When we are on an airplane, a little bit after takeoff, why do the engines suddenly sound like they’re reducing in power?

Answers

The sudden reduction in engine noise that passengers may notice after takeoff is a normal part of the takeoff process and is done to make the flight more efficient and comfortable.

Here is the principle behind flight

The sudden reduction in engine noise or thrust that passengers sometimes hear and feel shortly after takeoff is due to a reduction in engine power as the airplane reaches a certain altitude and speed. This is a normal part of the takeoff process and is known as the "reduction in takeoff thrust" or "thrust reduction".

During takeoff, the aircraft's engines produce a high amount of thrust to get the airplane off the ground and up to a safe altitude. Once the airplane reaches a certain altitude and speed, the pilot reduces the engine power to a lower setting, which is more efficient and produces less noise. The reduction in power is often noticeable to passengers, as the noise and vibration from the engines decrease.

The exact timing of the thrust reduction can vary depending on the airplane type, airline procedures, and other factors. In some cases, the thrust reduction may occur shortly after takeoff, while in other cases, it may occur a few minutes later.

You are tasked with a designing a circuit that accepts a stream of binary digits, and that outputs a 0 whenever the pattern 10 takes place. Otherwise, the output is 1.


Part A [2 marks] Draw the state diagram for the above description. Use a Moore model, i.e., a Finite State Machine (FSM) where the outputs are specified within the states.


Part B [2 marks] Assign binary values to your states using an encoding that requires the minimum number of digits.

Part C [2 marks] Obtain the binary-coded state table.

Part D [4 marks] Assuming the use of JK flip-flops, derive both the flip-flop input equations in addition to the output equation.

Part E [4 marks] In the space below, draw the logic diagram of the circuit you designed above.

Answers

To draw the state diagram for the given description, we need to identify the states and transitions based on the behavior of the circuit. In this case, we have two states: State A (output = 1) and State B (output = 0).

The transitions are as follows:

From State A, when the input is '1', transition to State B.From State B, when the input is '0', transition to State A.

Part B:

To assign binary values to the states, we can use a binary encoding that requires the minimum number of digits. Since we have two states, we can assign '0' to State A and '1' to State B.

Part C:

Based on the states and transitions, we can create a binary-coded state table. Here's an example of how the table would look:

| Present State | Input | Next State | Output |

|---------------|-------|------------|--------|

| A             | 0     | A          | 1      |

| A             | 1     | B          | 1      |

| B             | 0     | A          | 1      |

| B             | 1     | B          | 0      |

Part D:

Assuming the use of JK flip-flops, we can derive the flip-flop input equations and the output equation based on the state table. Here's an example of the equations:

J_A = 0

K_A = 0

J_B = 1

K_B = Q_A

Output = Q_A

Part E:

To draw the logic diagram of the circuit, we would use the derived flip-flop input equations along with the output equation to implement the circuit using logic gates.

Thus, the circuit would include JK flip-flops, AND gates, and possibly other gates depending on the specific implementation.

what is a roller support​

Answers

Answer:

A roller support is a type of structural support commonly used in engineering and construction. It consists of a freely rotating roller, usually made of steel or other durable material, that is placed between a structural member and its support, allowing the member to move freely along a particular direction.

The roller support is designed to accommodate movements due to thermal expansion, contraction, or any other external factors that may cause the structural member to move. The roller support can only resist vertical loads, and it allows horizontal movement in one or more directions.

Roller supports are often used in bridge construction, where they are installed between bridge beams and piers to allow for longitudinal movement caused by temperature changes, wind loads, or traffic loads. They are also used in industrial applications to support large pipelines or ductwork, where the structure may need to move or shift due to thermal expansion or contraction.

Overall, the roller support is a simple yet effective method of providing structural support while allowing for movement in specific directions, reducing stress and strain on the structure and increasing its overall durability and longevity.
