Station 0+00 is at BM which has an elevation of 508.97. During the survey, the backsight (BS) to this monument is recorded as 10.92. The level is then turned to sta 1+48, and the foresight (FS) is recorded as 13.14. Next the level is moved to a new position between STA. 1+48 and sta. 2+76. Now the BS is 8.78 and the FS is 5.25. Once again, the level is moved to a new position to complete the survey. This time, the level is moved to a point between sta. 2+76 and sta. 4+12. At this point the BS is 18.22 and the FS is 7.94 18. what is the elevation for sta. 2+76 a. 506.75 b. 510.28 c. 520.56
d. 528.50 19. what is the HI when the level is positioned between sta. 2+76 and sta. 4+12? a. 506.75 b. 510.28 c. 520.56 d. 528.50 20. which station has the highest elevation a. sta. 0+00 b. sta. 1+48 c. sta. 2+76 d. sta. 4+12
An element of material subjected to a plane strain has a strain epsilon x of 280x10^-6, a strain epsilon y of 420x10^-6 and an engineering shear strain gamma xy of 150x10^-6.
5 Kg of water at 1.2 MPa, 120oC is contained in a frictionless piston-cylinder device. The water is heated until its temperature reaches 250oC. a) a)Determine the work performed in kJ
A cast iron water main 14m long of 600 mm inside diameter and 30 mm wall thickness runs full of water and is supported at its ends. Calculate the maximum stress in the metal if density of cast iron is 7200 kg/m and that of water is 1000 kgm.
what is the pressure applied to the soil under the above load. How does this compare with an allowable bearing capacity of 100kPa. Does this allow for a reasonable factor of safety.
Determine the required thickness of the pipe wall if the operational pressure head (pressure head in the pipe under regular flow conditions) is 40 m and if the flow control valve on the downstream end closes suddenly, developing a water hammer in ..
A ssume that one half of the energy incident on the collector goes to this reservoir, which, in turn, serves as a source for a heat engine. If the temperature of the atmosphere is 70 F,
The roadway to be constructed is 3 miles long and 60 feet wide. • The following pavement design specifications have been issued: - Base coarse: 6" DGA - Stabilized base: 4" - Bottom coarse of asphalt: 3" - Top coarse of asphalt: 2"
The roadway is to be widened which will require a slope face cut at a steeper angle. Assume zero cohesion along the joints. What engineering parameter must the joint surfaces possess (magnitude) to be stable
A hoist mechanism is attached to the back of a pickup truck. The crate being moved by the hoist shown below weighs 200 lbs. Note: Point A is directly above point B and the vertical distance between points A and B is 16 inches.
A vane, 10 cm long and 8 cm in diameter, was pressed into soft clay at the bottom of a bore hole. Torque was applied and gradually increased 45 N-m when failure took place. Subsequently the vane rotated rapidly so as to completely remould the soil..
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
Two aluminium bars (E = 70 GPa) are attached to regid support at the left and a cross-bar at the end. An iron bar (E = 200 GPa) is at attached to the rigid support at the left and there is a gap b = 0.6 mm between the right end of the iron bar and cr..
