The system will have an overshoot for a step input. The amount of overshoot can be calculated using the damping ratio and natural frequency of the closed-loop system.
In order to determine if the system under closed-loop pi control will have an overshoot for a step input, we need to calculate the values of the closed-loop transfer function poles and zeros. The transfer function for a closed-loop pi control is given by:
G(s) = (kp + ki/s) / (1 + ki/s)
For case a (kp=2, ki=1), the closed-loop transfer function becomes:
G(s) = (2 + 1/s) / (1 + 1/s)
The poles of this transfer function are the roots of the denominator:
1 + 1/s = 0
s = -1
Therefore, the system will not have any overshoot for a step input.
For case b (kp=1, ki=3), the closed-loop transfer function becomes:
G(s) = (1 + 3/s) / (1 + 3/s)
The poles of this transfer function are the roots of the denominator:
1 + 3/s = 0
s = -3

How a car break works?
The break system of a car is composed by several items that are always working together to slow down and bring a vehicle to a complete stop. It also has the function of keeping the car stationary when it is parked. In general, this system has two manual activation modes: the lever and the pedal, with the exception of vehicles adapted for people with disabilities.
Most vehicles today use the disc brake system. Disc brakes work by using pads, which are held inside a hydraulic caliper, receiving pressure to brake. Such pads generate friction on a disc, which makes the vehicle stop permanently.
The drum brake is another type, being older and dependent on the famous linings to cause friction in the wheel and stop the vehicle. A hydraulic cylinder makes the plies move inside the drum, which is a hollow part fastened with screws and attached to the wheels. This type of brake is on the rear wheels, for the most common models.

What are vehicles?A vehicle is a piece of equipment, typically with wheels and an engine, used for land-based transportation of people or goods. Cars, buses, and trucks are examples of road vehicles. Farm vehicles include tractors.
Vehicle type refers to a group of power-driven vehicles that share all crucial aspects of their engines, cars, and OBD systems.
When a vehicle is 500 feet away, the driver must dim his headlights.
Avoid looking directly into the light when a car is coming at you; instead, slow down. At least 30 minutes before dusk, headlights must be activated. It is also important to keep in mind that a lower headlight beam improves the driver's ability to see in fog.
Thus, it should be 1000 feet distance.

Determine the carburizing time necessary to achieve a carbon concentration of 0.30 wt.% at a position of 4 mm into an iron-carbon alloy that initially contains 0.10 wt.% C. The surface concentration is to be maintained at 0.90 wt.% C, and the treatment is to be conducted at C. Use the diffusion data for -Fe in Table 5.2
The carburizing time necessary to achieve a carbon concentration is 31.35 hours
How to find the Carburizing Time?To determine the carburizing time necessary to achieve the given carbon concentration, we will use the equation:
(Cs - Cx)/(Cs - C0) = ERF(x/2√Dt)
where;
Cs is Concentration of carbon at surface = 0.90
Cx is Concentration of carbon at distance x = 0.30
Distance x = 4 mm = 0.004 m
C0 is Initial concentration of carbon = 0.10
ERF() = Error function at the given value
D = Diffusion of Carbon into steel
t = Time necessary to achieve given carbon concentration ,
Thus, plugging in the relevant values gives;
(Cs - Cx)/(Cs - C0) = (0.9 - 0.3)/(0.9 - 0.1)
= 0.6/0.8 = 0.75
now, ERF(z) = 0.75 and as such using ERF table, we can say that;
Z = 0.814. Thus;
(x/2√Dt) = 0.81
Using the table of diffusion data, we have;
At a temperature of (1100°C) or 1373 K, we have;
D = 5.35 × 10⁻¹¹ m²/sec.
Calculating the carbonizing time by using the equation z = (x/2√Dt);
where;
t is carbonizing time
Thus;
0.814 = (0.004/(2 × √5.35 × 10⁻¹¹ × √t))
0.814 = 0.004 /(1.4628 × 10⁻⁵ × √t)
0.814 × 1.4628 × 10⁻⁵ × √t = 0.004
1.19072 × 10⁻⁵ × √t = 0.004
√t = 0.004/(1.19072 × 10⁻⁵)
√t = 335.93
t = 112848.96 seconds
Converting to hours gives;
t = 112848.96/3600
t = 31.35 hours
Therefore, the carburizing time necessary to achieve a carbon concentration is 31.35 hours

Explanation:
Which is not one of the primary characteristic of unit testing:
Answer:
Unit testing is a software development process in which the smallest testable parts of an application, called units, are individually and independently scrutinized for proper operation. This testing methodology is done during the development process by the software developers and sometimes QA staff. The main objective of unit testing is to isolate written code to test and determine if it works as intended.
Unit testing is an important step in the development process, because if done correctly, it can help detect early flaws in code which may be more difficult to find in later testing stages.
Unit testing is a component of test-driven development (TDD), a pragmatic methodology that takes a meticulous approach to building a product by means of continual testing and revision. This testing method is also the first level of software testing, which is performed before other testing methods such as integration testing. Unit tests are typically isolated to ensure a unit does not rely on any external code or functions. Testing can be done manually but is often automated. It might be helpful
