A vertical curve with grade1= 3.6% meets the exit grade of -4.7% at PVI located at station 26.50. A vertical curve of 700 feet is propsed to provide the transition between the two grades. What is the offset at the midpoint on the curve ( elevation difference between PVI and midpoint on the curve). Assume the nearest bench mark is located at station 25.00 with an elevation of 525.00 feet.
A brass alloy has a yield strength of 280 MPa, a tensile strength of 390 MPa, and an elastic modulus of 105 GPa. A cylindrical specimen of this alloy 12.7 mm in diameter and 250 mm long is stressed in tension and found to elongate 7.6 mm.
A 3-in. Schedule 40 steel pipe is 5000 ft long and carries a lubricating oil between two points A and B such that the Reynolds number is 800. Point B is 20 ft higher that A.
An ideal Brayton refrigeration cycle has a compressor ratio of 3.75. The air enters the compressor at 1bar, 27°C. The temperature at the inlet of the turbine is 77°C. Using Air Standard Method Determine on a per unit mass of air flowing
A telephone wire 5 mm in diameter is suspended between telephone poles spaced 50 m apart. If the wind velocity is 100 km/h and the air is at 2 degrees C, 1 atm, determine the horizontal force (in N) the wire exerts on the poles.
A piston-cylinder assembly containing 1/4 kg of a gas undergoes a constant pressure process at 5 bar beginning with a specific volume of 20 m^3/kg. for the gas in the system the work is -15 kj. determine the final volume of the gas in m^3
What is the concentration of tracer in the reactor 1 h after tracer addition is terminated? The reactor had an initial concentration of tracer of 1.0 mg/L when tracer addition commenced.
Two new rides are being compared by a local amusement park in terms of their annual operating costs. The two rides are assumed to be able to generate the same level of revenue (and thus the focus on costs).
(a) Determine the distance d to the point where he lands. (b)What are the magnitudes of his components of velocity parallel and perpendicular to the 45 degree surface just before he lands
Stadia is used to estimate the distance from the instrument to a target. Using inclined sights the horizontal distance and vertical distance between the center of the instrument and the target
