The likely difference between urban planning for a very old city and urban planning for a new community built very recently is: "Urban planning for the very old city will present a more difficult array of problems." (Option B)

<h3>Why will Urban planning for a very old city present a more difficult array of problems?</h3>

Urban planning, also known as town planning, infrastructure planning, regional planning, or rural planning, is a technical and political process that focuses on the design and development of land use and the built environment, including air, water, and the infrastructure that passes through and out of urban areas, such as transportation, communications, and distribution networks, as well as their accessibility.

Cities that are poorly designed and managed also introduce new hazards that threaten to destroy present development benefits. Natural disasters can become disasters due to a lack of suitable infrastructure and services, dangerous housing, and inadequate and bad health care.

Assume that in orthogonal cutting the rake angle is 15° and the coefficient of friction is 0.15. a. Determine the percentage cha
alexira [117]

Answer:

Δr=20.45 %

Explanation:

Given that

Rake angle α =  15°

coefficient of friction ,μ = 0.15

The friction angle β

tanβ = μ

tanβ = 0.15

β=8.83°

2φ +  β - α  = 90°

φ=Shear angle

2φ + 8.833° - 15° = 90°

φ = 48.08°

Chip thickness r given as

r=\dfrac{tan\phi}{cos\alpha +sin\alpha\ tan\phi}

r=\dfrac{tan48.08^{\circ}}{cos15^{\circ} +sin15^{\circ}\ tan48.08^{\circ}}

r=0.88

New coefficient of friction ,μ'  = 0.3

tanβ' = μ'

tanβ' = 0.3

β'=16.69°

2φ' +  β' - α  = 90°

φ'=Shear angle

2φ' + 16.69° - 25° = 90°

φ' = 49.15°

Chip thickness r' given as

r'=\dfrac{tan\phi'}{cos\alpha +sin\alpha\ tan\phi'}

r'=\dfrac{tan44.15^{\circ}}{cos49.15^{\circ} +sin49.15^{\circ}\ tan44.15^{\circ}}

r'=0.70

Percentage change

\Delta r=\dfrac{r-r'}{r}\times 100

\Delta r=\dfrac{0.88-0.70}{0.88}\times 100

Δr=20.45 %

horrorfan [7]

Answer:

B.29

Explanation:

In general purpose acme thread:

  Nominal depth of thread=0.5ltimes Pitch

  Included angle =29 degrees

Generally Acme thread are following types

  1.General purpose(G) Acme

  2.Centralizing(C) Acme

  3. Stub Acme  

Centralizing(C) Acme threads have tighter tolerance during manufacturing as compare to General purpose(G) Acme  threads.
