Automated payroll system with GPS tracking and image capture
The local municipality department has been struggling to keep up with the maintenance of water pipes and this issue in turn affects the water supply to the community. The department has seen a trend of repeated calls logged of the same faulty pipes that were claimed to have been repaired previously in the same month. On the other hand, the finance department has raised an issue of a high volume of overtime claim maintenance of these water pipes. Management has decided to deal with these issues by developing an application for water pipe fault maintenance and resolution. The fault resolution component will track the time it took a technician to resolve the water pipe and allow them to upload the site pictures (before and after). This automated payroll system doubles up as a web and Android application – while the technician will use the Android interface, the admin (usually the HR) will use the web interface. When an employee logs into the system from an Android device and their image is captured, then the system sends the technician’s image and their GPS location to the Admin.
If the technician stays logged into the application via an Android device, the GPS location will continue to be automatically updated and forwarded to the admin every five minutes. When the technician logs out, their image and GPS location are again sent to the Admin. This application allows Admins to keep track of employee attendance and payroll. The admin creates employee profiles for each employee by entering all the relevant personal information (name, job position, qualification, etc.). They can also check the salary details and breakdown of the salary of each employee by entering the employee ID and date.
Since the application is GPS-enabled, no employee can add proxy attendance. Admin can view latitude and longitude of the GPS location sent by the employee. When the HR login to the system he can check the GPS location of the employee by entering employee ID and date. This enables the HR to keep an accurate record of working days including overtime worked of individual employees and tweak their payroll accordingly.

Answer:

The shear stress will be 80 MPa

Explanation:

Here we have;

τ = (T·r)/J

For rectangular tube, we have;

Average shear stress given as follows;

Where;

\(\tau_{ave} = \frac{T}{2tA_{m}}\)

\(A_m\) = 100 mm × 200 mm = 20000 mm² = 0.02 m²

t = Thickness of the shaft in question = 2 mm = 0.002 m

T = Applied torque

Therefore, 50 MPa = T/(2×0.002×0.02)

T = 50 MPa × 0.00008 m³ = 4000 N·m

Where the dimension is 50 mm × 250 mm, which is 0.05 m × 0.25 m

Therefore, \(A_m\) = 0.05 m × 0.25 m = 0.0125 m².

Therefore, from the following average shear stress formula, we have;

\(\tau_{ave} = \frac{T}{2tA_{m}}\)

Plugging in then values, gives;

\(\tau_{ave} = \frac{4000}{2\times 0.002 \times 0.0125} = 80,000,000 Pa\)

The shear stress will be 80,000,000 Pa or 80 MPa.

The minimum temperature required at the turbine inlet is approximately X degrees Celsius, ensuring the steam leaving the turbine maintains a quality of at least 80%. The thermal efficiency of the cycle, when operated at this temperature, is approximately Y%.

To determine the minimum temperature at the turbine inlet, we need to consider the steam conditions at the turbine exit. Given that the steam quality should be at least 80%, we know that 80% of the mass flow rate will be in the vapor phase, and 20% will be in the liquid phase.

The saturation pressure at the condenser operating pressure of 5 psia can be found using steam tables. Once we have the saturation pressure, we can determine the corresponding temperature.

By applying the first law of thermodynamics, we find the work output of the turbine. From the turbine work and the enthalpy of the steam at the turbine exit, we can determine the enthalpy at the turbine inlet using the steam tables.

Finally, using the enthalpy at the turbine inlet, along with the given boiler pressure of 2500 psia, we can determine the corresponding temperature at the boiler inlet.

The thermal efficiency of the Rankine cycle is the net work output divided by the heat input. The heat input can be calculated using the enthalpy difference between the boiler inlet and condenser exit, considering the mass flow rate and the specific heat of water.

The engineer chooses nanostructured aerogel with a low thermal conductivity to create an effective thermal protection barrier that can insulate the sensitive electronic device from the irradiation of the high-powered infrared laser.

The young engineer has been tasked with designing a thermal protection barrier for a sensitive electronic device that may be exposed to irradiation from a high-powered infrared laser.

The engineer has learned that materials with low thermal conductivity provide good insulation.

In this case, the engineer specifies the use of a nanostructured aerogel with a thermal conductivity of "ka".
Nanostructured aerogel is an excellent choice for thermal insulation due to its low thermal conductivity.

This means that it can effectively reduce the transfer of heat from the laser irradiation to the sensitive electronic device. The "ka" value represents the specific thermal conductivity of the aerogel, which indicates how well it can resist the flow of heat.

The lower the "ka" value, the better the insulation properties of the aerogel.
By using nanostructured aerogel as the thermal protection barrier, the engineer ensures that the sensitive electronic device is shielded from the potentially damaging effects of the laser's irradiation.

This helps to maintain the device's performance and integrity, preventing any potential overheating or malfunction.
In summary, the engineer chooses nanostructured aerogel with a low thermal conductivity to create an effective thermal protection barrier that can insulate the sensitive electronic device from the irradiation of the high-powered infrared laser.

Section Key Terms

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.

The outer diameter of the ball is 6.2138 cm

Explanation:

The formula to apply is ;

Heat loss ,

\(Q/t=kA*\frac{( T_1-T_2)}{d}\)

where ;

Q/t=total heat loss from the ball = 1600 w

k=coefficient of heat transmission through the ball= 2.75 W/m.˚C

A=area in m² of the ball with the coefficient of heat transmission

T₁=Hot temperature

T₂=Cold temperatures

d=thickness of the ball

Area of spherical ball using internal diameter, 3cm= 0.03 m will be

Radius = half the diameter = 0.03/2 = 0.015

Area = 4 *π*r²

Area = 4*π*0.015² = 0.002827 m²

Apply the formula for heat loss to get the thickness as:

1600 = {2.75 * 0.002827 *(250-30 ) }/d

1600 =1.711/d

1600d = 1.711

d=1.711/1600 = 0.001069 m

d= 0.1069

Using internal radius and the thickness to get outer radius as;

3 + 0.1069 = 3.1069 cm

Outer diameter will be twice the outer radius

2*3.1069 = 6.2138 cm
