The three PRINCIPAL Stresses in the Shell are the Circumferential or Hoop Stress, the LONGITUDINAL Stress, and the Radial Stress.

If the Cylinder walls are thin and the ratio of the thickness to the Internal diameter is less than about then it can be assumed that the hoop and longitudinal stresses are constant across the thickness. It MAY also be assumed that the radial stress is small and can be neglected. In point of fact it MUST have a value equal to the pressure on the inside SURFACE and zero at the outside surface. These assumptions are within the bounds of reasonable

Probability theory and statistics, the moment-generating function of a real-valued random variable is an alternative specification of its probability distribution. ... There are PARTICULARLY simple results for the moment-generating FUNCTIONS of distributions defined by the WEIGHTED sums of random variables.

Mathematical expectation, also known as the expected VALUE, is the summation or integration of a possible values from a random variable. It is also known as the product of the PROBABILITY of an event occurring, DENOTED P(x), and the value corresponding with the actual OBSERVED occurrence of the event.

Estimating in Statistics

Anna is an animal lover and volunteers at a local animal shelter in her town. She wants to make a proposition to the city council to create a dog park in the town. She wants to gather some data about the opinions of the town. Because she can't survey the entire town, she will need to collect data from a few people and make an estimation. An estimation is the tool that is used in mathematics to make inferences about populations from data.

In this LESSON, you will learn about two types of estimation: point and interval estimation. Let's begin with point estimation as we follow Anna's story.

Point Estimation

Anna surveys 100 random people out of her town about building a dog park. This is known as a sample. A sample is a part of a population used to describe the whole group. Anna will use the data that she gathers from this sample to describe the population of the town. The data Anna gathers will be statistics.

A statistic is the characteristics of a sample used to infer information about the population. For example, Anna may include questions on her survey such as age and number of pets. If the mean age for her sample is 32, then 32 is a sample statistic. She might infer that the average age of the people in town is also 32.

A point estimation is a type of estimation that uses a single value, a sample statistic, to infer information about the population. Point estimation can be a sample statistic. The sample mean of age for the sample, 32, can be used as a point estimation.

Point estimation is a single value that can be inferred as a population PARAMETER. Let's discuss populations, parameters, and their relationship to point and interval estimations.

Interval Estimation

After Anna collected her data from the survey, she can now draw inferences from her sample statistics about the population. A population is all members of a specified group. In this CASE, the population is literally the population of a town. However, a population can mean many things. For example, if you are doing research about college students, then your population would be all college students. If your research is about high school athletes, then your population would be all high school athletes. It's mostly up to the researcher to define the population.

Once sample information is gathered, the researcher can make inferences about the population, known as a parameter. A parameter is the characteristics used to describe a population. You can use a sample statistic to develop population parameters. For example, Anna found that of the 100 people she surveyed, each household owns an average of two pets. This is a sample statistic. However, Anna can also use this statistic to infer that everyone in the population also owns an average of two pets; at this point it is considered a population parameter. If we were estimating from a single value, such as the average of two pets, then we could say that this population parameter was a point estimation.

However, what about the people that own more than two pets or no pets? Can 100 people really show us the characteristics of an entire town? This is where interval estimation comes in handy. Interval estimation is the range of NUMBERS in which a population parameter lies considering margin of error. Because there is a certain level of uncertainty, an interval estimate gives a range, rather than a single value, of the population parameters.

A NULL HYPOTHESIS is a type of hypothesis used in STATISTICS that proposes that no statistical significance EXISTS in a SET of given observations.

This SOUNDS like a trick QUESTION. Unit vectors are by DEFINITION MAGNITUDE of 1 each.

P.S. Additional insight one can GENERATE is that the 2 vectors are 90 deg apart

Since pressure = FORCE /AREA(in metres)
you can USE this formula to get the answer....
but you have to KNOW the side of BRICK on which it lie on ground to find area...

Hey frnd....

HOPE THIS HELP YOU ☺☺❤❤❤

S(h) = K*h^2

The STRENGTH of a beam is PROPORTIONAL to the square of the THICKNESS means the strength is equal to the thickness squared, which is h squared (as its thickness equals h) MULTIPLIED by the proportionality constant k.

N(L) = k/L^2.

When "is proportional to" appears there will will always be a multiplication of a proportionality constant .

"Inverse square of L" means 1/L^2.

⭐Actually welcome to the concept of the THERMODYNAMICS...

⭐Basically we know that ..ACCORDING to the first law of thermodynamics we get ..


⭐Delta U = dW + q

⭐thus we know that ... W = -P.dV

⭐thus we know that .. P = FA

⭐also ..work done = F.dx

⭐thus ..W = P . A . ( l-x)

⭐so after SOLVING we this ...

Spillways are structures constructed to provide safe release of flood waters from a dam to a downstream are, normally the river on which the dam has been constructed. EVERY reservoir has a certain capacity to store WATER. If the reservoir is full and flood waters enter the same, the reservoir level will go up and may eventually result in over-topping of the dam. To avoid this situation, the flood has to be passed to the downstream and this is done by providing a spillway which draws water from the top of the reservoir. A spillway can be a part of the dam or separate from it.

Spillways can be controlled or UNCONTROLLED. A controlled spillway is provided with gates which can be raised or lowered. Controlled spillways have certain advantages as will be clear from the DISCUSSION that follows. When a reservoir is full, its water level will be the same as the crest level of the spillway.

This is the normal reservoir level. If a flood enters the reservoir at this time, the water level will start going up and simultaneously water will start flowing out through the spillway. The rise in water level in the reservoir will continue for some time and so will the discharge over the spillway. After reaching a maximum, the reservoir level will come down and eventually come back to the normal reservoir level.

1. AVAILABILITY OF EARTH MATERIALS

Earth is readily available in most parts of the world close to possible DAM sites. Now a days the knowledge of soil mechanics has further enhanced the chances to make unstable earth dam as stable.

2. EASY HANDLING OF EARTH

Earth can be excavated by hand, TRANSPORTED in baskets and compacted with cattles walking over it. In suitable situation, earth can be handled and MOVED with latest machinery.

3. FOUNDATION CONDITION

Earth dams are SUITED to the sites where a masonry dam cannot be used for structural reasons. These dams can be constructed even on compressible foundations. The intensity of foundation stress due to earth is less than that due to solid masonry. The horizontal water pressure on the dams is distributed over greater area because of greater base width and hence, the danger of sliding on a weak foundation is minimized. The greater width of dam foundation also minimizes the leakage through the foundation beneath the dam.

4. COST OF CONSTRUCTION

The most important advantage of an earth dam compared to masonry dam, is its lesser cost. It has been observed that the total cost of an earth dam, is roughly one-half of a concrete dam.

Canal Fall. Thus, a canal fall or drop is an irrigation structure CONSTRUCTED across a canal to lower down its bed level to maintain the DESIGNED slope when there is a CHANGE of ground level to maintain the designed slope when there is change of ground level. This falling water at the fall has some surplus energy

The net force and the acceleration on the falling skydiver is upward. An upward net force on a DOWNWARD falling object would cause that object to slow down. The skydiver THUS slows down. As the speed DECREASES, the AMOUNT of AIR resistance also decreases until once more the skydiver reaches a terminal velocity.
