MACHINE SHOP CALCULATION - OD1640 - LESSON 1/PE 1
PRACTICAL EXERCISE 1
1.
Instructions
Read the scenario and respond to the requirements that follow the scenario.
2.
Scenario
You are the Repair Shop Technician in charge of the service section of a
heavy maintenance company stationed in Texas. The shop officer has notified
you that the maneuver elements of the division will participate in a field
exercise scheduled to take place in 60 days.
The maintenance company has
been tasked to start mechanically preparing the maneuver element's equipment
for this exercise. As a result of this tasking, the machine shop will have
to fabricate a large number of repair parts and devices not found in the
supply system, and still support the normal everyday mission requirements.
The machine shop currently has its full authorization of two machinists.
The new requirement, however, imposes an additional workload that cannot be
completed in the allotted amount of time without additional machinists.
There are two welders in your service section that are former machinists.
Since the welding shop is currently not overloaded you decide to establish a
second workshift by using these two welders as machinists to assist in
completing the additional workload. However, you need to know the extent of
their knowledge of machine shop calculations. You may have to provide them
with refresher training.
You have, therefore, developed a list of
mathematical problems that will assist you in determining the extent of
their knowledge of machine shop calculations.
3.
Requirement
Below is the list of mathematical problems you developed.
Prepare the
answer sheet by solving these problems.
a.
Which is the larger fraction 7/9 or 9/7?
b.
Reduce 560/630 to its lowest terms.
