Both A and B are correct. Front-wheel drive cars frequently have press-fit cartridge-style wheel bearings installed in the knuckles.

On many cars, both the front and the rear wheel bearings are typically sealed inside bolt-on hub assemblies. Uneven weight distribution over the contact patch may result from underinflated tires starting to lose their correct form. Both tread edges may begin to deteriorate noticeably more quickly than other parts of the tire if they are subjected to increased weight. The wheelset's dynamic unbalance will increase, increasing the lateral force, derailment coefficient, and wheel unloading ratio as well as decreasing the hunting critical speed and the quality of the vertical ride. Dynamic imbalance can also be brought on by a damaged tire or wheel, however it typically results from manufacturing variances. Dynamic imbalance, of course, degrades ride quality and tends to hasten the deterioration of tire and steering and suspension system parts.

a. Best Critical Region (BCR): The critical region that maximizes the power of a statistical test.

b. Uniformly Most Powerful Test (UMPT): A statistical test with the highest power among all possible tests for a given significance level.

c. Pivotal Quantity (PQ): A function of sample data and an unknown parameter with a known distribution independent of the parameter.

d. Randomized Test: A statistical test where the decision to accept or reject the null hypothesis is determined randomly.

e. Sequential Probability Ratio Test (SPRT): A method for sequential decision-making based on accumulating evidence from a sequence of observations, useful for efficient binary decision-making.

a. The best critical region (BCR) refers to the region in the sample space where the null hypothesis is rejected, resulting in the most favorable trade-off between the probabilities of type I and type II errors. It is the critical region that maximizes the power of the statistical test.

b. The uniformly most powerful test (UMPT) is a type of statistical test that possesses the most power among all possible tests for a given significance level. It is designed to detect the alternative hypothesis with the highest probability, making it the most powerful test in a statistical hypothesis testing framework.

c. A pivotal quantity (PQ) is a function of the sample data and an unknown parameter that has a known distribution that does not depend on the parameter itself. Pivotal quantities are useful in statistical inference as they allow for the construction of confidence intervals and hypothesis tests that are distribution-free or have known distributions.

d. A randomized test is a type of statistical test where the decision to accept or reject the null hypothesis is determined by a random mechanism. It involves using a randomization procedure to assign observations to different treatment groups or to determine the critical region. Randomized tests have the advantage of controlling the type I error rate and can be useful in situations where traditional fixed-sample tests may not be appropriate.

e. The Sequential Probability Ratio Test (SPRT) is a statistical method used for making sequential decisions based on accumulating evidence from a sequence of observations. It is commonly used in quality control and decision-making processes where data is collected sequentially. The SPRT allows for early termination of the test if a decision can be reached with sufficient confidence based on the available data, leading to efficient and timely decision-making. It is particularly useful when testing hypotheses or making binary decisions in a sequential manner, reducing the number of observations required compared to traditional fixed-sample tests.

AASHTO assumes a deceleration value in calculating stopping sight distance (SSD) of B. 11.2 ft/s^2. This doesn't take any road defects into account.

(a) Molar flux of A at the surface of the sphere:Molar flux (NA) is defined as the number of moles of A that passes through a unit area per unit time. In radial flow, the molar flux of A is:NA = -DAB(∂CA/∂r) = -DAB(CA/rt)Where, rt = radius of the sphere and CA = concentration of A.Since the mole fraction of A at the surface of the sphere is XAO, then we can express the molar flow rate of A at the surface of the sphere as:NA0 = NA|rt=ro = -DAB(CAO/ro)(XAO/1 - XAO)(b) If the distance at which the mole fraction was considered to be effectively zero were located at 100ro from the centre of the sphere instead of 10ro from the centre, then there would be a large change in the molar flux of A.This is because the concentration gradient between the centre of the sphere and 100ro from the centre of the sphere would be much steeper than between the centre of the sphere and 10ro from the centre. Therefore, there would be a larger concentration gradient driving the diffusion of A, which would result in a larger molar flux of A.(c) If one considers the case of 1-dimensional diffusion across a film rather than the case of radial diffusion from a sphere, then a tenfold increase in the length of the diffusion path would result in a roughly tenfold decrease in the molar flux obtained in the 1-dimensional system. This is because the molar flux is directly proportional to the concentration gradient, and a tenfold increase in the length of the diffusion path would result in a tenfold decrease in the concentration gradient.In terms of the relative change in molar flux produced by a tenfold increase in the diffusion path, there is a greater relative change in molar flux produced by a tenfold increase in the diffusion path in the case of 1-dimensional diffusion across a film than in the case of radial diffusion from a sphere. This is because the concentration gradient is much steeper in the case of radial diffusion from a sphere, which means that the molar flux is less affected by a change in the length of the diffusion path.

Answer:

It is economical

Explanation:

Given data for determining

cost of product = £5 per kg

cost of solvent = £20 per /kg

additional solvent makeup = 10 kg/d

current loss of product = 0.7 kg/h

anticipated recovery of product = 80%

additional service ( utility cost ) = negligible

Determine if it is economical to install the recovery system

cost of product = £5 per kg

cost of solvent = £20 per /kg

additional solvent required = 10 kg / d

cost of additional solvent in a day  = £200 / day  ( £20 per kg * 10 kg / d )

product lost = 0.7 kg/h

product recovered = 0.7 * 80% = 0.56 kg/h

therefore product recovered in a day = 0.56 * 24 = 13.44 kg / day

Next :

calculate income generated from product recovery

13.44 kg/day *  £20 /kg =  £268.88 / day

Determine if it is economical

Income - cost

= £268.88 - £200

=  £68.88  ( hence it is economical )

Answer:

D. All the above

Explanation:

A is correct. The theory of formation of concrete is based on this phenomenon of formation of voids because, a coarse aggregate aggregate on its own, contain voids. When a fine aggregate like sand is added, it occupies these voids. Further, when finely powdered cement is added to the mixture, it further occupies the voids between the sand particles.

B is correct. The bulking of sand should be taken into account when volumetric proportioning of the aggregates is adopted. Otherwise, less quantity of concrete per bag of cement will be produced, which naturally will increase the cost of concrete. This is because sand particles when left on their own, do not pack properly near each other due to sand buckling, leaving too many void spaces between the sand particles.

C is correct . The dry sand and the sand completely flooded with water have practically the same volume. This is due to the bulking of sand. When water is added to the sand, up to complete flooding, the sand particles pack near each other and the amount of bulking of sand is decreased. The addition of the volume of water, leads to a decrease in the volume of the sand due to the extra voids. These cancels out to practically leave the dry sand and the flooded sand with the same volume.
