A hole (diameter 5+-0,1 mm) is drilled into a cube (edge 20+- 0,2 mm). Calculate the volume of the body and its cumulative error.
With the technology scaling and process improvement, do you think that existing CMOS (complementary metal-oxide semiconductor) will be able to exist in future?
A piston cylinder contains gas initially at 3500 kPa with a volume of 0.03 cubic meter. The gas is compressed during a process where pV raise to 1.25 = C to a pressure of 8500 kPa. The heat transfer from the gas is 2.5 kJ. Determine the change in internal energy, neglecting changes in kinetic and potential energies. Graph a PV and TS Plane.
Determine the cost of an accident in the workplace from given data.
An untrained employee falls five meters through a fragile roof he was repairing. The worker
had suffered a broken leg and had breathing difficulties. The employee was kept in hospital
for three days. A car parked near the house where the roof was being repaired also suffered
a windscreen damage. An official report found out that ABC LLC company failed to inform
their employee that the roof was fragile nor give him any sort of a training in how to work
safely at height.
The company has been successfully prosecuted under Health and Safety ACT 1974, breach of
duty to employees and lack of training. The company was fined 30,000 Dirhams by the
courts and was widely reported in the press.
From the information given above calculate the approximate cost (both direct and indirect
cost) of the accident. Provide references but also use approximate costs where actual cost is
not available.
An inventor has developed an electronic instrument to monitor the impurities in the metal produced by a smelting process. A company that markets this type of equipment is considering the purchase of the patent rights to this instrument for $40,000. The company feels that there is one chance in 5 of the device becoming a successful seller. It is estimated that if the device is successful, it will produce net revenues of $150,000 a year for the next 5 years. If the product is not a success, no revenue will be received. The company’s interest rate is 15%.

(a) Draw a decision tree describing the decision options and determine the best decision policy
Design a signal conditioning circuit using an NTC thermistor that could measure temperature
within 00C to 300C with ±20C tolerance. The output of this signal conditioning circuit should
be interfaced to an Arduino Uno. The NTC thermistor used for this application is a Standard
Lug NTC manufactured by Vishay. The Ordering number is NTCALUG01A103F [3] [12%]
Explain the consequences of management not abiding by legislation and
regulations and carrying out their roles and responsibilities in a given health and
safety situationز
explain how test procedures produce results
of use to an engineer. Think about what sort of information they will want if they are going
to use the results of the tests to inform the design of a product, e.g. in the case of a
tensile test, the final breaking load is only one of at least five other pieces of data that
can found if the test procedure is correct. Write an explanation (about 500 words) of how
one destructive and one non-destructive test procedure can be carried out so that they
produce results that are useful to an engineer.
Justify the methods used to deal with hazards in accordance with workplace
policies and legal requirements
In this task you need to makereference to the risk assessment outlines in Task5 and the
organisation you visited where you identified hazards and put control measures in place.
You now need to justify the methods used to deal with hazards in accordance with workplace
policies and legal requirement.
