1.The P.C. of a 3 degree curve, whose degree is based on a chord of100 ft. arc, is at Sta. 19+39.60 and the P.T is at Sta. 25+64.60. Calculate the deflection angle from the tangent at the P.C to each100-foot station on the curve and to the P.T.
2.For a meter of soil to form, it requires approximately how many years of exposure to the atmospheric conditions?
3.How do you read the moody chart?
A bucket full of water is to be rotated in the vertical plane. What minimum angular velocity, in rad/s, is necessary to keep the water inside if the rotating arm is 120 cm
Roughly what is the maximum Volume of treated wastewater should you put in the bottle if you want to have at least 2.0mg/l of DO at the test (filling the rest of the bottle with the water
The motor in the unit runs at 300 rpm and produces an unbalanced force of 60 lb at this speed. Neglect weight of the beams and assume 1% viscous deflection in the system; for steel E=30,000 ksi.
The distance from the center of the plate to the point of contact between the plate and the roller is 12 cm. The radius of the roller is 0.5 cm. Assuming no slip between the wheels and the plate, determine the rotational speed of the rollers.
During frequent braking under race conditions the disk brake rotors on the car described above reach a temperature of 500C. These disk brakes rely on forced convection to cool them.
Astructural member in a nuclear reactor is made from a zirconiumalloy. If an axial load of 4 kip is to be supported by the member,determine its required cross-sectional area. Use a factor of safety of 3 with respect to yielding.
payments of $1000 are to be made at the end of each year for the next 3 years. What is the present worth of the three payments if interest is 12% compounded monthly
Determine the % error n in replacing the sine and the tangent of an angle by the value of the angle in radians for angle values 5,10,20 degrees. Explain the qualitative difference between the sine and tangent results.
A 1.5 m diameter culver (concrete barrel, well - rounded entrance) that is 20m long is installed on a slope of 2 percent. The design discharge is 9.5 m^3/sec and the inlet will be submerged but not the outlet.
