x=1/2(u^2-v^2)
y=uv
z=z
A simple curve has a central angle of 42 degreess. A point Y is located 24m from the vertex and has a perpendicular distance of 3.00m from the back tangent.
What are some of the properties that make aluminum an extremely useful engineering material?
The concrete post (Ec=3.6*10^6 psi and Ac= 5.5*10^-6/degrees F) is reinforced with six steel bars. each of 7/8-in diameter (Es=29*10^6 psi and As=6.5*10-6/ degrees F).
If a cylinder of A-36 steel 1 foot long with a diameter of 1 inch is wedged tightly between two immovable isothermal walls and the cylinder is heated from RTt to 300 c what will happen?describe, do not use an equation
A 12kw (shaft output) motor is available to run a non-cooled compresor for helium. The pressure is to be increaded from 80 kPa to 120 kPa. If the compressor is 70% efficent, calculate the volume flow rate into the compressor.
A compressor pressurizes air from 1 atm to 2.38 atm at steady state. At the entry the air's temperature is 70F, whereas at the exit it has quadrupled (in degrees F). At the entry the air's volumetric flow rate is 17 ft3/s
Station 3 + 54.67 must be marked in the field. if the steel tape to be used is only 99.98 under standard conditions and if the temperature is 87 degree farenheit at the time of the measurement, how far away from the existing station mark at 0 + 79.23..
For an intermediate beam in 3 bays by 3 bays (each bay is 20' by 20') floor plan, draw the envelope shear and moment diagrams taking into account effect of pattern loading.
The concentration of ammonia is 6 mg/L at one point in the river. If the first – order decay coefficient for the conversion of ammonia to nitrate is 0.05 day-1, what will the ammonia concentration be 10 miles downstream.
The company will use an annual interest rate of 10%. Annual maintenance and pumping costs may be considered to be paid in their entireties at the end of the years in which their costs are incurred.
A sky diver with a mass of 75 kg jumps from an aircraft. The aerodynamic drag force acting on the sky diver is known to be Fd = kV^2, where k = 0.228. Determine the maximum speed of the free fall for the sky diver and the speed reached after 100 m..
