So, the area is h times the average of the lengths of the two vertical edges. dx. We can readily determine that f(x) = 1/x, h = 1/5 (so h/2=1/10), and xj =1+ j/5, 0 ≤ j ≤ 5. Another technique for approximating the value of a definite integral is called Simpson's Rule. Also, how do you calculate the area of a Waterplane?
To obtain the total water-plane area, we can divide the water-plane into 2 parts, apply Simpson's First Rule separately to each partial area, and then add the results to get the total area of water-plane.
Also Know, what are the three types of ship stability? There are three types of equilibrium conditions that can occur, for a floating ship, depending on the relation between the positions of centre of gravity and centre of buoyancy.
Intact Stability of Surface Ships:
- Stable Equilibrium: Study the figure below.
- Neutral Equilibrium:
- Unstable Equilibrium:
Similarly, it is asked, what is mid ordinate rule?
14.1 Mid Ordinate Rule: According to the rule, the base line AB of irregular figure ABCD is divided into a number of equal strips each of breadth s. At the mid point of each strip a vertical line drawn is called the mid ordinate. The area of each strip is approximately equal to s x mid ordinate.
What is fineness coefficient?
The coefficient of fineness of the water-plane area is the ratio of the area of the water-plane to the area of a rectangle having the same length and maximum breadth. A ship 128 metres long has a maximum beam of 20 metres at the waterline, and coefficient of fineness of 0.85.

How stability of ship is calculated?
GM - Metacentric Height: This measurement is calculated by subtracting KG from KM (GM = KM - KG). GM is a measure of the ship's initial stability. BM - Metacentric Radius: The distance between the Center of Buoyancy and the Metacenter. What is Simpson's first rule?
As noted above, the Simpson's First Rule formula requires that we multiply the half-ordinates by a series of constants called Simpson's Multipliers. For 3 ordinates, the Simpson's Multipliers are 1, 4, 1. For 5 ordinates, the Simpson's Multipliers are 1, 4, 2, 4, 1. How do ships float?
With no load onboard, the ship sinks into the water by a certain amount. The amount of water it displaces (shaded area) weighs as much as the ship. The weight of the ship pulling down (red arrow) and the upthrust pushing up (blue arrow) are equal and opposite forces, so the ship floats. What is ship trim?
The trim of a ship is the difference between the forward and aft draft. When the aft draft is greater the vessel is deemed to have a positive trim, and it has a negative trim when the forward draft is the greater. In such a case it is often referred to as being down-by-the-head. How do you calculate stability?
GM - Metacentric Height: This measurement is calculated by subtracting KG from KM (GM = KM - KG). GM is a measure of the ship's initial stability. BM - Metacentric Radius: The distance between the Center of Buoyancy and the Metacenter. What is the formula for the trapezoidal rule?
We write the Trapezoidal Rule formula for n=4 subintervals: T4=Δx2[f(x0)+2f(x1)+2f(x2)+2f(x3)+f(x4)]. f(x4)=f(5)=15. What is the difference between trapezoidal rule and Simpson's rule?
Trapezoidal rule can also be referred to as Trapezium rule. Simpson's Rule can also be referred to as Parabolic Rule. Gives an estimated result. For example, the area of an irregular piece of land obtained by trapezoidal rule is just an approximate value and not the accurate value. What is Simpson's 1/3rd rule?
Simpson's 1/3 rule is an Page 2 07.03.2 Chapter 07.03 extension of Trapezoidal rule where the integrand is approximated by a second order polynomial. xaxaaxf + + = . a and 2 a . Since the above form has 1/3 in its formula, it is called Simpson's 1/3 rule. What is the rule for area?
Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply. Is Simpson's rule the most accurate?
Simpson's Rule. Simpson's rule is a method of numerical integration which is a good deal more accurate than the Trapezoidal rule, and should always be used before you try anything fancier. What is Simpson's rule used for?
Simpson's Rule is a numerical method for approximating the integral of a function between two limits, a and b. It's based on knowing the area under a parabola, or a plane curve. Why do we use the Simpsons 3/8 rule?
Simpson's 3/8 Rule This rule quite more accurate than the standard method, as it uses one more functional value. For 3/8 rule, the composite Simpson's 3/8 rule also exists which is similar to the generalized form. The 3/8 rule is known as Simpson's second rule of integration. How do you calculate the area under a curve?
The area under a curve between two points can be found by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a and x = b, integrate y = f(x) between the limits of a and b. Areas under the x-axis will come out negative and areas above the x-axis will be positive. How do you solve an integral numerically?
Numerical integration methods can generally be described as combining evaluations of the integrand to get an approximation to the integral. The integrand is evaluated at a finite set of points called integration points and a weighted sum of these values is used to approximate the integral. How do you use the mid ordinate rule?
14.1 Mid Ordinate Rule: The area of each strip is approximately equal to s x mid ordinate. Approximate area of the figure ABCD = S(a + b + c + d + e + f) Where S = breadth of each strip. If the figure is divided into a different of strips, then area of the figure = S(a + b + c + d + ………………) What is Simpson rule in surveying?
Simpson's Rule. Statement. It states that, sum of first and last ordinates has to be done. Add twice the sum of remaining odd ordinates and four times the sum of remaining even ordinates. Multiply to this total sum by 1/3rd of the common distance between the ordinates which gives the required area. What is N in trapezoidal rule?
The Trapezoidal Rule formula for n=4 subintervals has the form. T4=Δx2[f(x0)+2f(x1)+2f(x2)+2f(x3)+f(x4)]. How do you calculate area in surveying?
The rule states that if the sum of all the ordinates taken at midpoints of each division multiplied by the length of the base line having the ordinates (9 divided by number of equal parts). In this, base line AB is divided into equal parts and the ordinates are measured in the midpoints of each division. What is Prismoidal formula?
Definition of prismoidal formula. A formula used in the calculation of earthwork quantities. It states that the volume of any prismoid is equal to one-sixth its length multiplied by the sum of the two end-areas plus four times the mid-area.
