Answer:

The thickness of the walls of each hollow lump of "iron ore" is 2.2 cm

Explanation:

Here we have that the density of solid gold = 19.3 g/cm³

Density of real iron ore = 5.15 g/cm³

Diameter of sphere of gold = 4 cm

Therefore, volume of sphere = 4/3·π·r³ = 4/3×π×2³ = 33.5 cm³

Mass of equivalent iron = Density of iron × Volume of iron = 5.15 × 33.5

Mass of equivalent iron = 172.6 cm³

∴ Mass of gold per lump = Mass of equivalent iron = 172.6 cm³

Volume of gold per lump = Mass of gold per lump/(Density of the gold)

Volume of gold per lump = 172.6/19.3 = 8.94 cm³

Since the gold is formed into hollow spheres, we have;

Let the radius of the hollow sphere = a

Therefore;

Total volume of the hollow gold sphere = Volume of gold per lump - void sphere of radius, a

Therefore;

\(33.5 = 8.94 - \frac{4}{3} \times \pi \times a^3\)

\(\frac{4}{3} \times \pi \times a^3 = 33.5 - 8.94\)

\(a^3 = \frac{24.6}{\frac{3}{4} \pi } = 5.9\)

a = ∛5.9 = 1.8

The thickness of the walls of each hollow lump of "iron ore" = r - a = 4 - 1.8 = 2.2 cm.

Determining the amount of aluminum required to achieve a specific dislocation length is not possible without more information on crystal structure and material dimensions.

The amount of aluminum required to achieve a specific dislocation length cannot be determined based on the information provided. The dislocation density of 10^12 m/m^3 only provides information on the concentration of dislocations in the material, but it does not give any information on the actual length of the dislocations. Additionally, the comparison to the distance between New York City and Oklahoma is not relevant in this context, as dislocations are three-dimensional structures within the material and not a two-dimensional line. To determine the total dislocation length, one would need to know the crystal structure and dimensions of the material in question.

Answer:

A hammer and a wrench

Explanation:

In Stokes flow, the fluid velocity is proportional to the forces acting on the fluid and the fluid is assumed to be viscous and incompressible. The fluid velocity near a rotating sphere in Stokes flow can be determined using the equations of fluid dynamics.

Kinematic reversibility is a property of Stokes flow, which states that the fluid flow is symmetric with respect to time reversal. This means that if the fluid velocity is recorded at a certain time, then the same velocity field will be obtained if time is reversed and the flow is replayed in the reverse direction.

When a sphere is rotating near a wall, the flow of fluid around the sphere creates a velocity field that pushes the sphere away from the wall. This flow can be considered as the fluid being pushed away from the sphere and towards the wall. If the flow is time-reversed, the fluid velocity field would be the same, but the direction of the velocity would be reversed. This means that the fluid would be drawn towards the sphere and away from the wall, pulling the sphere towards the wall.

Therefore, based on the property of kinematic reversibility in Stokes flow, the rotating sphere near a wall will experience a force that could either push it away from the wall or draw it towards the wall, depending on the direction of the flow.

Explanation:

Given the data in the question;

A₁ = 9-inch × 9-inch = 81 in² = 81 / 144 = 0.5625 ft²

V₁ = 6.1 ft/s

A₂ = 13 in × 13 in = 169 in² = 1.17361 ft²

v₂ = ?

using the the equation if continuity

( Rate of volumetric flow is constant )

A₁V₁ = A₂V₂

we substitute

0.5625 ft² × 6.1 ft/s = 1.17361 ft² × V₂

3.43125 ft³/s = 1.17361 ft² × V₂  

V₂  = 3.43125 ft³/s  / 1.17361 ft²

V₂ = 2.9237 ft/s

Therefore, the speed of the air flowing into the room is 2.9237 ft/s

One example of an OSHA-required sharp with engineered injury protection is a safety scalpel. Safety scalpels are specifically designed to reduce the risk of accidental cuts and injuries during medical procedures or other tasks that require the use of a scalpel.

The safety scalpel incorporates various features to enhance user safety, including:

1. Retractable Blade: Safety scalpels often have a retractable blade mechanism. The blade can be extended for use, but it automatically retracts into the handle or sheath once pressure is released or when the cutting action is complete. This feature helps prevent accidental cuts or injuries when the scalpel is not in use.

2. Shield or Guard: Many safety scalpels come with a shield or guard that covers the blade when it is not in use. The shield acts as a physical barrier, preventing accidental contact with the blade and reducing the risk of injuries.

3. Activation Mechanism: Safety scalpels typically feature an activation mechanism that requires a deliberate action or a specific grip to engage the blade. This helps ensure that the blade is only exposed when intended, minimizing the potential for unintentional cuts.

4. One-Time Use: Some safety scalpels are designed for single-use, meaning that they are disposed of after a single procedure. This eliminates the need for blade handling, retraction, or disposal, further reducing the risk of injuries associated with blade manipulation.

These engineered injury protection features in safety scalpels are in line with OSHA's guidelines to minimize the risk of sharps injuries in healthcare settings and other industries where sharp objects are used. By implementing these safety measures, safety scalpels help protect healthcare workers, patients, and others from accidental cuts, thereby promoting a safer working environment.

The reason for their unusual properties of the greasy feel and low hardness is that the chemical bonds between the sheets is so weak that very low stresses can allow slip between the sheets.

Explanation:

Talc is a monoclinic mineral with a sheet structure similar to the micas and also has perfect cleavage that follows planes between the weakly bonded sheets.

Now, these sheets are held together only by van der Waals bonds and this allows them to slip past each other easily. Thus, this unique characteristic is responsible for talc's extreme softness, its greasy, soapy feel, and its value as a high-temperature lubricant.

While for graphite, it's carbon atoms are linked in a hexagonal network which forms sheets that are one atom thick. It's sheets are poorly connected and easily cleave or slide over one another when subjected to a small amount of force. Thus, gives graphite its very low hardness, its perfect cleavage, and its slippery feel.

So, we can conclude that the reason for their unusual properties is that the chemical bonds between the sheets is so weak that very low stresses can allow slip between the sheets; hence, the greasy feel and low hardness.

The use of inches of water column as a unit of measurement for gas pressure is mainly due to the fact that gas pressures must be accurately set for correct operation.

Unlike psig (pounds per square inch gauge), which measures pressure relative to atmospheric pressure, inches of water column measures the pressure differential between two points, making it a more precise measurement for low-pressure systems.Furthermore, gas manifold pressures are often too small for accurate measurement in psig, which is typically used for higher-pressure systems. Inches of water column is a more suitable unit for measuring the small pressure differentials found in gas manifold systems.In summary, the use of inches of water column as a measurement for gas pressure is a more precise and suitable option for accurately setting gas pressures in low-pressure systems, where psig may not be a practical unit of measurement.The reason "inches of water column" is used to measure gas pressure instead of psig is because of the following factors:
A) Gas pressures must be accurately set for correct operation: Ensuring the correct pressure for gas systems is essential for safety and efficiency.
C) Gas manifold pressures are too small for accurate measurement in PSI: Inches of water column provides a more sensitive and precise measurement for low gas pressures typically found in these applications.
D) It is a more precise measurement: Using inches of water column allows for more accurate and consistent pressure readings, which is vital for proper functioning and safety in gas systems.

Answer:

There are three common methods of charging a battery; constant voltage, constant current and a combination of constant voltage/constant current with or without a smart charging circuit.

Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage.  The current will then taper down to a minimum value once that voltage level is reached.  The battery can be left connected to the charger until ready for use and will remain at that “float voltage”, trickle charging to compensate for normal battery self-discharge.

Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating.  Charge times are relatively long with the disadvantage that the battery may overheat if it is over-charged, leading to premature battery replacement.  This method is suitable for Ni-MH type of batteries.  The battery must be disconnected, or a timer function used once charged.

Constant voltage / constant current (CVCC) is a combination of the above two methods.  The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level.  The current then reduces as the battery becomes fully charged.  The lead acid battery uses the constant current constant voltage (CC/CV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation.

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

We can calculate the real and reactive power supplied to the motor from the input current and power factor, the output power from the efficiency and input power,

(a) The total real power supplied to the motor is

240 V x 15 A x 0.8 pf = 2.88 kW

and the reactive power supplied to the motor is

240 V x 15 A x sin(arccos(0.8)) = 2.135 kVAR.

(b) The output power of the motor is the input power multiplied by the efficiency, so it is

2.88 kW x 0.95 = 2.736 kW.

(c) The balanced, parallel, delta-connected impedance that allows the motor to draw the same current at unity pf is equal to the impedance of the motor at its operating point divided by the power factor at the operating point. This can be calculated using the formula

\(Z = V^2 / (S * pf)\) , where Z is the impedance, V is the voltage, S is the apparent power, and pf is the power factor.

Solving for Z, we get

\(Z = 240^2 / (15 *0.8) = 2304ohm\)

Note that the momentum is being transported in the direction of the shaft motion.

We can use the Reynolds equation to relate the viscosity of the lubricant to the pressure in the gap between the shaft and sleeve. The Reynolds equation for a slider bearing is given by:

∂(h^3p)/∂x = -12μV

where h is the gap thickness, p is the pressure, x is the axial direction, μ is the viscosity of the lubricant, and V is the velocity of the shaft.

To limit the total force on the sleeve to less than 2.2 N, we can calculate the maximum pressure as:

P = F/A = 2.2 N / (π(2.6/2)^2) = 0.06 MPa

At a velocity of 6.1 m/s, the flux of momentum in the gap is given by:

Φ = h^3p / 12μ

We can rearrange the Reynolds equation to solve for the viscosity:

μ = h^3p / (-12V(∂p/∂x))

Since the sleeve is free to move axially, we can assume that there is no pressure gradient in the axial direction (∂p/∂x = 0). Therefore, the viscosity can be calculated as:

μ = h^3p / (-12V(∂p/∂x)) = h^3p / (-12V(0)) = 0

This means that the viscosity of the grease can be zero, and the pressure in the gap can still be limited to 0.06 MPa to keep the total force on the sleeve below 2.2 N.

The magnitude of the flux of momentum in the gap is given by:

Φ = h^3p / 12μ = (5.08/100)^3 * 0.06 MPa / (12 * 0 Pa s) = 1.56 x 10^-9 kg m/s
