Answers

Answer 1

If a first order system's characteristic value, 8, is smaller than zero, we may say that it is dynamically stable. Rolling convergence is the term used to describe the motion, which is a damped roll rate.

Explain the aircraft dynamic modes ?Two parameters can be used to define oscillating motions: the duration of one full oscillation and the duration needed to damp to half-amplitude, or the duration needed to double the amplitude for a dynamically unstable motion. A long-period oscillation known as a phugoid mode and a short-period oscillation known as the short-period mode make up the two different oscillations that make up the longitudinal motion.The "phugoid mode," which has a longer period, is characterised by large amplitude variations in air speed, pitch angle, and altitude but almost no variations in angle of attack.As the aircraft tries to return to the equilibrium level-flight condition from which it had been disturbed, the phugoid oscillation is a slow exchange of kinetic energy (velocity) and potential energy (height) around some equilibrium energy level.

while examining a heavy, flat steel plate bolted to the oil pan rails and main bearing caps, technician a suggests it is used to stiffen the crankcase to reduce torsional twisting. technician b says the plate is used to prevent oil from splashing up onto the cylinder walls and causing high oil consumption. who is correct?

Answers

Technician a is correct because that he says claims that it is utilized to strengthen the crankcase in order to prevent torsional twisting.

Engine heat ultimately determines what temperature the oil reaches and is the most common cause of high oil pressure. Oil pressure can also increase due to malfunctioning engine parts. Low oil level is the most frequent and simplest to fix reason for low pressure. While regular oil changes are important, it's also crucial to regularly check your motor oil level and top it off as needed in between oil changes. A beam will twist when a torque is applied, and this is known as torsional twisting. It is applied methodically to screws, nuts, axles, drive shafts, etc., and is also produced more randomly under service conditions in car bodies, boats, airplane fuselages, bridges, springs, and many other structures and components.

determine the 0.2% offset yield strength from the stress-strain data. the sample is cylindrical with a radius of 1.25 mm.

Answers

By building a parallel line offset from the linear stress-strain line by 0.002 strain, the 0.2% offset yield strength is computed.

Because the yield strength of steel, according to ASTM, is 0.2% permanent strain (offset). This definition serves as a good "rule of thumb" for the majority of steels and typically equates to a 0.5% total strain. The predetermined amount of permanent strain is set along the strain axis of the graph, to the right of the origin, in order to determine yield strength. Figure 5 designates it as Point. Point (D) is crossed by a straight line that has the same slope as the first part of the stress-strain curve.

a heating element operates on 115 v. if it has a resistance of 15.4 ohms, what current, in amps, does it draw?

Answers

The current is 7.46A. A stream of charged particles, such as electrons or ions, travelling through an electrical conductor or a vacuum is known as an electric current.

How to calculate current?Electric currents are streams of electrically charged particles, such as electrons or ions, moving through a conductor or a void. It is calculated as the net rate of electric charge flowing through a surface or into a control volume.Electric currents generate magnetic fields, which are used in motors, generators, inductors, and transformers. In typical conductors, they cause Joule heating, which ignites incandescent light bulbs. To transfer information via communications, time-varying currents produce electromagnetic waves.Current is obtained by merely dividing the magnitude of a charge by the measurement duration. Current can be calculated using the equation I = Q t, where I denotes current, Q denotes charge, and t denotes time.

Given value

Voltage = 115v

Resistance = 15.4 ohms

The CMRR the device is 5 : 1. The CMRR can be meant as ratio between common model gain and differential model gain.

CMRR refers to the ratio of the common-mode gain with differential-mode gain. The example of CMRR happens when a differential input change of Y volts produces a change of 1 V at the output, and a common-mode change of X volts produces a similar change of 1 V, then the CMRR is X/Y.

Assume  a common-mode input of 1 v, the output of the device is 100 mv is Y

Common mode gain = Vout/Vin

Common mode gain = 0.01/1 = 0.01

Differential mode gain = 1

Then,

CMRR = Common mode gain/ Differential mode gain

CMRR = 0.01/1 = 0.01

Assume when the device has a differential input of 2 mv, the output of the device is 10 v is Y

Common mode gain = Vout/Vin

Common mode gain = 10/2

Common mode gain = 5

Differential mode gain = 10/2-1 = 10

Which statement about the filtering result of the following ACL is true?
Router(config-ext-nacl)# permit tcp 192.168.1.0 0.0.0.255 host 192.168.100.1 eq 80
Router(config-ext-nacl)# deny tcp any host 192.168.100.1 eq 80

Answers

If you want to prevent traffic from entering the internal server network, use the command ip access-list 6 deny 192.168.1.00.0.0.255.

How does the router's ACL filter work?A set of rules known as a "Access Control List" (ACL) governs how any traffic passing through routers is allowed, permitted, or denied. By filtering and managing the traffic flow between routers, it functions at layer 3 to ensure security.According to the source IP address, destination IP address, and port numbers, packet filtering occurs in the Extended access list. Services will either be allowed or blocked according to an extended access list. From 100 to 199, and 2000 to 2699, are the extended ACL ranges that are produced.If you want to prevent traffic from entering the internal server network, use the command ip access-list 6 deny 192.168.1.00.0.0.255.

It is possible to change the slip and speed at which the maximum torque occurs if the rotor resistance is raised in some way.

In the case of slip ring or wound rotor type motors, this can be accomplished by adding external resistance to the rotor circuit. This occurs when the rotor conductors are shorted-circuited and there is a transformer action between the stator winding and the rotor winding. The rotor experiences a strong current flow as a result. The starting torque is also impacted if the applied starting voltage is decreased in order to reduce this high starting current.

water flows past a flat plate that is oriented parallel to the flow with an upstream velocity of 0.5 m/s. determine the approxi- mate location downstream from the leading edge where the bound- ary layer becomes turbulent. what is the boundary layer thickness at this location?

Answers

Along with a flat, smooth plate, the following variables have an impact on the thickness of the boundary layer formation: The fluid's kinematic viscosity affects the thickness of the boundary layer.

As the distance from the leading edge gets less, the boundary layer thickness gets thinner. The narrow region of flow next to a surface known as a boundary layer is the layer in which friction between the fluid and solid surface affects the flow [2]. The theory was founded on certain significant System. In some areas, the viscosity of the fluid in motion cannot be ignored. The thickness of the boundary layer at a distance from the leading edge is discovered to be 5 mm for laminar flow over a flat plate.

technician a says that a transaxle first-gear ratio of 3.5:1 means input torque is increased by 3.5 times. technician b says that a transaxle first-gear ratio of 3.5:1 means input speed is increased by 3.5 times. which technician is correct?

Answers

The technician A is right. When the transaxle's first gear is 3.5:1, the input torque is multiplied by 3.5. The output torque is thus 3.5 times greater than the input torque. The first-gear ratio of the transaxle has no impact on the input speed.

What is a torque?

The force that can force an object to spin along an axis is measured as torque. In linear kinematics, force is what drives an object's acceleration. Similar to this, an angular acceleration is brought on by torque. As a result, torque can be thought of as the rotational counterpart to force.
