What is Labor?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.

A square rod is 2 m long and 0.5 m by 0.5 m in cross section. It elongates by 0.5 mm when subject to a tensile load P. The normal longitudinal strain is most nearly:_____
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 tool life decreases from 0.8 min to 0.2 min due to the increase in cutting speed from 60 m/min to 120 m/min in a turning operation.
Compute is the value of the cutting speed at 0.4 min.
a-)Determine the spindle speed in rpm.
b-)Find the required power for the unit force.
c-)The friction between tool and workpiece varies 0.25-0.35 during the process.
d-)Calculate the rate of maximum force to minimum force.
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

An automobile having a mass of 1100 kg initially moves along a level highway at 110 km/h relative to the highway. It then climbs a hill whose crest is 40 m above the level highway and parks at a rest area located there. Use a reference with kinetic and potential energy each equal to zero for the stationary highway before the hill.
Let g = 9.81 m/s2.
For the automobile, determine its change in kinetic energy and its change in potential energy, both in kJ.
Answer:
Change in kinetic energy=-513.652 KJ
Change in potential energy=431.64KJ
Explanation:
We are given that
Mass of an automobile , m=1100 kg
Initial speed, u=110 km/h=[tex]110\times \frac{5}{18}=30.56 m/s[/tex]
Where [tex]1 km/h=5/18 m/s[/tex]
Height , [tex]h_2=40 m[/tex]
[tex]g=9.81 m/s^2[/tex]
Final speed, v=0
Change in kinetic energy,[tex]\Delta K.E=\frac{1}{2}m(v^2-u^2)[/tex]
[tex]\Delta K.E=\frac{1}{2}(1100)(0-(30.56)^2)=-513652.48 J[/tex]
[tex]\Delta K.E=-\frac{513652.48}{1000}=-513.652 KJ[/tex]
Where 1 KJ=1000 J
Change in potential energy,[tex]\Delta P.E=mgh(h_2-h_1)[/tex]
Initially height, h1=0
Using the formula
[tex]\Delta P.E=1100\times 9.81(40-0)[/tex]
[tex]\Delta P.E=431640J[/tex]
[tex]\Delta P.E=431.64KJ[/tex]
Calculate the magnitude of the velocity and the θ angular direction of the block and the bullet together when the 50 g bullet moves to sky at a speed of 600 m/s and hits a sliding 4 kg block with a speed of 12 m/s in a direction with 30o with respect to ground.
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°
in multi-grade oil what is W means?
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.
