In a summation puzzle, you are given three strings of the form POT + PAN = BIB. Typically each is a word, often with a theme to the three chosen. Your goal is to assign a distinct digit to each letter in the equation in order to make the result true. For example, if the puzzle is POT + PAN = BIB, the mapping P:2, O:3, T:1, A:7, N:4, B:5, I:0 will solve this, as 231 + 274 = 505.
Requirements
For this project, you are only required to implement one function found in puzzleSolver.cpp: bool puzzleSolver(const std::string& s1, const std::string& s2, const
std::string& s3, std::unordered_map & mapping)
This function should return true if, and only if, the puzzle is solvable: that is, if there is a mapping of the letters that appear in the three strings to distinct digits such that the sum of the first two is the third (s1 + s2 = s3).
No string will have a value larger than 4,294,967,295 in its correct substitution, nor will the addition have any integer-overflow to check for. If you do not know what integer overflow is, you do not need to check during this assignment (although it’s worth knowing in general).
You may assume it is called with three valid non-empty strings as parameters and with an otherwise empty map. The strings will always consist only of all-capital letters.
The puzzle solution may have a leading zero for a string.
The function takes into account leading zeroes, meaning that a leading zero for a string is a valid solution.
What is function?Function is a named section of a program that performs a specific task. It is a reusable piece of code that can be called from other parts of a program or from other programs.
The purpose of the puzzleSolver() function is to determine whether or not a given set of three strings can be solved as a summation puzzle. The function takes in three strings, s1, s2, and s3, and an unordered_map, mapping. It returns true if the strings can be solved as a summation puzzle, and false otherwise.
To solve the puzzle, the function assigns a unique digit to each letter in the equation. For example, if the puzzle is POT + PAN = BIB, the mapping P:2, O:3, T:1, A:7, N:4, B:5, I:0 will solve this, as 231 + 274 = 505.
The function also assumes that each string will consist only of all-capital letters, and that the resulting solution will not have a value larger than 4,294,967,295. Additionally, the map is assumed to be empty when the function is called.
Finally, the function takes into account leading zeroes, meaning that a leading zero for a string is a valid solution.

A 1.96 in. diameter rod must be machined on a lathe to a smaller diameter for use as a specimen in a tension test. The rod material is expected to break at a normal stress of 68,787 psi. If the tensile testing machine can apply no more than 797 lb of force to the specimen, calculate the maximum rod diameter that should be used for the specimen.
Answer:
Explanation:
The maximum normal stress that can be applied to the specimen is given by the ratio of applied force to the area of the cross section of the specimen:
stress = force / area
The area of the cross section of a rod is given by the formula for the area of a circle:
area = πr^2
where r is the radius of the rod. We are given the diameter of the rod, which is 1.96 inches, so the radius is half of that, or 0.98 inches.
The maximum normal stress that the specimen can withstand is 68,787 psi, and the maximum force that can be applied is 797 lb. Substituting these values into the equation for stress gives:
68,787 psi = 797 lb / πr^2
Solving for the radius r gives:
r = √(797 lb / (68,787 psi × π))
Substituting in the value for π and calculating gives:
r ≈ 0.330 inches
The maximum diameter of the rod is twice the radius, so the maximum diameter is:
d = 2r ≈ 0.660 inches
Therefore, the maximum rod diameter that should be used for the specimen is approximately 0.660 inches.

an equal-tangent sag vertical curve has an initial grade of-2.0%. it is known that the f inal grade is positive and that the low point is at elevation 270 feet and station 141 00. the pvt of the curve is at elevation 275 and the design speed of the curve is 35 mi/hr. determine the station and elevation of the pvc and pvi using the offset method. do not use the y
The Offset Method is a way to determine the station and elevation of the Point of Vertical Curvature (PVC) and the Point of Vertical Intersection (PVI) on an equal-tangent sag vertical curve.
This method involves using the design speed and the elevation of the Point of Vertical Tangent (PVT) to calculate the offset distance, which is then used to find the station and elevation of the PVC and PVI.
Given the initial grade of -2.0%, the final grade being positive, and the low point of the curve being at station 141.00 and elevation 270, we can calculate the offset distance as follows:
Offset Distance = (Design Speed^2) / (386 * Initial Grade)
= (35^2) / (386 * -2.0%) = 612.5 ft
With the offset distance, we can find the station and elevation of the PVC and PVI as follows:
PVC: Station = 141.00 - Offset Distance, Elevation = PVT Elevation + (Offset Distance * Initial Grade)
= 141.00 - 612.5 = 140.375, Elevation = 275 + (612.5 * -2.0%) = 273.125
PVI: Station = 141.00 + Offset Distance, Elevation = PVT Elevation + (Offset Distance * Final Grade)
= 141.00 + 612.5 = 141.625, Elevation = 275 + (612.5 * Final Grade)
Note that the final grade is not known and cannot be calculated using the information provided.
In conclusion, the Offset Method is a useful tool for determining the station and elevation of the PVC and PVI on an equal-tangent sag vertical curve. By using the design speed and elevation of the PVT, the offset distance can be calculated and used to find the PVC and PVI. The accuracy of the results depends on the accuracy of the initial data and the correct application of the method.

Even though the video is shot at 30 frames per second, it may be challenging to find the frame where the "x" is exactly lined up with the equilibrium. Do your best. Did we mention that you need to find the period for trial i?
To determine the period of oscillations in trial i, we need to first identify the equilibrium position, which is the point at which the object is at rest. This is usually a position where the object is in balance and does not move in either direction.
Once the equilibrium position has been identified, we need to measure the time it takes for the object to complete one full cycle of oscillation, from one peak to the next. This time period is referred to as the period of oscillation.
Since the video is shot at 30 frames per second, it may be challenging to find the exact frame where the "x" is exactly lined up with the equilibrium. However, we can make an estimate by observing the motion of the object in the video and using the 30 frames per second as a reference.
It is important to note that the period of oscillation is an important parameter for understanding the behavior of an oscillating system, as it determines the frequency of oscillation. The frequency of oscillation is defined as the number of cycles completed in a given unit of time, typically measured in Hertz (Hz).
In conclusion, to determine the period of oscillations in trial i, we need to first identify the equilibrium position and then measure the time it takes for the object to complete one full cycle of oscillation.

what types of shafts satisfy the notion that the twisting deformation does not distort cross sections of the shaft
The shafts that satisfy the condition that the twisting deformation does not distort their cross sections are called circular or circular-polar shafts.
What are circular or circular-polar shafts?
In these types of shafts, the cross-sectional shape remains constant, and the deformation is uniform throughout the length of the shaft.
Circular-polar shafts have a constant cross-sectional diameter, and the axis of the shaft is a polar axis, which means it passes through the centroid of the cross-section. This results in a uniform distribution of stress and strain, and therefore, the cross-section remains unchanged under torsional loads.

A(n) ______ skid occurs when your front tires begin to lose contact with the road surface.A. UndersteerB. Evasive steeringC. HydroplaningD. Evasive braking
A(n) Understeer skid occurs when your front tires begin to lose contact with the road surface.
What is Hydroplaning
Hydroplaning is a phenomenon that occurs when a vehicle's tires lose contact with the road due to a thin layer of water. This can cause the driver to lose control of their vehicle and skid across the surface. It is most likely to occur when the road is wet and the vehicle is travelling at speeds above 35 mph. In order for hydroplaning to occur, a certain depth of water is necessary. The depth of the water must be between 1/12th and 1/10th of an inch. Drivers can reduce the risk of hydroplaning by making sure that their tires are properly inflated and that the treads are not worn down. Additionally, drivers should reduce their speed when driving on wet roads and increase their following distances. It is important to remain aware and alert when driving on wet roads and be prepared for the potential of hydroplaning.

testing of a switch is being discussed. technician a says a switch can be tested with a voltmeter. technician b says to use a fused jumper wire to see if the switch is operating. who is correct?
Both technician A and technician B are correct, as different methods can be used to test a switch depending on the situation and the type of switch being tested.
Technician A is correct in stating that a switch can be tested with a voltmeter. This is a common method used to determine if a switch is functioning properly. When testing a switch with a voltmeter, the voltmeter is set to measure the voltage at the switch terminals. The switch is then activated and the voltage is checked to determine if it has changed. If the voltage changes, it indicates that the switch is functioning properly. This method is useful for testing switches in electrical circuits, as it allows technicians to quickly determine if the switch is working correctly and, if not, where the problem lies.
Technician B is also correct in stating that a switch can be tested using a fused jumper wire. This method is used to physically test the operation of the switch. A fused jumper wire is connected to the switch and a fuse is used to protect against electrical problems. The switch is then activated and the jumper wire is used to verify that the switch is functioning properly by checking if the circuit is complete. This method is often used in combination with a voltmeter to provide a comprehensive test of the switch.
In conclusion, both technicians are correct in their statements, as different methods can be used to test a switch depending on the situation and the type of switch being tested. The voltmeter test is useful for determining if the switch is functioning properly in an electrical circuit, while the fused jumper wire test is used to physically verify the operation of the switch.

consider a stokes flow due to a sphere rotating near a wall, argue from kinematic reversibility weather or not the rotating sphere will experience a force pushing it away or drawing it into the wall
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.
What is the reversibility about?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.
