The total hours that are necessary to reduce carbon dioxide level to at least 325 ppm are 4 hours.

He added some images of tools that came into wide use, such as adzes and axes and even armor. Miguel left out one tool, however, that was highly important to the civilization’s progress. What might have been that tool, and why is it important?

A.
hammer, invaluable for building homes

B.
drinking vessel, essential for carrying water

C.

The heavy plough was an important tool in the Iron Age and Middle Ages because it allowed farmers to cultivate more land and produce more food. This led to a population increase and a more prosperous society.

The other tools mentioned are also important, but they are not as essential as the heavy plough.

The hammer is useful for building homes, but it is not as important as the plough for food production. The drinking vessel is essential for carrying water, but it is not as important as the plough for advancing food production.

A large retirement community wants to host a grand birthday party for its residents who recently

that 25 new centenarians will be the guests of honor at the party, so they decide to prepare some
interesting facts about this group's age. They start brainstorming, and one of the organizers says,
"Hey, the standard deviation of their ages would be an interesting fact."

Which of the following best represents the standard deviation for the ages of the new centenarians?

Answers

The ideal response for the age standard deviation would be zero.

Why is there a standard deviation?

A standard deviation (or σ) is a measure of how distributed the data is in reference to the mean. When the standard deviation is low, the data are concentrated around the mean, and when it is large, the data are widely dispersed.

They invited 25 persons who recently turned 100 years old, so the majority of attendees will be between the ages of 100 and 102. There is extremely little likelihood that anyone will be older than 102.

Since the majority of the data are centered at 100, the standard deviation will be zero or very close to it.

A 4KJ of energy is supplied to a machine used for lifting a mass. The force required is 800N. If the machine has an efficiency of 60℅,to what height will it lift the mass?​

Answers

The height at which the mass will be lifted is; 3 meters

How to utilize efficiency of a machine?

Formula for efficiency is;

η = useful output energy/input energy

We are given

η = 60% = 0.6

Input energy = 4 KJ = 4000 J

Thus;

0.6 = useful output energy/4000

useful output energy = 0.6 * 4000

useful output energy = 2400 J

Work done in lifting mass(useful output energy) = force * distance moved

Useful output energy = 800 * h

where h is height to lift mass

Thus;

800h = 2400

h = 2400/800

The solid cylindrical bar shown is subjected to a bending force F = 55kN, an axial load P = 8 kN, and a torsional load T = 30 kN-mm. The bar is made of AISI 1060 CD steel (Sy = 280 MPa, Sut = 330 MPa). Find the factor of safety based on Maximum Distortion Energy Theory.

Answers

The factor of Safety by Maximum Distortion Energy Theory is given as: N = 6.04

What is Maximum Distortion Energy Theory?

According to this idea, failure by yielding happens when the distortion energy per unit volume in a condition of combined stress equals that associated with yielding in a basic tension test at any location in the body.

What is the calculation for the above value?

Note that we are given the following:

A solid Steel bar subjected to a bending force of F = 55kN

Torsional load T = 30 kN-mm; and

Yield Strength (sy) = 280Mpa

Sut = 330 Mpa

The formula for Normal Stress is given as:

[tex]\alpha _{x}[/tex] = [UP/πd²] + [ (32* f * L)/πd³]

= [(4 * 8 * 10³)/π * (0.02)²] + [(32 * 55 *10³ * 0.1)/ π * (0.02)³]

= 25.46 + 7.003

[tex]\alpha _{x}[/tex]= 32.5 Mpa

Tyz = (16T)/πd³

= (16 * 30)/ π * (0.02)³

= 19.098

Tyz = 19.098

Following from the above, sate of stress, we have:

α₁ = αₓ = 32.46 Mpa; and

α₂ = Tyz = 19.098 Mpa;

α₃ = -Tyz = -p19.098 Mpa;

Utilizing the formula given by the Maximum Distortion Energy Theory:

α₁² + α₂² + α₃² - (α₁α₂ + α₂α₃ + α₃α₁)

= Sy²/N²

→ 32.46² + 19.098² + 19.098² - ( 32.46* 19.098 - 19.098² -32.46 *  19.098)

= 280/N²
