1.The wedge is used to level the member. Determine the horizontal force P that must be applied to move the wedge to the right. The coefficient of static friction between the wedgeand the two surfaces of contact is ?s=.25. Neglect the size and weight of the wedge.
2.Compute the energy loss in a 90 degree bend in a steel tube used for a fluid power system. The tube has a 0.5 inch outside diameter and a wall thickness of 0.065 inches. The mean bend radius is 2.00 in. The flow rate of hydraulic oil is 3.5 gal/min.
A 1600 ft long sag verical curve (equal tangent) has a pvc at station 1200+00 and elevation o 1500 ft. the initial grade is -3.5% and the final grade is 6.5%. determine the elevation and stationing of the low point, pvi and pvt.
a storage tank has a diameter of 80 ft, a height of 25ft and contains oil to a height of 15ft. the suction pumps, which can handle 15000bbl/d, are started, but the safety valves are clogged and a vacuum is drawn in the tank.
A concrete beam that is simply supported sustains a uniform live load of 1.8 kips/ft and a uniform dead load (not including self weight) of 1 kips/ft on a span of 24 ft. Determine the layout for a set of No.3 U-stirrups with Fy=60 ksi and F'c=3.5 ..
At 100 km downwind (y=10m), what is the concentration of NOx in g/m^3. The wind speed at the top of the stack with a height of 100m is 6.5 m/s and an inversion layer of 750m Pressure air = 95kPa
The center of gravity of the crane is 10 ft from the pin, and the crane weighs 200 lb. What is the tension in the horizontal cable.
You have two wires connected end to end. Wire 1 is copper and wire 2 is made using a special carbon conductor. Wire 1 has a resistance of 0.215 ohms/ft and is 500 ft long. Wire 2 has a resistance of 0.141 ohms/ft and is 700 ft long.
The pressure in a tire depends on the temperature of the air in atire. When the air temp is 25 C, the pressure gage reads 210KPa. If the volume of the tire is 0.025 m3
the wastwater has a BOD5 of 1200 mg\liter that must be reduced to 200 mg\liter.if the mean cell residence time 5 days and suspended solids concentration of 5000 mg\liter and Y 0.7 kg\kg and kd 0.03 \day determine sludge recycle ratio R
A 110 f t long, 5 in in diameter (f = 0:033) connects two reservoir whose water surface elevations differ by 12 f t. Compute flow rate in pipe.
Course Ab of a five sided traverse runs due north. From the giben balanced interior angles to the right, compute and tabulate the bearings and azimuths from north for each side of the traverses.
you fill a 2-cubic wheelbarrow to the top with aggregate. if the specific gravity of the aggregate is 2.548, and 18% of the aggregate is void spaces, how much does the aggregate in the wheelbarrow weight
