Explanation:

I have a project and everyone in the world will know about it.

Answer:

both

Explanation:

Answer:

a. 27.65 N b. 5.93 cm/s c. 0.03n where n = 1,2,3....

Explanation:

a. Since Young's Modulus E = stress/strain = σ/ε and σ = εE, we find the stain in the steel wire by finding its strain at 20°C.

Now Δl = lαΔθ where l = length of steel wire = 1.000 m, α = coefficient of linear expansion of steel = 11.0 × 10⁻⁶ C⁻¹ and Δθ = change in temperature = 20 °C - 60 °C = -40 °C

The strain  ε = Δl/l = αΔθ = 11.0 × 10⁻⁶ C⁻¹ × -40 °C = -4.4 × 10⁻⁴

σ = T/A= εE, where T = tension in steel wire and A = cross-sectional area of steel wire

T = εEA = εEπd²/4 where d = diameter of wire = 2.000 mm = 2 × 10⁻³ m

So,

T = εEπd²/4

= 4.4 × 10⁻⁴ × 2× 10¹⁰ Pa × π ×  (2 × 10⁻³ m )²/4

= 27.65 N

b. The velocity of the travelling wave at this lower temperature is

v = √(T/μ) where μ = mass per unit length = ρl where ρ = density of steel wire = 7.86 × 10³ kg/m³ and l = length of wire = 1.000 m

v = √(T/μ)

= √(T/ρl)

= √(27.65 N/(7.86 × 10³ kg/m³ × 1.000 m))

= √(27.65 N/7.86 × 10³ kg/m²)

= √(0.3517 × 10⁻² N/kg/m²)

= 0.05931 m/s

≅ 0.0593 m/s

= 5.93 cm/s

c. To find the allowable frequencies, we first find the fundamental frequency f₀ = v/2l

= 0.0593 m/s ÷ (2 × 1 m)

= 0.0593 m/s ÷ 2

= 0.0297 Hz

≅ 0.03 Hz

So, the allowable modes of frequency are multiples of f₀, that is fₙ = nf₀ where n = 1,2,3....

So, fₙ = 0.03n Hz where n = 1,2,3....

The apartments probably described in the question can be termed as "Tenements" and families living there have relatively poor life standard .

What are Tenements?

Tenements are a type of low-cost, overcrowded housing that was common in many urban areas in the late 19th and early 20th centuries.

They were often small, cramped, and in poor condition, with limited access to light, air, and basic amenities such as electricity.

Tenements were frequently overcrowded, with many families living in a single apartment, and they often lacked proper sanitation facilities.

This type of housing was most commonly associated with poverty and squalor, and it was a major factor in the growth of slums in many cities.

The maximum current allowed in a 1.0 kΩ, 1/4 W resistor to prevent damage is 0.25 mA.

The maximum current an 1/4 W, 1 kΩ resistor can carry without damage is dependent on two factors: 1) the wattage rating of the resistor and 2) the resistance of the resistor.

Since the power rating for the 1 kΩ resistor is 1/4 W, it can carry a maximum current of:

IMax = (P/R) = (1/4)/1000 = 0.25 mA

An early type of capacitor is known as the Leyden jar. Devices that store a static electric charge are generally referred to as capacitors. Photocopiers utilize static electricity to attract toner particles onto a charged drum.

The Leyden jar is considered an early type of capacitor. It was invented in the 18th century and consisted of a glass jar filled with water or another conductive liquid. The jar had a metal electrode inside and another metal electrode on the outside. When a voltage was applied to the electrodes, the jar would store an electric charge.

The general term for devices that store a static electric charge is capacitors. Capacitors are widely used in electrical and electronic systems to store and release electrical energy. They are composed of two conductive plates separated by an insulating material called a dielectric. When a voltage is applied across the plates, the capacitor stores electric charge, and this charge can be discharged later.

Photocopiers utilize static electricity in their operation. A photocopier's drum is coated with a photosensitive material. Initially, the drum is given a positive charge through a process called corona discharge, where static electricity is used to ionize the surrounding air and charge the drum. As the charged drum rotates, it passes near the original document to be copied. The photosensitive coating on the drum attracts negatively charged toner particles from the toner cartridge onto its surface, forming an electrostatic image of the document. This image is then transferred onto paper, and the toner is fused to the paper, creating a copy of the original document.

Question one: There were seven elements of the design listed in the unit. Please name five of them, and give a short description of each.

Answer: line, shape, space, value, form, texture, and color.

Line: I thin or thick drawn/made considered a moving point in space, It is one-dimensional and can vary in width, direction, and length.

Shape: a two-dimensional form tends to be colored or circled/lined

Space: the feeling of depth or three dimensions there’s a positive and negative space, Positive space is filled in or used to be a part of the drawing, the negative can be the empty space in the painting

Value: it sometimes light and dark colors it is used a scale at times and used to make high or low contrast

Form: has a physical being and the other could be like a message from an image,

Textures: surface quality, there are real and actual textures, some textures aren't as they seem or made something created to look like something it is not

Color: the element of art

Question two: There were also seven principles of the design listed in the unit. List five of the principles of design and explain what each means.

Answer: Emphasis, contrast, balance, pattern, and rhythm.

Emphasis: The principle of art that helps the audience put the story of a painting together in their own minds. Any object or area of emphasis is called a focal point.

Contrast: The arrangement of opposite elements and effects. For example, light and dark colors, smooth and rough textures, large and small shapes.

Balance: The distribution of the visual weight of objects, colors, texture, and space.

Pattern: A design in which lines, shapes, forms, or colors are repeated.

Rhythm: The principle of design that suggests movement or action.

Question three: There are three different ways that balance is used. Please list the three different ways and explain what each means.

Answer: Symmetrical, asymmetrical, and radial

Balance is the principle of design that teaches the work of art should be in harmony, and that its sides “weigh” the same so that it doesn’t look uneven. The three types of balance are symmetrical, asymmetrical, and radial.

Symmetrical balance means the two parts of the art are identical. If we were to separate the picture or art piece in the middle, the two sides would be equal, presenting the same elements and weighing the same.

An asymmetrical balance occurs when the two parts of the painting or work of art are not the same, yet they weigh the same. They are in harmony, but they have different components. For example, maybe one side presents larger elements, but the other side has brighter colors, so there is no tension, and the observer sees composure on the piece.

Radial balance is presented as elements gathered around the joined center. They can go towards it, or from it, but they seem as if to radiate from the same point.

Question four: In the unit, elements of content were discussed. There were four elements of content listed; please name all four and write one sentence explaining each?

Answer: line, shape, form, and texture

Line: Lines, a line is the starting point of every artist's artwork, the line could either be broken, jagged, vertical, horizontal, or diagonal, so basically, a line is the start of the art.

Shape: A shape is anything with edges or is surrounded by an outline, a shape can be anything, but it just has to all end and connect at a certain point to make it a certain shape you want, or you can make your own shape!

According to the problem the diameter of the wire , r1

The outer diameter after wrapping , r2 = 7mm

The thickness of the plastic cover , t

Length of the wire = I

The Thermal conductivity of cover = = k

Current pass through the wire = I

Due to current passing voltage dropped, is V

The temperature = T

Heat transfer coefficient = h

The rate at which the heat is generated in the wire,

q= VI = 8 * 10 =80 Watt

Now for calculating the resistance for each medium .

x1 = 1/hA2 = 1/2 x 2π x 0.0035 x 5 =  0.76 K/ W

x2 = ln r2/r1/2πkl = ln 0.0035/0.0015 /2π 0.15 x 5 = 0.179 K/W

Therefore the total resistance ,

R = x1+x2 = 0.76 +0.179 = 0.939 K/W

Now to calculate the temperature at the interface of the wire,

q= R(T - t)

=> 80 = 0.939(T -30- 273)

T = 378.12 K

Critical radius  is r(critical)

r(critical) = K/h = 0.15/12 = 0.0125 m or 12.5 mm

Answer:Falling or flying objects on a worksite can expose workers to relatively minor injuries, such as cuts and abrasions, as well as more serious injuries, such as concussions or blindness. Working beneath scaffolds or other areas where overhead work is being performed puts workers at risk from falling objects. Flying objects become a concern when workers are using power tools or performing tasks that involve pushing, pulling or prying.

Explanation:General

Always wear hard hats when work is being performed overhead or when other work conditions call for it.

Stack materials securely to prevent them from sliding, falling or collapsing.

Overhead work

Secure all tools and materials to prevent them from falling on people below.

Use toe boards or guardrails on scaffolds to prevent objects from falling. Alternately, use debris nets or catch platforms to grab falling objects.

Machine use

When working with machines or power tools that can produce flying particles, wear safety glasses, goggles or face shields.

Inspect tools prior to use, and be sure all guards are in place and in good working condition.

Allow only properly trained workers to use power-actuated tools.

Cranes/hoists

Whenever possible, avoid working under moving loads.

Erect barricades and post warning signs at hazardous work zones.

Inspect cranes and hoists prior to use to ensure all components are in good working order, including wire rope, lifting hooks and chains.

Never exceed the lifting capacity of cranes and hoists.

Compressed air

Reduce compressed air for cleaning to 30 psi, and always use proper personal protective equipment and guarding.

The magnitude of σ1 that will cause yielding according to the maximum-shear-stress theory is 9.94 ksi.

Yield stress for the zirconium-magnesium alloy, σY = 15.3 ksi

In-plane principal stresses are σ1 and σ2 = −0.54σ1

To find the maximum shear stress theory, the equation used is τ_max=1/2(σ1-σ2)

The maximum shear stress theory states that yielding begins when the maximum shear stress in a part equals or exceeds the shear strength of the material. It is represented as τ_max = τ_yield

Where τ_max is the maximum shear stress in a part and τ_yield is the shear strength of the material. In-plane principal stresses are σ1 and σ2 = −0.54σ1

Let us replace the value of σ2 in terms of σ1σ2 = −0.54σ1,σ1 = 1.85σ2

Substitute the values in the τ_max=1/2(σ1-σ2)

τ_max=1/2(σ1-(-0.54σ1))

τ_max=0.77σ1

Now, τ_yield= σY/2 = 7.65 ksi
