A helical compression spring has a spring constant of 38.525 N/mm and a free length of 190 mm. The force (N) required to compress the spring to a length of 125 mm is most nearly:
A. 2,500 B. 1,500 C. 4,800 D. 6,500

Answer:

Option D is correct.

The market for textbooks has a shortage. There will be an upward pressure on price, which will cause quantity demanded to fall and quantity supplied to rise.

Explanation:

The complete question is attached to this solution.

Note that

- The quantity demanded is the negative sloping line in colour blue indicating that the quantity demanded increases as the price of the commodity (textbook) falls and the quantity demanded rises as the price of the textbook falls.

- The quantity supplied is the positive sloping line in colour red/orange indicating that the quantity supplied decreases as the price of the commodity (textbook) falls and the quantity supplied increases as the price of the textbook falls.

The quantity demanded and the quantity supplied balance each other and cross path at a point called the equilibrium point.

The price at this point is called the equilibrium price and the quantity at this point is the equilibrium quantity.

For this question, the equilibrium price = $150 and the equilibrium quantity that matches quantity demanded with quantity supplied = 500.

At prices greater than the equilibrium price, the quantity demanded falls and the quantity supplied increases, hence, there is a surplus of the commodity (textbook) as the quantity of textbooks supplied is way more than the quantity demanded and there is more than required textbooks.

At prices lower than the equilibrium price, the quantity demanded increases and the quantity supplied reduces, hence, there is a shortage of commodity (textbook) as all of the goods supplied are totally bought with extra demand remaining.

When there is a surplus or shortage, the market forces that are responsible for price fixing and quantity demanded work together to take the market back to equilibrium.

So, when the price is higher than equilibrium price and there is a surplus, the market works to reduce the price of the commodity so that quantity demanded can rise and quantity supplied can fall to counter this surplus.

When the price is lower than equilibrium price and there is a shortage, the market works to increase the price of the commodity so that quantity demanded can fall and quantity supplied can rise to counter this shortage.

The price of the textbook in the question, $125, is lower than the equilibrium price, $150, hence, there will be a shortage of textbooks because the quantity demanded, at this price, is higher than the quantity that will be supplied.

So, there is then a pressure on the price to rise back so that the quantity demanded reduces and the quantity supplied increases.

To complete the algorithm, the missing steps 3 and 4 should iterate through the list until the end is reached. This can be achieved with a loop. Here is a possible solution:

Step 3: while position is less than or equal to n, repeat steps 4 and 5.
Step 4: increase the value of position by 1.
Step 5: if the value of the element at index position is greater than 100, increase the value of count by 1.
This revised algorithm will go through each element in the list and count the number of elements with a value greater than 100. The loop in steps 3-5 ensures that all elements are considered.
It is worth noting that there are other ways to implement this algorithm, such as using a for loop or a foreach loop, but the core logic remains the same: iterate through the list and count the elements that meet a certain condition.To complete the algorithm that counts the number of elements in a list with values greater than 100, you can replace steps 3 and 4 with the following:
Step 3: Increase the value of position by 1.
Step 4: If position is less than or equal to n, go back to step 2.
So, the complete algorithm is as follows:
1. Set count to 0 and position to 1.
2. If the value of the element at index position is greater than 100, increase the value of count by 1.
3. Increase the value of position by 1.
4. If position is less than or equal to n, go back to step 2.

Answer:

A

Explanation:

The mineral that makes up this cement is calcite, which is a mineral made up of calcium carbonate (CaCO3).

Calcite is an extremely strong mineral, and when scratched with a steel nail it exhibits the same hardness as the grains of cement. Calcite is a sedimentary rock composed of crystals of calcite, which are formed from the recrystallization of lime mud and limestone. Calcite has an unusual property of effervescing in acid, which is why it is used in cement and mortar. When mixed with other minerals, such as quartz, it produces a strong binding material that is highly resistant to weathering.

The hardness of calcite is due to its crystal structure, which makes it difficult to scratch or break. It is one of the most abundant minerals on Earth and is found in both sedimentary and metamorphic rocks. Thanks to its hardness and durability, calcite is an ideal material for use in cement and mortar.

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Rho=76Mpa

Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

Matter can exist in different phases, namely solid, liquid, and gas. Let's compare and contrast these phases in terms of particle arrangement, motion, temperature, and phase changes. In a solid, particles are closely packed in a regular pattern, forming a fixed shape. The particles vibrate in their positions but don't move freely. Solid's temperature remains constant during a phase change.

Phase changes occur due to heat gained or lost. When heat is added, solids can melt into liquids (fusion) and liquids can vaporize into gases (vaporization). These processes require energy input to break intermolecular forces. When heat is removed, gases can condense into liquids (condensation) and liquids can freeze into solids (solidification). These processes release energy as heat is removed and intermolecular forces strengthen.

A heating/cooling curve illustrates the relationship between heat added/removed and temperature changes during phase changes. It typically shows temperature on the y-axis and time on the x-axis. The curve has flat portions where phase changes occur, indicating a constant temperature during those changes. I hope this helps! Let me know if you have any further questions.

The maximum compression imparted to the spring is 1.61 ft

The potential energy of the box at the top of the plate can be calculated using the formula:

U = mgh

U = (5 lb) x (32.2 ft/s^2) x (5 ft) = 806.5 ft-lb

This potential energy is converted into kinetic energy as the box falls. The kinetic energy can be calculated using the formula:

K = (1/2)mv^2

K = (1/2)(5 lb)(v^2)

The kinetic energy is then converted into elastic potential energy stored in the spring as it compresses. The amount of energy stored in the spring can be calculated using the formula:

E = (1/2)kx^2

(1/2)(5 lb)(v^2) = (1/2)(k)(x^2)

Simplifying, we get:

v^2 = kx^2/5

The velocity just before the box hits the plate can be found using conservation of energy:

K = U

(1/2)(5 lb)(v^2) = 806.5 ft-lb

v^2 = 161.3 ft^2/s^2

Now we can plug this value into the equation we derived earlier:

161.3 ft^2/s^2 = kx^2/5

x^2 = (161.3 ft^2/s^2)(5)/k

x^2 = 806.5/k

x = sqrt(806.5/k)

Plugging in the value for k, we get:

x = sqrt(806.5/(301 lb/ft))

x = 1.61 ft
