13.
Why is a fuel tank cap fitted with a valve?
A fuel tank cap is fitted with a valve for several important reasons:
Preventing Fuel Spillage: The valve in the fuel tank cap helps prevent fuel from spilling out of the tank, especially during vehicle movement or when the tank is full. It ensures that fuel remains securely contained within the tank, reducing the risk of environmental pollution and fire hazards.
Maintaining Fuel System Pressure: The valve in the fuel tank cap allows the fuel tank to maintain a consistent pressure level. This is important for proper fuel system operation, including fuel delivery to the engine. It prevents the formation of a vacuum inside the tank, which can impede fuel flow and
lead to engine performance issues.
14.
What lines or pipes connect the engine to the fuel tank?
Supply and return pipes
Multiple Choice question. Select the correct answer.
15.
The fuel filter on a modern vehicle is typically mounted.
A.
Under the vehicle
.
B.
On the end of the fuel rail.
C.
On the intake manifold.
D.
On the side of the engine block.
16.
The role of the fuel filter is?
To collect any dirt or contaminants before they get into the fuel system.

What is the purpose of the strainer filter in the tank?
Prevent the large contaminants particles from entering the fuel system that could damage it.
18.
Describe briefly how a mechanical fuel pump function. The lever makes contact with the eccentric on the camshaft which pulls the diaphragm down creating suction which allows the fuel to enter the chamber via one way valve. As the lever returns to its normal position the spring forces The diaphragm up and the fuel exits the chamber via the second one way valve.
19.
What is the function of the diaphragm spring? To create upward pressure on the diaphragm to push the fuel put of the pump.

Question 2
You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture
fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates
implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial
weight bearing activities.
Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to
verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into
solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending
test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the
yield stress for the…

QUESTION 2
A company needs to choose one supplier for a particular type of silicon wafer used'in the production of
semiconductors. The company has three options. Supplier A sells the silicon wafers for $2.50 per wafer,
independently of the number of wafers ordered. Supplier B sells the wafers for $2.40 each but does not
consider an order for less than 2,000 wafers. Supplier C sells the wafers for $2.30 each but does not accept
an order for less than 3,000 wafers. Assume an order setup cost of $100 and an annual requirement of 20,000
wafers. Assume a 20% annual interest rate for holding cost calculations.
a. Which supplier should be chosen to minimize the total annual cost for the wafers, and what is the
optimal order quantity?
b. If the replenishment lead time for wafers…

A Team of Engineers asked for an internal combustion engine to use it in a designed car. Your role is to describe the operation sequence of different types of available engines, explain their mechanical efficiency, and deliver a detailed technical report to show your approach in solving and discussing the following tasks and issues.
You must follow the following steps to help the team:
STEP 1
Describe the operational sequence of four-stroke spark ignition and four-stroke compression ignition engines with the aid of sketches by constructing simple sketch representing the operation and plotting the P-V diagrams for each process during the cycle to show the following:
The input and output heat and net output work
The expansion and compression strokes
The air-fuel mixture intake and exhaust gasses
The spark plug when it is in the active mode
The complete cycle of ideal Otto and Diesel cycles that shows the input and output heat and net output work.
STEP 2
Explain the mechanical…

Four months into a six month deployment, you are a solo pilot returning to home base after an uneventful overwatch mission to a non-disclosed desert
location. Your mission was extended 90 minutes requiring at least one additional aerial refuel. The moon has now set. A shift in prevailing winds causes an
infrequently used runway to be active. You are less familiar with the approach to this runway and have only used it during VFR conditions. The instrument
approach plate reveals you will fly a prolonged DME arc taking you out over the unlit desert away from the dimly lit base.
While flying the above instrument approach, you take another look at the approach plate. When you look up again the airfield lights are visible through the
upper portion of your canopy. You did not sense any change in your aircraft attitude. Which of the following best describes what happened while you looked
at the approach plate?
OA. The black hole effect has amplified the normal reflection of the airfield lights…
