i) A series of cold rolling operations are to be used to reduce the thickness of a metal plate from 50 mm to 20 mm in a reversing two-high mill. Roll diameter is 600 mm, and coefficient of friction between rolls and work is 0.15. The specification is that the draft is to be equal on each pass. Determine:
(a) Minimum number of passes required
(b) Draft for each pass
ii) Suppose that the percent reduction rather than the draft were specified to be equal for each pass.
(a) Determine the minimum number of passes required
(b) Determine the draft and exiting stock thickness for each pass

1. What thickness of concrete and of lead are needed to reduce
the intensity of narrow 500 keV photon beam to one-fourth its
value? Compare the thickness in cm and in g/cm2. Repeat for 1.5 MeV
photons.
2. A 3 MeV point source of grams is located at the center of a
6.0 cm diameter iron sphere. The lead sphere is surrounded by a
spherical shell of lead 3 cm thick (The resulting sphere is a
radius 6.0 cm).

The five key goals of the operations manager are to reduce
costs, reduce variability and improve logistics flows, improve
productivity, improve quality of customer service, and continuously
improve business processes.
Describe from your work and/or personal life how you have
observed someone manage an operation that achieved all or many of
the goals of an operations manager. Give some examples of how some
lacking areas could be improved.

Ultrasound was used to gather the accompanying corrosion data on
the thickness of the floor plate of an above ground tank used to
store crude oil; each observation is the largest pit depth in the
plate, expressed in milli-in: 40, 52, 55, 60, 70, 75, 83, 85, 90,
90.

Heat treating is often used to carburize metal parts, such as
gears. The thickness of the carburized layer is considered a
crucial feature of the gear and contributes to the overall
reliability of the part. Because of the critical nature of this
feature, two different lab tests are performed on each furnace
load. One test is run on a sample pin that accompanies each load.
The other test is a destructive test, where an actual part is
cross-sectioned. This test...
