design a horizontal curve for atwo-lane road. The road has 12-ft lanes. Due toexpensive excavation, it is determined that a maximumof 34 ft can be cleared from the road's centerline toward the inside lane to provide for stopping sight distance. Also, local guidelines dictate a maximumsuperelevation of 0.08 ft/ft. What is the highest possibledesign speed for this curve?
One kilogram of air (which behaves as an ideal gas) in a piston-cylinder assembly is subjected to two separate processes from the same initial to the same final state: at the initial state the air has a volume of 1,000 L, a pressure of 10^5 N/m2,
What are the velocities of both just before impact and just after impact. There is a distance of 5m between the vehicles prior to the winch being turned on.
The plate OAB forms an equilateral triangle which rotates counterclockwise with increasing speed about point O. If the normal and tangential components of acceleration of the centroid C
A steel bar is attached to a wood support beam with four 20 mm diameter lag screws. The steel bar is 75-mm-wide by 6-mm-thick. For the steel bar, the yield strength is 260 MPa and the ultimate bearing strength is 350 MPa.
an air space above a long tube is pressurized to 50 kPa vacuum. water (20 degrees C) from a reservoir fills the tube to a height h. If the pressure in the air space is changed to 25kPa vacuum, will h increase or decrease and by how much

Aerotron Electronics is considering purchasing a water filtration system to assist in circuit board manufacturing. The system costs $40,000. It has an expected life of 7 years at which time its salvage value will be $7,500.
Use microsoft excel functions to find the net present worth of the project, and the internal rate of return,and the annual worth of the project?
Calculate the stress at failure of a concrete test cylinder with a measured diameter of 152.4 mm and a recorded load of 371,426N. Units of ksi.
A quality of water within a piston-cylinder assembly executes a Carnot power cycle. During isothermal expansion, the water is heated from saturated liquid at 50 bar until it is a saturated vapor. The vapor then expands adiabatically to a pressure ..
An equal-tangent crest curve connects a +2% initial grade with a -1% final grade, and is designed for 55 mi/h. The station of the PVI is 233 + 40 with elevation 1203 ft.
A compressible 12-ft clay layer beneath a building is overlain by a stratum of sand and gravel and underlain by impermeable bedrock. The total expected primary consolidation settlement of the compressible clay layer due to the building load is 4.6..
