Answer:
stink
Explanation:
on the same scale for stress, the tensile true stress-true strain curve is higher than the engineeringstress-engineering strain curve. Explain whether this condition also holds for a compression test.
Answer:
The condition does not hold for a compression test
Explanation:
For a compression test the engineering stress - strain curve is higher than the actual stress-strain curve and this is because the force needed in compression is higher than the force needed during Tension. The higher the force in compression leads to increase in the area therefore for the same scale of stress the there is more stress on the Engineering curve making it higher than the actual curve.
Hence the condition of : on the same scale for stress, the tensile true stress-true strain curve is higher than the engineering stress-engineering strain curve. does not hold for compression test

What is "Engineering"?
Assume that 50,000 yd3 of the soil from a local borrow pit in Rhode Island, with a water content of 13% and dry unit weight of 87 pcf, is to be delivered to a construction site for some repairs of highway in I-95. By the time it reaches the site, the water content is 9%. It will be compacted to a minimum of 90% of the modified Proctor maximum dry density. Determine the total amount of water (in pounds), that must be added to the soil to increase the moisture content to the optimum level. Assume a Gs
Answer:3000 yd3
Explanation:
so i got the 50000 divided it by 100 times that by 13 and got 4500 yd3
so now the soil is at 9 so i need to get the 4 percent back up so i yet again got 50000 yd3 and divided by 100 and times it by 9 to get 1500 yd3 to then minus my 1500 and 4500 yd3 and got 3000 yd3 i hope it is right.
Consider one-dimensional heat conduction through a large plane wall with no heat generation that is perfectly insulated on one side and is subjected to convection and radiation on the other side. It is claimed that under steady conditions, the temperature in a plane wall must be uniform (the same everywhere). Is this claim reasonable
Answer:
YES, this claim reasonable
Explanation:
the temperature in a plane wall is uniform since no heat is penetrating into the large plane wall and therefore, there is no heat transfer from the wall under steady conditions,
This condition will be met only when there are no temperature differences within the wall and the the outer surface temperature of the wall is equal to the temperature of its surrounding.
Therefore, Yes, this claim is reasonable
The bottom of a pan is made of a 4-mm-thick aluminum layer. In order to increase the rate of heat transfer through the bottom of the pan, a design was proposed for the bottom that consists of a 3-mm-thick copper layer sandwiched between two 2-mm-thick aluminum layers. Assume a perfect contact between the layers. Will the new design conduct heat better
Answer:
Yes, the new product will not conduct heat better
Explanation:
The bottom of the former product is made up of a 4mm thick aluminum layer
The new design is made up of two 2mm thick aluminum layer with a 3mm thick copper layer sandwiched in between.
These two materials are great conductors of heat.
As for copper, if one end is heated , the other ends rapidly reaches the same temperature, Copper is known as the best conductor of heat, that is, allows quick heat transfer. This ability of copper makes it highly used in applications where quick heat transfer is important, like the saucepans where rapid heat transfer is required.
As for aluminum, it is also a great heat conductor and twice as good as copper.
But the heat conductivity of copper is greater than aluminum and this will allow a faster heat transfer between the layers.

Which statement correctly describes why the electric pole has bent?
A.) Tensile stress acting on the pole caused it to bend.
В.) Compressive stress acting on the pole caused it to bend
С.) The force acting on the pole exceeded its yield strength.
D.) The force acting on the pole exceeded its compressive strength.
Answer:
С.) The force acting on the pole exceeded its yield strength.
Explanation:
Answer:
The correct answer is C. The force acting on the pole exceeded its yield strength.
Explanation:
I got it right on the Plato test.
(25%) A well-insulated compressor operating at steady state takes in air at 70 oF and 15 psi, with a volumetric flow rate of 500 ft3 /min, and compresses it to 60 psi. The power input to the compressor is 80 horsepower. Kinetic and potential energy changes from the inlet to exit can be neglected. Determine the exit temperature, in oR.

2 Describe the four major disciplines of engineering and identify problems or projects that an engineer in each discipline might encounter. Chemical engineering Civil engineering . Electrical engineering Mechanical engineering
Answer:
Chemical engineering
Uses chemical processes to find new ways to produce goods. Making antibiotics, pesticides, safe clothes, and foods.
· Civil engineering
Builds structures to try and make them efficient. Makes a tornado-proof house, explosion-proof bunker, or easily navigable subway system.
· Electrical engineering
Develops the electrical components for things. Game systems, keyboards, projectors, or hard drives.
· Mechanical engineering
Mechanical engineers work with things with mechanical processes and moving parts. Drills, wheels, elevators, or cranes.
