(a) Define the hardenability of a steel. (b) Define the hardness of a steel. (c) Describe the Jominy hardenability test. (d) Explain how the data for the plotting of the Jominy curve are obtained and how the curve is constructed.
Member ABC is composed of two sections. Section AB has an outside diameter of 60mm and inside diameter of 50mm, whereas section BC is solid. Find the maximum shear stress due to the 1.5kN·m torsional moment applied at B and the 2.0kN·m moment at C..
The 75 lb block is released from rest 5 ft above the plate. Determine the compression of each spring when the block momentarily comes to rest after striking the plate.
The potentiometric surface elevations at two observation wells 1000 m apart are 52.35 m and 56.90 m. If the horizontal hydraulic conductivity of the auquifer is 25 m/ day determine the flow rate per unit width of the auquifer.
A more conservative increase from 27.5 mpg in 2011 to 35 mpg by 2020 is supported widely in Washington. California and 13 other states + the District of Columbia hope to increase that stander to 35 mpg by 2017 and 40 mpg by 2020.
A rectangular open channel with a width of 10 ft and n = 0.013 conveys a discharge of 300 cfs. The upstream portion of the channel has a slope of 10%, which then abruptly changes to a slope of zero downstream.
calculate the chord lenght between stations 75.00 and 75.00 on a circular curve with Da=5.5 degrees.
Assume the rate constant for BOD decay is 0.2 d^-1, the mean velocity of the stream is 0.5 m s^-1, and the initial concentration is 100 mg L^-1 at x=0. Plot the resulting concentration with downstream distance x in km.
Determine the air pressure at the top of a 300 m high building by assuming the density of air stays constant at the z = 0 value. Now compute the pressure assuming the density of the air varies. Is there a significant difference.
Use input values of epsilon (B1), pipe radius (B2), and Reynolds number (B3) to estimate "f" and place these in the same cells . Display the final answer in a message box and round to five figures. Use a short cut key of Ctrl+g
it has been calculated that the maximum density for the soil will be obtained when the water content reaches 21.5%. Compute how many grams of water must be added to each 1000g of soil( in its natural state) in order to increase the water content 2..
The first stratum is confined, and the second one is unconfined, and the water surface elevations in the channels are 24 m and 16 m above the bottom of the unconfined aquifer.
