A V-8 engine that posses a firing order of 18436572 with number 1 cylinder on compression, the cylinder which would be on the exhaust stroke is number: A. 6.

An injector can be defined as a mechanical device that is designed and developed for the introduction of fuel into the internal combustion system of an engine, especially under pressure.

In Engineering, there are two (2) main types of fuel injection system and these include the following:

A sequential fuel injection is typically designed and developed to spray fuel into the internal combustion system of an engine based on the firing order that is configured within it by the manufacturer.

As a general rule, one of the two-paired spark plugs within the internal combustion system of an engine is always designed to have a negative polarity while the other spark plug is designed to have a positive polarity always.

In this context, we can infer and logically deduce that a V-8 engine that posses a firing order of 18436572 with number 1 cylinder on compression, the cylinder which would be on the exhaust stroke is number 6.

Explanation:

Answer:

the process capability index for the precision machining process is 0.667

Explanation:

Given the data in the question;

Lower Specification Limits LSL = 0.99 mm

Upper Specification Limits USL = 1.01 mm.

The standard deviation σ = 0.005 mm

mean μ = 1 mm

capability index Cpk = ?

Cpk = min( USL - μ / 3σ, μ - LSL / 3σ )

we substitute

Cpk = min( 1.01 mm - 1 mm / 3(0.005 mm ), 1 - 0.99 mm / 3(0.005 mm) )

Cpk = min( 0.01 mm / 0.015 mm, 0.01 mm / 0.015 mm )

Cpk = min( 0.6666, 0.6666 )

∴ Cpk = 0.6666 ≈ 0.667

Therefore, the process capability index for the precision machining process is 0.667

Here options 1, 2, 3, and 4 would all make you use a brushless DC motor instead of a brushed DC motor.

There are several reasons why one might use a brushless DC motor instead of a brushed DC motor. Firstly, if you have no way to change the brushes, a brushless DC motor would be a better option as it eliminates the need for brushes altogether. Secondly, if you must control the motor rotation angle in discrete steps, a brushless DC motor is more suitable as it allows for precise control of the rotor position. Additionally, if you need a DC servomotor or if you must control the position and velocity of the motor extremely accurately, a brushless DC motor is the better choice as it offers higher accuracy and precision compared to a brushed DC motor.

Alloys are typically stronger than pure metals because impurity atoms within the metal's crystal structure impose lattice strains on the surrounding atoms which ultimately reduce the mobility of dislocations.

The presence of impurity atoms in an alloy can disrupt the regular arrangement of atoms in the crystal lattice of a pure metal. These disruptions, known as lattice strains or lattice distortions, can hinder the movement of dislocations, which are lines or planes of defects in the crystal lattice that allow for plastic deformation (permanent deformation) of metals. By reducing the mobility of dislocations, the lattice strains introduced by impurity atoms can make it more difficult for the metal to deform, resulting in increased strength and hardness. Additionally, alloying can also lead to the formation of solid solution phases, which are homogenous mixtures of two or more metals at the atomic level. Solid solution strengthening can further contribute to the increased strength of alloys by impeding the movement of dislocations and enhancing the overall mechanical properties of the material.

360 degrees of crankshaft rotation for a piston to move from tdc to bdc and return to tdc.

The crankshaft must rotate fully twice (or 720 degrees) in a four-stroke cycle to complete an engine cycle, spinning 360 degrees each time the piston moves from TDC to BDC and back. The engine completes this reciprocation about 125 times per second in a car with a redline of roughly 7500 rpm.

A timing belt or chain is used to connect key engine components together and maintain everything in synchronization in order to hold this incredibly precise sequence of actions together. A thick, toothed belt called a timing belt wraps around the crankshaft, water pump, and camshaft sprockets, spinning in time with the crankshaft at the base of the engine block.

The output at sample index n = -3 using convolution formula is y[-3] = 4.

Given:

x[n] = u[n]

h[n] = a u[-n-1]

where a = 4.

The convolution formula is:

y[n] = ∑[k = -∞ to ∞] (x[k] h[n - k])

In this case, we have:

y[n] = ∑[k = -∞ to ∞] (u[k] (4 u[-(n - k) - 1]))

To calculate y[-3], we substitute n = -3:

y[-3] = ∑[k = -∞ to ∞] (u[k]  (4 u[-(-3 - k) - 1]))

y[-3] = ∑[k = -∞ to ∞] (u[k] (4  u[-2 - k]))

Now , the value of y[-3] by considering the conditions of the unit step function:

For k < 0, u[k] = 0.

For k ≥ 0, u[k] = 1.

Since the sum starts at k = -∞.

For k ≥ 0, u[-2 - k] will be non-zero when -2 - k ≥ 0, which implies k <= -2.

So, the sum simplifies to:

y[-3] = ∑[k = -∞ to -2] (4 * u[-2 - k])

Since u[-2 - k] = 1 for k = -2 and u[-2 - k] = 0 for k < -2,

y[-3] = 4  u[-2 - (-2)] = 4  u[0]

Since u[0] = 1, we have:

y[-3] = 4 x 1 = 4

Therefore, the output at sample index n = -3 is y[-3] = 4.

The magnitude of the small gravitational force of mutual attraction is 1.67 x 10⁻⁷ N.

Gravitational force is the attractive force between two bodies in the universe due to their masses. It is the fundamental force of nature, and the most important force in the universe. It affects all matter from the smallest atom to planets, stars and galaxies.

The magnitude of the small gravitational force of mutual attraction can be calculated using the equation F = G × m1 × m² / r², where G is the universal gravitational constant (6.67 × 10^-11 N*m²/kg²), m1 and m2 are the masses of the two objects, and r is the distance between them. Therefore, the equation becomes F = G × m1² / r².

For this problem, m1 = m2 = 0.001 kg, r = 40 mm = 0.04 m.

Therefore, F = G × m1² / r² = 6.67 x 10⁻¹¹ N × m2/kg² * (0.001 kg)² / (0.04 m)² = 1.67 x 10⁻⁷ N.

Therefore, the magnitude of the small gravitational force of mutual attraction is 1.67 x 10⁻⁷ N.

The force sensor would read low. When there is an angle ϴ between the direction the string pulls and the sensor's measuring direction.

the measured force is the component of the force vector in the sensor's direction. As ϴ increases, the component of the force vector in the sensor's direction decreases, resulting in a lower reading on the force sensor. The force sensor measures the force along its measuring direction, so any deviation from that direction reduces the measured force value. The force sensor would read low.

Approximately 0.0306 grams of silver can be plated onto the cathode.

To calculate the grams of silver plated onto the cathode, we can use Faraday's law of electrolysis. First, we need to convert the time from minutes to seconds:

72 minutes = 72 * 60 = 4320 seconds

Next, we can use the formula:Amount of silver plated (in grams) = (Current * Time) / (Faraday's constant * Number of electrons transferred)

Since one mole of silver ions requires one mole of electrons to plate onto the cathode, the number of electrons transferred is 1.

Plugging in the given values:

Amount of silver plated = (6.8 A * 4320 s) / (9.65 × \(10^4\) C/mol * 1)

Calculating the result:

Amount of silver plated = 0.0306 grams

Explanation:

Determine the daily methane production in liters

For waste cooking oil ;

Delivered amount in liters  = 757.082 liters per week

daily = 757.082 / 7 = 108.154 L/day

waste vs concentration = 25,000 mg/L

Its volatile solid  = 25000 * 10^-3 (g/l) * 108.154 L/day

                           = 2703.864  g/day

hence methane production in liters

= 600 L/g * 2703.864 g/day

= 1622318.57 L

For cow manure

Delivered amount in liters = 500 liters / day

Vs concentration = 5000 mg/l

Hence amount of Vs = 5000 * 10^-3 * 500  = 2500 ( g/day)

methane production in liters

= 150 * 2500 = 375000 liters

For glass clippings

Delivered amount in liters per day  = 1135.62 / 7 = 162.23 L/day

amount of Vs = 15000 * 10^-3 (g/L) * 162.23 L/day = 2438.45 ( g/day )

hence the methane production in liters

= 300 * 2433.45 = 730035 L

Hence ∑ daily methane production of each waste

=  1622318.57 + 375000 + 730035 = 2727000 Liters
