a) What are edge and screw dislocations and why are they
important in metals?;
b-) Make a 2D sketch of an edge dislocation using the ball and
stick model of the crystalline state and show its salient features
such as extra-half plane, dislocation core, state of stress above
and below the slip plane, and Burger’s vector. What does the
Burgers vector designate?;
(c-) Why does dislocation slip take place on closed packed
crystallographic planes and along close packed crystallographic
directions?...
The drawing shows an edge-on view of two planar surfaces that
intersect and are mutually perpendicular. Surface 1 has an area of
1.5 m2, while surface 2 has an area of 3.4 m2. The electric field E
in the drawing is uniform and has a magnitude of 190 N/C. It is
directed towards the two perpendicular surfaces, making an angle
35o with the bottom surface. Find the electric flux through (a)
surface 1 and (b) surface 2.
For each of the examples below, draw (or
describe drawing) a sampling distribution around the reported mean,
mark the upper and lower limits of the 95% confidence interval, and
compute the mean values that correspond to those upper and lower
limits.
Dr. Grimm collected a random sample of 30 sociology majors and
administered an IQ test (σ = 15). This group had an
average IQ of M = 105. Compute a 95% confidence interval
to determine the population mean of...
How (by what way) is each detail drawing connected with the
assembly drawing of the design? (keep your answer brief and
concise, all lower cases)

For example the company has 10 edge sites (two in each
continent). The edge sites are europe-east, europe-west, asia-east,
asia-west, africa-north, africa-south, americas-north,
americas-south, australia-east and australia-west. Each edge site
has 10 servers serving web content. The servers are named server1 -
server10. Every hour on the hour, you want to bring HTTP web access
logs files in to centralized Hadoop Distributed File System located
in Chicago data center. How would you organize the directory
structure in HDFS under /data/web/access-logs....
An inspector has the job of checking a screw-making machine at
the start of each day. She finds that the machine needs repairs
pairs one day out of ten. When the machine does need repairs, all
the screws it makes are defective. Even when the machine is working
properly, 5% of the screws it makes are defective; these defective
screws are randomly scattered through the day's output. Use a
calculator to get approximate answers to the following lowing
questions. What...
(a) Bulk deformation processes include rolling, forging,
extrusion and drawing. Describe each process. (b) What
is the main difference between hot working and cold working? List
at least two advantages and two disadvantages of cold working. (c)
What is the neutral axis and what is springback in bending
process?
Describe the “screw home mechanism” and name one muscle and one
joint critical to normal functioning of the screw home mechanism.
Explain two treatment techniques that you could use to restore a
malfunctioning “screw home mechanism.”
Describe how you would differentiate between the gluteus medius,
gluteus maximus and tensor fascia lata muscles when testing the
strength of these muscles. Describe what you might observe in an
individual with grade 2+ gluteus medius weakness on their right
side, while standing on...
