 km/s, a z component 16.1 km/s, and a constant acceleration of 1.60 x 1012 m/s2 in the positive x direction in a region in which uniform electric and magnetic fi..
The natural ground water table at a site is located at a depth of 2m below the ground water. Laboratory tests reveal that the voidratio of the soil is 0.85 while the grain size corresponding to 10%finer is 0.05 mm.
A cohesionless soil sample was subjected to a triaxial test. The sample failed when the minor principal stress (confining pressure) was 1200 lb/ft^2 and the deviator stress was 3000 lb/ft^2.
Assume that the design temperature and residence time have been established as 1300 degrees F and 0.6 seconds, respectively. The type of burner used in the process requires outside air at a mass ratio of 12:1 (air to fuel gas).
Testing has shown that at a local race track (0.25 in length) racecars have a maximum side friction factor of 0.08. The smallest turn radius on the oval track is 150 feet and has a banking of 20 degrees.
determine the highest real root of f(x)= 0.95x^3 - 5.9x^2 +10.9x-6: (a)graphically. (b) using the newton raphson method(three iterations, xi= 3.5). (c) using the secant method(three iterations, xi-1= 2.5 and xi= 3.5).
What is the minimum distance from the stalled car at which the driver could apply the brakes and still stop before hitting it? Assume coefficient of rolling resistance of 0.013.
The regulatory agency has told the company to maintain a salt level pf no greater then 250 mg/L downstream of the discharge. what should the removal efficiency. (percentage of the salt removed) of a process designed to remove salt from the waste w..
The total length of the hose is 65 m with 200-mm diameter. The exit diameter of the nozzle is 100 mm. Take e/D for the hose as 0.0001. What power is needed from the pump on the water
A compaction test was conducted in a soils laboratory, and the standard proctor compaction procedure (ASTM D698) was used. The weight of a compacted soil specimen plus mold was determined to be 3815 g.
