Answer: the normal longitudinal strain is most nearly 2.5 x 10⁻⁴ mm/mm

Explanation:

Given the data in the question,

we know that;

Normal longitudinal strain = elongation / original length

so we substitute our values

Normal longitudinal strain = 0.5 mm / (2 m x 1000) mm

= 0.5 mm / 2000 mm

= 2.5 x 10⁻⁴ mm/mm

Therefore the normal longitudinal strain is most nearly 2.5 x 10⁻⁴ mm/mm

The statement "Employees are not responsible for their own safety while at work" is false because Employees most certainly are responsible.

A multidisciplinary discipline dealing with the safety, health, and welfare of individuals at work is known as occupational safety and health, often known as occupational health and safety, occupational health, or occupational safety.

An environment that is safe and healthy for workers may minimize injury and sickness expenses, lower levels of absenteeism, boost output and quality, and improve employee morale. In other words, safety benefits the business.

Thus, the statement "Employees are not responsible for their own safety while at work" is false because Employees most certainly are responsible.

Answer:

Explanation:

Answer:  The correct answer is Conservation is the practice of managing resources; preservation is the act of keeping resources undamaged.

Explanation:  This answer has been confirmed as correct.

Answer:

Magnitude of the velocity = 16.82 m/s

Angular direction, θ = 52.41°

Explanation:

As given ,

mass of bullet, m₁= 50g = 0.05 kg

speed of bullet , u₁ = 600 m/s

mass of the block , m₂ = 4 kg

speed of the block before collision , u₂ = 12 m/s

direction , θ = 30°

Now,

Assume that the combined velocity of bullet and block after collision = v

and the direction = θ

Now, from the conservation of momentum in x - direction :

m₁ u₁ + m₂ u₂ = ( m₁ + m₂ ) vₓ

where v = final velocity after collision

u₁ = initial velocity of bullet before collision = 0

m₁ = mass of the bullet before collision = 0.05 kg

u₂  = velocity of block before collision = 12 cos(30° )

m₂ = mass of block before collision

m₁ + m₂ = combined mass of bullet and block after collision = 0.05 + 4

∴ we get

0.05 (0) + 4(12 cos(30° ) ) = ( 0.05 + 4 ) vₓ

⇒ 0 + 4(6√3) = 4.05 vₓ

⇒24√3 = 4.05 vₓ

⇒vₓ = 10.26 m/s

Now, from the conservation of momentum in y - direction :

m₁ u₁ + m₂ u₂ = ( m₁ + m₂ ) [tex]v_{y}[/tex]

where v = final velocity after collision

u₁= initial velocity of bullet before collision = 600

m₁ = mass of the bullet before collision = 0.05 kg

u₂  = velocity of block before collision = 12 sin(30° )

m₂= mass of block before collision

m₁+ m₂= combined mass of bullet and block after collision = 0.05 + 4

∴ we get

0.05 (600) + 4(12 sin(30° ) ) = ( 0.05 + 4 ) [tex]v_{y}[/tex]

⇒ 30 + 4(6) = 4.05 [tex]v_{y}[/tex]

⇒30 +24 = 4.05 [tex]v_{y}[/tex]

⇒54 = 4.05 [tex]v_{y}[/tex]

⇒[tex]v_{y}[/tex] = 13.33 m/s

Now, the magnitude of the velocity = √vₓ² + [tex]v_{y}[/tex]² = √(10.26)² + (13.33)²

                                                           = √105.26 + 177.68

                                                           = √282.95 = 16.82

The angular direction, θ =  [tex]tan^{-1}[/tex]([tex]\frac{v_{y} }{v_{x} }[/tex]) =  [tex]tan^{-1}[/tex]([tex]\frac{13.33}{10.26}[/tex]) = [tex]tan^{-1}[/tex](1.299) = 52.41°

Answer:

Rest periods prevent accidents caused by lack of sleep

Answer:

The value of the cutting speed = 84.85 m/min

a.)The value of the spindle speed = 270.08 rpm

b.)The value of the Power for the unit force = 1.414 W

c.)[tex]u_{max}[/tex] = 0.35,  [tex]u_{min}[/tex] = 0.25

d.)The rate of maximum force to minimum force = 1.4

Explanation:

As given, T₁ = 0.8 min

T₂ = 0.2 min

V₁ = 60 m/min

V₂ = 120 m/min

Now, as we know that Taylor's tool life equation -

VTⁿ = k

where V = speed in m/min

           T = time in min

            n = Index

            k = constant

Now,

V₁T₁ⁿ = V₂T₂ⁿ

⇒60 (0.8)ⁿ = 120(0.2)ⁿ

⇒ (0.8)ⁿ = 2(0.2)ⁿ

⇒ ([tex]\frac{0.8}{0.2}[/tex] )ⁿ = 2

⇒4ⁿ = 2

Taking log both side , we get

⇒n log(4) = log(2)

⇒n = [tex]\frac{log(2)}{log(4)}[/tex] = 0.5

Now,

As given , T = 0.4 min

We know,

VTⁿ = V₁T₁ⁿ

⇒V (0.4)ⁿ = 60(0.8)ⁿ

⇒V = 60([tex]\frac{0.8}{0.4}[/tex] )ⁿ

⇒V = 60(2)ⁿ

⇒V = 60([tex]2^{0.5}[/tex])

⇒V = 84.85 m/min

∴ The value of the cutting speed = 84.85 m/min

a.)

As we know ,

V = π×d×N

Let d = 100 mm = 0.1 m

⇒ 84.85 = π×0.1×N

⇒ N = [tex]\frac{84.85}{0.1\pi } = 270.08[/tex] rpm

∴ The value of the spindle speed = 270.08 rpm

b.)

As we know,

P = F×V

⇒P = 1×[tex]\frac{84.85}{60} = 1.414[/tex] W per unit force

∴ The value of the Power for the unit force = 1.414 W

c.)

As given - The friction between tool and workpiece varies 0.25-0.35 during the process.

⇒[tex]u_{max}[/tex] = 0.35

  [tex]u_{min}[/tex] = 0.25

d.)

Rate of maximum force , [tex]F_{max}[/tex] = [tex]u_{max}[/tex] × Normal force

Rate of minimum force , [tex]F_{min}[/tex] = [tex]u_{min}[/tex] × Normal force  

∴ we get

[tex]\frac{F_{max} }{F_{min} } = \frac{u_{max} }{u_{min} } = \frac{0.35}{0.25}[/tex] = 1.4

∴ we get

The rate of maximum force to minimum force = 1.4

Answer:

winter viscosity grades

Explanation:

The “W”/winter viscosity grades describe the oil's viscosity under cold temperature engine starting conditions. There's a Low Temperature Cranking Viscosity which sets a viscosity requirement at various low temperatures to ensure that the oil isn't too thick so that the starter motor can't crank the engine over.

Answer: C... Specialization

Explanation:

Increases as Complete the sentence. As division of labor increases, specialization.

The procedure by which the placenta and fetus depart the uterus is called labor. Vaginal delivery (via the birth canal) and cesarean delivery (surgery) are the two possible methods of delivery.

In order for the fetus to pass through the birth canal, the cervix must first open (dilate) and thin (efface) during a series of ongoing, progressive contractions of the uterus called labor.

The Fair Labor Standards Act (FLSA) specifies requirements for minimum wage, overtime compensation, recordkeeping, and youth employment that are applicable to workers in the private sector and in federal, state, and municipal governments.

Typically, two weeks before or after the anticipated birth date, labor begins. Nobody, however, is entirely sure what starts labor.

Therefore, Increases as Complete the sentence. As division of labor increases, specialization.
