Construct a Mohr circle for the stress element at A in problem 2. Using ruler and compass, draw the Mohr circle to the scale. Dr
serious [3.7K]

Answer:

hello your question is incomplete attached below is the missing diagram to the question and the detailed solution

Answer : principal stresses : 0.82 MPa, -33.492 MPa

              shear stress = 17.157 MPa

              ∅ = 9.09 ≈ 10°

Explanation:

The principal stress ( б1 ) = 0.82 MPa

                                 ( б2 ) = -33.492 MPa

The shear stress = 17.157 MPa

∅ = 9.09 ≈ 10°

attached below is the detailed solution and the Mohr's circle

Consider a cylindrical nickel wire 1.8 mm in diameter and 2.6 × 104 mm long. Calculate its elongation when a load of 290 N is ap
telo118 [61]

Answer:

e = 3.97*10^-4

Explanation:

1.8 mm = 0.0018 m

2.6*10^4 mm = 26 m

Elongation is The ratio between the stretched length and the original length.

e = L/L0

This is calculated with Hooke's law:

e = σ/E

Where

σ: normal stress

E: elastic constant

σ = P/A

Where

P: normal load

A: cross section

A = π/4 * d^2

Therefore:

e = P / (A * E)

e = 4 * P / (π * d^2 * E)

e = 4 * 290 / (π * 0.0018^2 * 207*10^9) = 3.97*10^-4

Combining two strings is called
a_sh-v [17]

Answer:

The appropriate response is "Concatenation". A further explanation is given below.

Explanation:

  • Two or much more strings are almost always concatenated besides space-saving purposes, and therefore could be acknowledged as either a single product.
  • A straightforward example that demonstrates concatenation should be to figure out what it means. How and why that ends up making a term separate from several other phrases is that almost all the messages are stacked together without any open space between each one.

lyudmila [28]

Answer:

The correct option is;

D. Electric meter

Explanation:

An electric meter is a metering device that is used for the measurement of the electric power consumption of an electrical powered tools, a living space or a building

Electric meter readings are used by electric utility company to sell electric power to consumers at a given rate such that it allows the electric utility company to receive payment for the total power supplied, and for the consumer to regulate the amount of power consumed

The electric meters are usually calibrated in kilowatt hour (kWh) and prepaid meter displays the amount of units of power bought, while post paid meters are usually read once each billing period which is usually one month.

A thick spherical pressure vessel of inner radius 150 mm is subjected to maximum an internal pressure of 80 MPa. Calculate its w
ivann1987 [24]

Answer:

by principal stress theory

t = 20.226

by total strain theory

t = 20.36

Explanation:

given data

internal radius r_{1} = 150 mm

pressure p = 80 MPa

yield strength = 300 MPa

poisson's ratio = 0.3

a) by principal stress theory

thickness can be obtained as t

t  = r_{1}\left [ (\frac{\sigma _{y} +p}{\sigma _{y} - 0.5p})^{1/3}-1 \right ]

t = = 150\left [ (\frac{300 +80}{300-0.5*80})^{1/3}-1 \right ]

t = 20.226

b) by total strain theory

m =\frac{\sigma _{y}}{p}

m = \frac{300}{80} = 3.75

we know that

K = \frac{r_{2}}{r_{1} }

\frac{K^{3}+1}{K^{3}-1}= \frac{-2\mu +\sqrt{4\mu^{2}-2(1-\mu)(1-m^{^{2}}))}}{1-\mu}

\frac{K^{3}+1}{K^{3}-1}= \frac{-2*0.3 +\sqrt{4*0.3^{2}-2(1-0.3)(1-3.75^{^{2}}))}}{1-0.3}

\frac{K^{3}+1}{K^{3}-1}= 5.3

k = 1.13

1.13 = \frac{r_{2}}{150 }

r_{2} = 170.36 mm

t = r_{2}-r_{1}

t = 170.36 - 150

t = 20.36
