stress concentration does have effects on brittle materials on their behavior even under static loads. however, the geometric stress concentration is often ignored for cast-brittle materials, such as cast iron. why? choose the best answer.

Answers

Answer 1

Because local yielding or deformation occurs in ductile materials and thus reduces the concentration, stress concentration in ductile materials is not as severe as it is in brittle materials.

In the part design, a stress concentration is a location where the stress is much higher than it is elsewhere. The geometry of the part's sharp corners, holes, notches, or grooves is what most frequently causes stress concentrations. In order to ensure the component functions properly and safely, it is crucial to analyze it for stress concentration. The system's balance may be further hampered and serious repercussions may result if the fabricated or produced component is not entirely functioning under stress. The term "stress concentration" refers to a location that exhibits an abrupt geometric transition or discontinuity and is characterized by high localized stress relative to the body's average stress.

Answers

Technician A says that when disconnecting the battery, the negative terminal should be disconnected first. Technician B says that baking soda and water will remove oxidation from battery terminals. The technician who is correct is Technician A.

Why should you first disconnect the negative terminal when removing a battery?

It is critical to detach the negative side of the battery first; otherwise, an electrical short might occur if the positive is removed first.

The ground cable is the negative () cable; it is always linked to the frame or body metal and can be securely detached first without producing sparks. Similarly, reconnect the positive cable before attaching the negative cable.

technician a says that a vehicle will tend to pull toward the side with the most positive camber. technician b says that a progressive-rate spring offers a soft ride but can also carry a heavier load. who is correct?

Answers

Both technicians are correct in saying that a car will typically pull to the side with the most positive camber and that a progressive-rate spring provides a smooth ride while also being able to support a heavier load.

Positive Camber: When your wheels are slanted outward, your vehicle's stability is increased. Negative Camber: High performance cars with superior cornering requirements frequently use negative camber because it gives the driver more control. Positive camber will make your automobile pull to either side, which will make it easier to steer and more stable on uneven terrain. Because of this, off-road vehicles frequently employ positive camber. It can also be observed on vintage race vehicles with softer suspension systems. It is applied to steering and suspension design. Positive camber refers to a wheel's top being farther out than its bottom (or tilted away from the axle).

While, for, are pre-test loops.

What is loop?
A loop is a set of instructions that are repeatedly carried out in computer programming until a specific condition is met. Typically, a certain procedure, like getting and altering a piece of data, is carried out, and then a condition, like whether a counter has reached a specific number, is verified. If not, the subsequent command in the sequence directs the computer to go back to the first and repeat the process. If the condition has indeed been met, the subsequent instruction either branches outside of the loop or "falls through" to the following sequential instruction. A loop is a basic programming concept that is frequently utilised when creating programmes.

Electronics is an area of physics and electrical engineering that studies electron emission, behaviour, and consequences utilising electronic devices. Electronics varies from classical electrical engineering because it uses active devices to influence electron flow via amplification as well as rectification, whereas classical electrical engineering only uses passive effects to control electric current flow, such as resistance, capacitance, and inductance. Electronics has had a significant impact on the evolution of modern society. The discovery of the electron in 1897, followed by the invention of the vacuum tube, which could amplify and rectify minuscule electrical impulses, marked the beginning of the field of electronics and the electron age.

The correct answer is a. brittle deformation. therefore the correct option is (a) option.

Brittle deformation is when rocks fail as rigid solids. The rocks will break, rather than bend, under these conditions to produce fractures. Brittle deformation occurs along discrete planes in the rock instead of involving the rock body as a whole.Brittle materials include glass, ceramic, graphite, and some alloys with extremely low plasticity, in which cracks can initiate without plastic deformation and can soon evolve into brittle breakage.

7. the hlsm below shows an alarm system that sets a single-bit output alarm to 1 when the average temperature of four consecutive samples meets or exceeds a user-defined threshold value. the system has a 32-bit unsigned input ct, which is the current temperature, and a 32-bit unsigned input wt, which is the warning threshold. a single-bit input clr when 1 disables the alarm and the sampling process. fill in the blanks with tmp0, tmp1, tmp2, tmp3 and avg for the components in the datapath. (answers are case sensitive)

Answers

Shift register components can be found in the data route as A, B, C, and D. Take tmp0, tmp1, tmp2, and tmp3 as the outputs of the flip-flops A, B, C, and D, respectively. After the initial shift, when tmp ld is set to 1, the following occurs:

tmp0 (o/p of A) = CT

similarly, tmp1 (o/p of B) = tmp0

tmp2 (o/p of C) = tmp1

tmp3 (o/p of D) = tmp2.

Now, the output of A, B, C, and D would all be zero because tmp0, tmp1, and tmp2 were all initialised to zero. Flip flop A alone has the output, which is CT. These outputs are added in two stages: first, A is added to B (i.e., CT+tmp0), then C is added to D (i.e., tmp1+tmp2), and finally, the outputs of the first stage are added in the second stage before being shifted right by two bits, or divided by four. As a result, E flipflop stores the average of all the outputs, which is (CT + tmp0 + tmp1 + tmp2) /4.

So, A= tmp0 which eventually gets CT,

B=tmp1 which eventually gets tmp0 (=0),

C=tmp2 which eventually gets tmp1 (=0),

D=tmp3 which eventually gets tmp2 (=0),

E= avg of tmp0,tmp1,tmp2,tmp3 (=CT/4).

What is tmp?

A temporary file, or tmp is one that has been created to hold data temporarily, either for a program's interim needs or for later transfer to a permanent file. Computer programmes may produce it for a variety of reasons, including as when they are unable to allot enough memory for their duties, when they are working with data that is larger than the architecture's address space, or as a crude kind of inter-process communication.

What is method?
A process connected to a message and an object is referred to as a method with object-oriented programming (OOP). An object is made up of state information and behaviour, which together make up the interface that outlines how any of the object's numerous consumers may use it. A method is a consumer-parametrized behaviour of an object. Behaviors are represented as methods, while data is represented as an object's properties. For instance, a Window object might contain properties like open and close while also having methods like open and close. In class-based programming, objects are instances of a certain class, and methods are defined within the class. One of the most crucial features that a method offers is method overriding, which allows the same name (for example, area) to be used for numerous distinct types of classes.

If we consider a rectangular bath tub, we can express its volume as follows:

Volume (V) is determined by length, breadth, and height, where the rectangular bathtub's base has dimensions of 14 ft2 in length, breadth, and height (1)

When the rate of rise of the volume is 0.8 ft3/min, differentiation is used to implicitly differentiate 14h with regard to t, resulting in:

In air conditioning and heat pump systems and chiller, refrigeration leaks are fairly prevalent and can be challenging to find. It requires the appropriate tools and a lot of practise. According to Refrigeration Technologies, the company that created the BigBlu Micro Leak Detector Solution, there are several sorts of leaks. During your maintenance experience, you will come into contact with each one at some point.

Standing Leaks (SL) are leaks that can be found when the system is fully equalised and at rest (off). This must include defrosted freezer evaporative coils. Thankfully, SL leaks are the most frequent of all.

. for the problem in (1), design a flash converter with 3-bit resolution to represent the 1 khz sinusoid with an amplitude of 5-volt p-p. assume that the sinusoid has 2.5-volt dc level (that is, the signal swings between 0 and 5 volt). use lm339 and priority encoder 74ls148. examine the datasheets for these chips carefully. you may use the design in fig. 1. however, you need to choose the reference level carefully as an incorrect reference level may result in erroneous responses. make sure that you set the reference level in order to accurately represent the signal.

Answers

The flash converter should have a resolution of 3 bits in order to accurately represent the 1kHz sinusoid with an amplitude of 5-volt p-p.

What is volt?
The definition of a "volt," a measure of electric potential, commonly known as electromotive force, is "the potential difference between the two points of the a conducting wire carrying a continuous current equal to 1 ampere, when the power consumed between these points was equal to 1 watt." In other words, when a current of just one ampere travels through a resistance of one ohm, a potential of one volt emerges across that resistance. Similar to water pressure, "voltage" (V) represents the potential of energy to travel. Voltage has properties similar to those of water flowing through pipes. It's called the "water-flow analogy" in this case.

The sinusoid should have a 2.5-volt dc level, so the signal should swing between 0 and 5 volts. The flash converter should use an LM339 and a priority encoder 74LS148.

Jupiter's band structure is composed of contrasting regions known as belts and zones. On the diagram, label the belt and zone regions and their corresponding directions of convection.

Answers

Jupiter's band structure which is composed of contrasting regions known as belts and zones is given in the attached image.

What are belts?

The asteroid belt is a torus-shaped area in the Solar System lying roughly between Jupiter and Mars orbits. It is home to a large number of solid, irregularly shaped things of various sizes, but far smaller than planets, known as asteroids or minor planets.

Zones are lighter bands seen in the atmospheres of gas giants. They are found at higher elevations and are high-pressure areas. In the zones, there is an internal updraft.

It is to be noted that Jupiter, the fifth planet from our Sun, is by far the biggest planet in the solar system, weighing more than twice as much as all the other planets combined. Jupiter's bands and swirls are actually frigid, windy clouds of ammonia and water floating in a hydrogen and helium atmosphere.

a floor can be dented by the application of too much stress. what stress is caused by a 70 kg woman in high-heeled shoes (assume a 6.0- mm -diameter heel) standing on one heel?

Answers

The stress caused by a 70 kg woman in heeled shoes (assume a 6.0- mm -diameter heel) standing on one heel is 0.02638699 N/m.

What is stress?

Stress is a term used to define the strength of the forces that lead to deformation. The general definition of stress is force per unit area. Tensile stress is what we refer to when forces draw on an object and induce its elongation, similar to how an elastic band stretches.

Given that mass, m = 70 kg

diameter = 6.0 mm = 0.6 cm

then, radius,

r = 0.35 cm

= 0.0035 m

A = areas of cross-section

[tex]\pi r^2 \; and\;\;stress = \dfrac{mg}{a}[/tex]

Putting the values in the formula

[tex]stress = \dfrac{(70) (9.8) }{\pi (0.0035)^2} = 0.02638699 \; N/m^2[/tex]

Therefore, the stress caused by the woman is 0.02638699 N/m2.

What is MVC Architecture?

Model-view-controller is a software architecture style for building user interfaces that divides the underlying program logic into three interrelated pieces. This is done to isolate internal information representations from how data is communicated to and accepted by the user.

The Model-View-Controller (MVC) architectural pattern, on the other hand, divides an application into three key logical components: the model, the view, and the controller. Every one of these components is designed to handle particular parts of an application's development.
