For the tape of Problems 6.8 through 6.11, determine the true horizontal length of the recorded slope distance BC for the conditions shown in Problems (Assume the tape was fully supported for all measurements.)
Problem 6.8:
A 100-ft steel tape of cross-sectional area 0.0025 in.2, weight 2.3 lb, and standardized at 68°F is 99.992 ft between end marks when supported throughout under a 12-lb pull. What is the true horizontal length of a recorded distance AB for the conditions given in Problems (Assume horizontal taping and all full tape lengths except the last.)
Explain why the maximum flow rate per unit area for a given gas depends only on P0/ 0.For an ideal gas with k = 1.4 and R = 0.287 kJ/kg · K, find the constant a such that m . /A* = aP0/0.
A flood control project has a construction cost during the first year of $10 million, during the second year $6 million, and during the third year $2 million. It is completed at the end of the third year and thereafter incurs an annual operating c..
An underground limestone mine with production of 12,000 tons/day will use trucks for the main haulage between an ore pass and a hoist skip pocket. The hauling distance is 5500 ft. The main haulage drift is horizontal and is 12.5 ft wide and 12.5 f..
Aluminum cans in the 1970's were considerably heavier than they arenow. For a 0.355-L (12 oz) aluminum can, with mass 0.0205 kg, andusing a 25 percent recycling rate, find the primary energy requiredto produce the aluminum in one such can.
A short reinforced concrete column 250mm square carries an axial load of 30 Mg. the column is reinforced with 40 mm diameter bars. if the modulus of elasticity for steel is fifteen times that for concrete, find the stresses in the steel and concrete...
Use MATLAB to determine how many days the price of stock A was above both the price of stock B and the price of stock C.
A train which is traveling at 80 mph applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 60 mph as it passes a point 1/2 miles beyonds A.
A weir is to be installed to measure flows in the range of 0.5 to 1.0 m3/sec. If the maximum (total) depth of water that can be accommodated at the weir is 1m and the width of the channel is 4m, determine the crest height of a suppressed weir that sh..

How many hours should it take an articulated wheel loader equipped with a 4 yd3 bucket to load 3,000 yd3 of gravel from a stockpile into rail cars if the average haul distance is 300 feet one way
The cable is taut and prevents motion of point B in the x-z plane (i.e. acts as a pin for y-axis buckling), but offers no restraint to motion in the y-z plane (i.e. is unsupported for x-axis buckling).
