Answer:

D) AND gate.

Explanation:

Given that:

A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to la microprocessor acknowledging that it is ready to print

These conditions are:

1. The printer's electronic circuits must be energized.

2. Paper must be loaded and ready to advance.

3. The printer must be "on line" with the microprocessor.

Now; if these conditions are met  the logic gate produces a HIGH output indicating readiness to print.

The objective here is to determine the basic logic gate used in this circuit.

Now;

For NOR gate;

NOR gate gives HIGH only when all the inputs are low. but the question states it that "a HIGH is generated and applied to a 3-input logic gate". This already falsify NOR gate to be the right answer.

For NOT gate.

NOT gate operates with only one input and one output device but here; we are dealing with 3-input logic gate.

Similarly, OR gate gives output as a high if any one of the input signals is high but we need "a HIGH that is generated and applied to a 3-input logic gate".

Finally, AND gate output is HIGH only when all the input signal is HIGH and vice versa, i.e AND gate output is LOW only when all the input signal is LOW. So AND gate satisfies the given criteria that; all the three conditions must be true for the final signal to be HIGH.

The correct statements are (option b) The floated element is taken out of the normal flow, c) The elements after the floated element may overlap with the floated element, and (option d) The floated element no longer takes up the full width of the page.

When we set the float property on an element, it is taken out of the normal flow of the page and moved to the left or right side of its container. This allows other elements to wrap around it. However, this also means that the floated element no longer takes up the full width of the page and may overlap with other elements. The elements after the floated element are not necessarily moved up, but they may wrap around the floated element and overlap with it.

In conclusion, the float property allows an element to be taken out of the normal flow and positioned to the left or right of its container, potentially overlapping with other elements and no longer taking up the full width of the page.

The complete question is;

The wheel and the attached reel have a combined weight of 50 lb and a radius of gyration about their center of ka = 6 in. If pulley B that is attached to the motor is subjected to a torque of M = 50 lb.ft, determine the velocity of the 200lb crate after the pulley has turned 5 revolutions. Neglect the mass of the pulley.

The image of this system is attached.

Answer:

Velocity = 11.8 ft/s

Explanation:

Since the wheel at A rotates about a fixed axis, then;

v_c = ω•r_c

r_c is 4.5 in. Let's convert it to ft.

So, r_c = 4.5/12 ft = 0.375 ft

Thus;

v_c = 0.375ω

Now the mass moment of inertia about of wheel A about it's mass centre is given as;

I_a = m•(k_a)²

The mass in in lb, so let's convert to slug. So, m = 50/32.2 slug = 1.5528 slug

Also, let's convert ka from inches to ft.

So, ka = 6/12 = 0.5

So,I_a = 1.5528 × 0.5²

I_a = 0.388 slug.ft²

The kinetic energy of the system would be;

T = Ta + Tc

Where; Ta = ½•I_a•ω²

And Tc = ½•m_c•(v_c)²

So, T = ½•I_a•ω² + ½•m_c•(v_c)²

Now, m_c is given as 200 lb.

Converting to slug, we have;

m_c = (200/32.2) slugs

Plugging in the relevant values, we have;

T = (½•0.388•ω²) + (½•(200/32.2)•(0.375ω)²)

This now gives;

T = 0.6307 ω²

The system is initially at rest at T1 = 0.

Resolving forces at A, we have; Ax, Ay and Wa. These 3 forces do no work.

Whereas at B, M does positive work and at C, W_c does negative work.

When pulley B rotates, it has an angle of; θ_b = 5 revs × 2π rad/revs = 10π

While the wheel rotates through an angle of;θ_a = (rb/ra) • θ_b

Where, rb = 3 in = 3/12 ft = 0.25 ft

ra = 7.5 in = 7.5/12 ft = 0.625 ft

So, θ_a = (0.25/0.625) × 10π

θ_a = 4π

Thus, we can say that the crate will have am upward displacement through a distance;

s_c = r_c × θ_a = 0.375 × 4π

s_c = 1.5π ft

So, the work done by M is;

U_m = M × θ_b

U_m = 50lb × 10π

U_m = 500π

Also,the work done by W_c is;

U_Wc = -W_c × s_c = -200lb × 1.5π

U_Wc = -300π

From principle of work and energy;

T1 + (U_m + U_Wc) = T

Since T1 is zero as stated earlier,

Thus ;

0 + 500π - 300π = 0.6307 ω²

0.6307ω² = 200π

ω² = 200π/0.6307

ω² = 996.224

ω = √996.224

ω = 31.56 rad/s

We earlier derived that;v_c = 0.375ω

Thus; v_c = 0.375 × 31.56

v_c = 11.8 ft/s

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Rho=76Mpa

Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

Explanation:

To determine if the rings are pure silver, we can calculate the density of the rings and compare it to the density of pure silver. The density of a material is the mass of the material per unit volume.

First, we need to find the volume of one of the rings. Since the rings are cylindrical, we can use the formula for the volume of a cylinder to find the volume of each ring:

V = π * r^2 * h

Where V is the volume of the ring, π is approximately equal to 3.14, r is the radius of the ring, and h is the height of the ring. In this case, the height of the ring is equal to the thickness of the ring, which is equal to the change in the water level (8.45 mm) divided by the number of rings (10). The radius of the ring is equal to half the diameter of the graduated cylinder (2.5 cm / 2 = 1.25 cm), since the rings are placed in the cylinder side by side.

Plugging these values into the formula, we find that the volume of each ring is:

V = 3.14 * (1.25 cm)^2 * (8.45 mm / 10) = 0.00367 cm^3

Next, we can use the mass and volume of each ring to calculate the density of the rings:

density = mass / volume

Since the mass of each ring is 0.738g and the volume of each ring is 0.00367 cm^3, the density of the rings is:

density = 0.738 g / 0.00367 cm^3 = 201.09 g/cm^3

Finally, we can compare the density of the rings to the density of pure silver, which is 10.49 g/cm^3. Since the density of the rings is much higher than the density of pure silver, it is likely that the rings are not pure silver.

It is important to note that this calculation is only an approximate estimation of the purity of the rings. There may be other factors that affect the density of the rings, such as impurities or variations in the thickness of the rings. Additionally, the value of the density of pure silver used in this calculation may not be entirely accurate, as the density of a material can vary depending on factors such as temperature and pressure. A more precise determination of the purity of the rings would require further testing and analysis.

Pumping vast quantities of water locally lowers the local water table.

When large amounts of water are pumped out from underground sources such as wells or aquifers, the water table, which is the level of groundwater, gradually drops. This is because the rate of extraction exceeds the rate of natural replenishment through rainfall or other sources. As a result, the water table decreases, and the surrounding area experiences a lowering of groundwater levels. This can have various effects, including the formation of a cone of depression, where the water table takes on a cone-like shape around the well, and nearby wells or water sources may also be affected by the lowered water table.

Equivalent gradient series = A/P * i(1 + i)n-1

Where, A = SR 3594,

i = 16%,

n = 5 periods,

P = ?

We have to find out P which is a uniform series over periods [1, 5].

Here, first, we will calculate P using equivalent gradient series formula.

Equivalent gradient series = A/P * i(1 + i)n-1

SR 3594 = P/0.16 * (1+0.16)⁵ - 1

SR 3594 * 0.16 = P/0.16 * 0.16 * (1+0.16)⁵ - 0.16P/6.103

= SR 3594P

= SR 3594 * 6.103 ---(1)

Now, we will calculate the sum of the uniform series using the formula;

Sum of the uniform series = (n/2) * (First term + Last term)

Where, n = 5,

First term = P,

Last term = P/5

Sum of the uniform series = (5/2) * (P + P/5)

= 13P/5         --------- (2)

Put value of P from equation (1) in equation (2);

The Sum of the uniform series = 13 * SR 3594 * 6.103/5

= SR 28095.14

Explanation:

steam tables or thermodynamic software and verify the accuracy of the specific enthalpy and internal energy values for water vapor, as well as the properties of air, to ensure precise calculations.

In the given problem, two separate scenarios are described. Let's address each scenario individually.

Scenario 1: Water vapor cooling at constant volume

Starting with water vapor at 2.0 MPa and 300 °C, it is cooled at constant volume until the temperature drops to 150 °C. At the end of the process, we need to find the dryness fraction and the specific internal energy of the saturated liquid-vapor mixture.

To determine the dryness fraction, we need to calculate the quality (x) of the mixture, which represents the mass fraction of vapor present. The dryness fraction can be calculated using the equation:

x = (h - hf) / (hg - hf),

where h is the specific enthalpy of the mixture, hf is the specific enthalpy of the saturated liquid at the final temperature, and hg is the specific enthalpy of the saturated vapor at the final temperature.

The specific internal energy (u) of the saturated liquid-vapor mixture can be determined using the equation:

u = (x * u g) + ((1 - x) * u f),

where ug is the specific internal energy of the saturated vapor at the final temperature, and uf is the specific internal energy of the saturated liquid at the final temperature.

Scenario 2: Compressed air in a cylindrical tank

Given a compressed air pressure of 400 kPa, a tank diameter of 0.3 m, a height of 1.5 m, and the specific gas constant (R) for air as 0.287 kJ/kg·K, we need to find the mass and specific weight of the compressed air.

To determine the mass of the compressed air, we can use the ideal gas law:

PV = mRT,

where P is the pressure, V is the volume of the tank, m is the mass, R is the specific gas constant, and T is the temperature.

The specific weight (γ) can be calculated by dividing the weight (W) of the air by the volume (V) of the tank:

γ = W / V.

By substituting the known values into the equations and performing the necessary calculations, the mass and specific weight of the compressed air can be determined.

Sure! Here's how to draw the shear and moment diagrams for the beam:

To draw the shear diagram, start by finding the shear force at the left end of the beam (V1). This will be equal to M0, since there is no external force acting on the left end of the beam. Then, draw a horizontal line segment to represent the shear force at that point.

Next, move to the right end of the beam (at x=8m). The shear force at this point (V2) will be equal to the shear force at the left end, minus the total load on the beam. So, if the total load on the beam is W, then V2 = M0 - W. Draw a horizontal line segment to represent the shear force at this point.

Finally, connect the two line segments with a smooth curve. This curve represents the variation of the shear force along the length of the beam.

To draw the moment diagram, start by finding the moment at the left end of the beam (M1). This will be equal to 0, since there is no external force acting on the left end of the beam and the shear force is constant (M0) along the length of the beam. Then, draw a horizontal line segment to represent the moment at that point.

Next, move to the right end of the beam (at x=8m). The moment at this point (M2) will be equal to the moment at the left end, plus the total load on the beam multiplied by the length of the beam (WL). So, M2 = M1 + WL = W*L. Draw a horizontal line segment to represent the moment at this point.

Finally, connect the two line segments with a smooth curve. This curve represents the variation of the moment along the length of the beam.

When analyzing transients in DC-powered circuits, an uncharged capacitor is replaced with a short circuit in the initial stages and with an open circuit in the DC steady-state.

When analyzing transient behavior in DC-powered circuits, capacitors are often treated as either short circuits or open circuits depending on the stage of the circuit's operation.

Initially, an uncharged capacitor is treated as a short circuit because it presents low impedance to the incoming DC voltage, allowing current to flow and quickly charge up the capacitor to the source voltage.

As the capacitor charges, its impedance decreases, behaving like a short circuit. However, once the capacitor reaches its maximum charge in the steady-state, it behaves as an open circuit, blocking any further DC current from passing through.

Treating the capacitor as an open circuit in the steady-state simplifies the circuit analysis, as it effectively isolates the DC source from the rest of the circuit.
