Answer:

Option B: False

Explanation:

A heat engine is a device which operates in a manner that heat is converted into mechanical work.

A simple example of a heat engine is a drinking bird. The oscillatory motion of the drinking bird is as a result of the thermal expansion and contraction of a chemical compound in its beak, which creates an imbalance in its position of equilibrium. This causes it to oscillate.

Heat engines usually work by extracting heat once there is a temperature gradient available in the system and using it to perform work. Another good example is the internal combustion engine. It extracts heat from the explosion of the burning fuels and uses it to power the car.

Tech A and Tech B are incorrect. In Gas Direct Injection engines, fuel is directly injected into the combustion chamber instead of the intake manifold, where the fuel mixes with the air in traditional fuel injection systems.

The Fuel Injectors are mounted directly in the cylinder head or top of the combustion chamber in a GDI engine.In the Gas Direct Injection engines, the air and fuel are mixed only at the time of combustion. During the combustion process, the fuel is sprayed directly into the cylinder head, where it mixes with the air that was compressed during the intake stroke. The fuel-air mixture is ignited by the spark plug and the explosion drives the piston down.

This process is repeated over and over again for each cylinder in the engine.However, if the word 'direct' is removed from Gas Direct Injection Engines, Tech B would be correct. In this scenario, the fuel injectors are mounted on the intake manifold, and the fuel mixes with the air before entering the engine.

(a) The machine's average hourly production rate without considering availability is 6.02 parts/hr.

(b) The machine's average hourly production rate, taking into account availability, is 6.17 parts/hr.

(c) The machine's average hourly production rate when only available during run time is 5.71 parts/hr.

(a) To calculate the average hourly production rate of the machine without considering availability, we need to first calculate the total time it takes to produce a batch of 52 parts.

Total time = (setup time) + (operation time per part x batch size)

Total time = 5.0 hr + (4.2 min/part x 52 parts)/60 min/hr

Total time = 5.0 hr + 3.64 hr

Total time = 8.64 hr

Average hourly production rate = Batch size / Total time

Average hourly production rate = 52 parts / 8.64 hr

Average hourly production rate = 6.02 parts/hr

Therefore, the average hourly production rate of the machine without considering availability is 6.02 parts/hr.

(b) To calculate the average hourly production rate of the machine taking into account availability, we need to first calculate the machine's availability using the mean time between failures (MTBF) and mean time to repair (MTTR) values.

Availability = MTBF / (MTBF + MTTR)

Availability = 37 hr / (37 hr + 0.92 hr)

Availability = 0.975 or 97.5%

Now we can calculate the total time that the machine is available for production:

Available time = Total time x Availability

Available time = 8.64 hr x 0.975

Available time = 8.42 hr

Average hourly production rate = Batch size / Available time

Average hourly production rate = 52 parts / 8.42 hr

Average hourly production rate = 6.17 parts/hr

Therefore, the average hourly production rate of the machine taking into account availability is 6.17 parts/hr.

(c) If availability only applies during the actual run time of the machine and not the setup time, we need to adjust the available time calculation:

Available time = (operation time per part x batch size) / 60 min/hr x Availability

Available time = (4.2 min/part x 52 parts) / 60 min/hr x 0.975

Available time = 4.11 hr

Total time = Available time + setup time

Total time = 4.11 hr + 5.0 hr

Total time = 9.11 hr

Average hourly production rate = Batch size / Total time

Average hourly production rate = 52 parts / 9.11 hr

Average hourly production rate = 5.71 parts/hr

Therefore, the average hourly production rate of the machine taking into account availability only during run time is 5.71 parts/hr.

So the bouy does not float with its axis vertical

Explanation:

From the question we are told that:

Diameter \(d=2m\)

Length \(l=2.5m\)

Weight \(W=22kN\)

Specific weight of sea water \(\mu= 10.25kN/m^3\)

Generally the equation for weight of cylinder is mathematically given by

Weight of cylinder = buoyancy Force

\(W=(pwg)Vd\)

Where

\(V_d=\pi/4(d)^2y\)

Therefore

\(22*10^3=10.25*10^3 *\pi/4(2)^2y\\\\\22*10^3=32201.3247y\\\\\y=1.5m\)

Therefore

Center of Bouyance B

\(B=\frac{y}{2}=0.26m\\\\B=0.75\)

Center of Gravity

\(G=\frac{I.B}{2}=2.6m\)

Generally the equation for\BM is mathematically given by

\(BM=\frac{I}{vd}\\\\BM=\frac{3.142/64*2^4}{3.142/4*2^2*0.5215}\\\\BM=0.479m\\\\\)

Therefore

\(BG=2.6-0.476\\\\BG=0.64m\)

Therefore

\(GM=BM-BG\\\\GM=0.479m-0.64m\\\\GM=-0.161m\\\\\)

Therefore

\(GM<0\)

So the bouy does not float with its axis vertical
