Vehicles A and B are traveling toward each other in the opposing lanes on a straight segment of a two-lane highway at 35 and 40 mph respectively. If the critical rates of angular change of the two drivers are 0.0065 and 0.0055 rad/s, determine(a) which driver will be the first to displace laterally and(b) the longitudinal distance between vehicles when the displacement will occur. Assume that the lateral separation between the vehicles is 6 ft.
What is work? Why is it path dependant? Derive the expression for reversible work from a closed system containing a simple compressible substance.
Assume you are an observer standing at a point on the track for a period of 30 minutes and are recording the instantaneous speed of each vehicle as it crosses your point. What is the time-mean speed and space-mean speed for these vehicle
Equation for head loss in a pipe when it is laminar flow: head loss, h= (32*dynamic viscosity,u*pipe length,L*average velocity of fluid,V) / (gravitational acceleration,g*pipe diameter,D^2) Give an equation for relative uncertainty of head loss
Determine the diameter of glass tubing that is necessary for the capillary rise to be less than 0.5 mm. Assume the fluid is water with surface tension equal to 0.0728 N/m and specific weight equal to 9800 N/m3
A small house is built in the arctic. It has four square walls of 500 ft2 each. For simplicity, we will assume it has no windows, and we are only interested in calculation the heat loss through the four walls. A total of one hundred Watts (100 kW)..
How do the concepts of green design, industrial ecology, and sustainable developement differ from past approaches to engineering design Prepare a brief report on this topic using some specific examples for illustration.
Labor of this activity is given as in the CREW, 1 brick mason and 1 helper. The productivity is 0.5 labor hours per 1 sf. The wages are for the mason $60 and for the helper $45 per hour.
a) Calculate Darcy's velocity of the groundowater as well as the amount of water that passes through the aquifer each day. b) for the same aquifer, determine the seepage velocity of water through aquifer if the effective porosity is 32%.
What is the specific volume of superheated steam at 42 psia and 340 degrees fahrenheit
a regular hexagonal pyramid has an upper base edge of 16 ft. and a lower base edge of 28 ft. if the volume of the frustum is 18041 ft^3., find the lateral area of the frustum.
calculate the moment of inertia for the Milkyway. Assume it to be a disk.
The first pipe of 400mm diameter is 500 m long, the second pipe 600 m long, size 300mm, and the last pipe is 500m long of diameter 200mm. If the elevation difference between two reservoirs is 30m
