A CNC milling machine has a purchase price of £120,000 and it is considered from an accounting standpoint to be depreciated to zero value over a period of 5 years. If the machine is to be used for 2 shifts with each shift working for 37 hours/ week and 45 weeks/ year. What is the machine cost/ hr which must be charged in order to amortise/repay the costs over the 5 year period?
To make the calculation simpler, you can assume that over the 5 year period you will be required to pay back 8% interest on the sum borrowed.

John has been hired to design an exciting carnival ride. Tiff, the carnival owner, has decided to create the world's greatest Ferris wheel. Tiff isn't into math; she simply has a vision and has told John these constraints on her dream: (i) the wheel should rotate counterclockwise with an angular speed of a = 13 RPM; (ii) the linear speed of a rider should be 200 mph; (iii) the lowest point on the ride should be c = 4 feet above the level ground. The wheel starts turning when Tiff is at the location P, which makes an angle ? with the horizontal, as pictured. It takes her 1.5 seconds to reach the top of the ride.
Tiff becomes a human missile after 6 seconds on the ride. Her coordinates in that instant are (33.707, 212.818).
Find the equation of the tangential line along which Tiff travels the instant she becomes a human missile. (Round values to three decimal places as needed.)

A company uses various machines in the preparation of ice cream. The firm has been successful until recently when it noticed growing repair expenses for the various machines it uses. Over the past 20 months, the machines have broken down at the rate indicated in the following table:
Each time a machine breaksdown, the company estimates that it loses an average of US$300 in production time and service expenses. Should the company opt to purchase a service contract for preventive maintenance by Angeles Machineries Inc., (AMI) there will still be breakdowns, averaging one breakdown per month. The price for this service by AMI is US$150 per month.
a. If the company continues as is, what is the expected no. of breakdowns based on past history?
b. What will be the cost of breakdowns per month to the company without a preventive maintenance contract?
c. What will be the cost of breakdowns per month to the company with a preventive maintenance contract?

A Company produces mechanical probe to
update OWSVS (Offensive-Warfare-Support-
Vehicle- Systems). For the process of making a
mechanical probe, 10 process steps are
needed. It is calculated that the scrap rate
and rework rate are 12% and 9%, respectively.
The average setup time, average machining
(operational) time and the average non-
operational time can be expressed as: 2.4
hours, 9.6 minutes, and 9.6 hours,
respectively.
a) With a batch size of 520 mechanical
probes, what must be Manufacturing Lead

b) With 8 hours per shift and two shifts per
day, if the plant works 5 days a week, what is
the MLT in weeks?

2) Orthogonal Cutting: Consider a person who is shoveling snow from the sidewalk. This person can
choose between two different shovel designs. Shovel A rides at a 5°angle off the normal to the
sidewalk, while shovel B is oriented at a 30° angle (from the normal to the sidewalk). Either way, two
inches of snow will be removed.
Which shovel will require less pushing force? Please write your answer as the ratio of the force for
shovel A to the force for shovel B. Assume the friction between the snow and the shovel is 1.0. Both
shovels are the same width (into the page). The thickness of the removed snow riding up the face of
the shovel is as shown in the figures. In both cases, the snow has the same physical properties
(strength, stiffness, etc.).

One year ago a machine was purchased at a cost of $2,000, to be useful for 6
years. However, the machine has failed to perform properly and has a costs of
$500 per year per year for repairs, adjustments, and shutdowns. A new machine is
available to accomplish the functions desired and has an initial cost of $3,500. Its
maintenance costs are expected to be $50 per year during its service life of 5
years. The approximate market value of the present machine has been roughly
$1,200. If the operating costs (other than maintenance) for both machines are
equal, show whether it is economical to purchase the new machine. Perform a
before-tax study using an interest rate of 12%, and assume that the salvage values
