4.1.1 Let L be the length of the cube, then the cube's volume is L³. According to Archimedes' principle, the weight of the cube is equal to the weight of the oil displaced by the submerged half. The volume of oil displaced is L² × L/2, so its mass is (0.78 × 1000 kg/m³) × (L² × L/2) = 390L²/2. The weight of the cube is 2 × 9.8 = 19.6 N.

Therefore, we have:

19.6 = (390L³)/2L = (19.6 × 2 × 2)/(390) = 0.2 m

Therefore, the dimensions of the cube are 0.2 m × 0.2 m × 0.2 m.4.1.2 Let D be the depth that the 3 kg cube of wood will sink to. Then the weight of the cube is equal to the weight of the seawater displaced by the submerged cube. The volume of seawater displaced is D² × 0.2, so its weight is 1025 × D² × 0.2 N. The weight of the 3 kg cube is 3 × 9.8 = 29.4 N. Therefore, we have:

29.4 = 1025 × D² × 0.2D² = 29.4/(205 × 0.2) = 0.07183D = 0.2685 m

Therefore, the 3 kg cube of wood will sink to a depth of 0.2685 m.4.1.3

Let m be the mass that needs to be added to the 6 kg block to make it sink in seawater. Then the weight of the block plus the added mass is equal to the weight of the seawater displaced by the submerged block. The volume of seawater displaced is 0.2 × 0.2 × 0.6 = 0.024 m³, so its weight is 1025 × 0.024 × 9.8 = 24.198 N. The weight of the 6 kg block is 6 × 9.8 = 58.8 N. Therefore, we have:

58.8 + m = 24.198m = 24.198 - 58.8 = -34.602 kg

Therefore, a mass of 34.602 kg must be added to the 6 kg block to make it sink in seawater.

A large tower is to be supported by a series of steel wires. It is estimated that the load on each wire will be 11,100 N.

Determine the minimum required wire radius assuming a factor of safety of 3 and a yield strength of 1500 MPa.

answer in mm please

Answer:

the minimum required wire radius is 5.3166 mm

Explanation:

Given that;

Load F = 11100N

N = 3

∝y = 1500 MPa

∝workmg = ∝y / N = 1500 / 3 = 500 MPa

now stress of Wire:

∝w = F/A

500 × 10⁶ = 11100 / A

A = 22.2 × 10⁻⁶ m²

so

(π/4)d² = A

(π/4)d² = 22.2 × 10⁻⁶

d² = 2.8265 × 10⁻⁵

d = 5.3165 7 × 10⁻³ m³

now we convert to mm(millimeters)

d = 5.3166 mm

Therefore the minimum required wire radius is 5.3166 mm

The probability calculations for the given scenarios can be performed using the normal distribution with a mean of 1200 and a standard deviation of 80.

To calculate the probabilities, we can use the standard normal distribution table or statistical software such as R or Python.

a. To find the probability of a selected engine having a capacity greater than 1260, we calculate the z-score as (1260 - 1200) / 80 = 0.75. Using the z-score table or software, we find the probability associated with a z-score of 0.75.

b. For the probability of a selected engine having a capacity greater than 950, we calculate the z-score as (950 - 1200) / 80 = -3.125. Again, using the z-score table or software, we find the probability associated with a z-score of -3.125.

c. To determine the probability of a capacity of 1240 or less, we calculate the z-score for 1240 as (1240 - 1200) / 80 = 0.5. We find the probability associated with a z-score of 0.5.

d. The probability of a selected engine having a capacity less than 1130 can be calculated by finding the z-score for 1130 as (1130 - 1200) / 80 = -0.875. We find the probability associated with a z-score of -0.875.

e. For the probability of a capacity between 1100 and 1150, we calculate the z-scores for both values as (1100 - 1200) / 80 = -1.25 and (1150 - 1200) / 80 = -0.625. Then, we find the probabilities associated with these z-scores and calculate the difference between them to obtain the desired probability.

Answer: the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Explanation:

Given that;

Weight of soil r = 118 lb/ft³

stress parameter C = 250 lb/ft²

φ total = 29°

depth Z = 12 ft

The shear strength on a horizontal plane at a depth of 12ft

ζ = C + δtanφ

where δ = normal stress

normal stress δ = r × z = 118 × 12 = 1416

so

ζ = C + δtanφ

ζ = 250 + 1416(tan29°)

ζ = 250 + 1416(tan29°)

ζ = 250 + 784.9016

ζ = 1034.9015 lb/ft²

Therefore the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Centrifugal force is the force exerted on an object moving in a circular path and directed outward from the center. In order to determine the centrifugal force in pound-force of a centrifuge carrying 50mL of blood, we will need to use the formula for centripetal force:

Centrifugal force = (mass x acceleration)/radius

Here's how to solve the problem:

First, we need to determine the mass of the blood being carried by the centrifuge. We know the volume of blood (50 mL) and the density of blood (0.994 g/mL), so we can use the formula:

mass = volume x density

mass = 50 mL x 0.994 g/mL

mass = 49.7 g

Next, we need to convert the given units to SI units (meters and seconds):

Centripetal acceleration = 64 ft/s^2
1 ft = 0.3048 m
Centripetal acceleration = 64 ft/s^2 x 0.3048 m/ft = 19.5072 m/s^2

Rotational speed = 345 rpm
1 rpm = 1/60 s
Rotational speed = 345 rpm x 1/60 s = 5.75 s^-1

Now we can use the formula to calculate centrifugal force:

Centrifugal force = (mass x acceleration)/radius

The radius of the centrifuge is half the diameter (3.5 inches or 0.0889 meters):

Centrifugal force = (49.7 g x 19.5072 m/s^2)/0.0889 m

Centrifugal force = 10,879.52 N

Finally, we need to convert Newtons to pound-force:

1 N = 0.22481 lb-f
Centrifugal force = 10,879.52 N x 0.22481 lb-f/N

Centrifugal force = 2,442.69 lb-f

Therefore, the centrifugal force in pound-force is 2,442.69 lb-f.

The logistic regression model is used to predict the financial condition of banks based on two financial ratios.

The paragraph describes a logistic regression model used to predict the financial condition of banks based on two financial ratios. The "Condition" column records the expert judgment of a bank's financial condition, categorized as either weak or strong.

The logistic regression model estimates the equation associating the bank's financial condition with the two predictors, namely the ratio of total loans and leases to total assets and the ratio of total expenses to total assets.

The estimated equation can be expressed in three formats: i. Logit as a function of the predictors, ii. Odds as a function of the predictors, and iii. Probability as a function of the predictors. For Bank A and Bank B with given ratios, the logistic regression model is used to estimate the logit, odds, and probability of being financially weak for each bank.

The classification of each bank (Strong or Weak) is determined based on the estimated probability. The bank with a higher probability of being financially weak is classified as weak, while the other is classified as strong.
