# Multibody Mechanics

This web text is a reference for all topics in the mechanics of multibody systems. A format similar to that of an encyclopedia has been adopted to clearly take advantage of web style referencing and encourage other authors to add new topics or complete existing ones where they are lacking.
A topic is deemed complete when it includes the following elements:
* an overview of the method or operation outlining its application.
* a complete analytical description (and derivation where appropriate).
* example of computational implementation (in a MATLAB and Octave compatible m-file).

# Multibody Mechanics/Angular Velocity

Angular velocity is a vector which describes the rotation rate of a reference frame relative to another reference frame.
Typically the Greek letter $\omega$ (omega) is used exclusively to represent angular velocities (and many authors also use $\Omega$). In this text the angular velocity of frame "B" relative to "A" is denoted as
The angular velocity vector is defined such that any vector ${\vec {\zeta }}$ which is fixed (constant) in the local frame "B" (reference frame) has its time derivative in another frame "A" expressed with a cross product as
This relationship is not difficult to prove, however doing so is of little practical use and is deferred to the end of this discussion. It is useful to note that since vectors can be expressed as linear combinations of basis vectors, this relationship finds its way into of the expression for a the derivative of a general vector (including angular velocity itself).
Angular velocity is not

# Past LSAT Explained/Main Idea(RC)

Main Idea (Reading Comprehension) This global question is a perennial favorite RC question. It is important you remember not only what the author is saying but why he is saying. The author is leading you to a certain point. All the LSAT passages are well-written (if convoluted) and scholar piece of writing. Though hidden under the loads of difficult ideas and facts, the main idea itself is pretty evident and unequivocal (otherwise the LSAC will have a hard time defending the answer to 100,000 test takers).
# Past LSAT Explained/February 2007 LSAT

The February 2007 LSAT On most test forms, the experimental section appeared in Section 1 or Section 3. The difficulty of the test was equal to that of other recent exams.

## Analytical Reasoning

22 questions
The February games section as similar in difficulty to the December 2006 games section.
* Game 1 Order with out column-5 questions (easy-medium)
* Game 2 In-Out groups-6 questions (medium)
* Game 3 Order with grouping-6 questions (easy-medium)
* Game 4 Order with two tiers and distribution-5 questions (difficult)

## Logical Reasoning

25 and 26 questions The 26-question section as harder than the 25-question section. The 26-question section had a run of difficult questions in the middle of the section that was balanced by some easier questions sprinkled in at the end. The 25-question section had a steadier progression of difficulty. The overall distribution of questions on the test was consistent with that of other recent exams.

## Reading Comprehension

27 questions
Somewhat easier than the RC sections that appeared on the June and October 2006 exams and more in keeping with the December RC section.
* Passage 1 Humanities (easy)
* Passage 2 Natural Science (medium-difficult)
* Passage 3 Law (medium)
* Passage 4 Social Science (medium-difficult)
# Past LSAT Explained/Global(RC)

Reading Comprehension Global Questions require that you have read the entire passage in order to answer the question. The question tests your skill in seeing the forest not just the tree. Often the Global questions are easier because there are much more information to work with.
# Past LSAT Explained/Logical Reasoning
## Question Types
### Point at Issue

the main point at issue is an issue in dispute is are committed to disagreeing about expresses a point of agreement

### Assumption

Tests to Use
# Faslification Test
Negate the choice and see if the argument stands. If it collapses, the choice is among the assumptions that the argument depends.
# Main Point Test
If the choice is the conclusion or main point of the passage, it is necessarily not the assumption.
# Past LSAT Explained/Methodology

THINK LIKE THE TESTMAKERS The LSAT is a test of your way of thinking. It tests how well you think like the testmakers. Once you start to think like them, you can be thought as having the LSAT mind. Your preparation of the LSAT should therefore focus on learning to this way of thinking.

## Logical Reasoning

This PrepTest explanation for Logical Reasoning sections follows a methodology called IRAC(pronounced EYE-rack) which stands for: Identify, Read, Analyze, and Choose. It is a step by step methodology for tackling LSAT questions.
Identify
The IRAC starts with quickly scanning the question. Most LSAT questions start with a brief passage or statement followed by a question. It is important to figure out exactly what the question is looking for. You may decide to skip the question if you are low on time or the question seems too difficult. You can choose to guess random.
Read
You need to move to the beginning of the passage and quickly and accurately work the passage. Underline, paraphrase and engage with the passage. Using symbols to mark the passage. Do not overanalyze or bring outside information or knowledge but stick to what's provided.
Analyze
Use your LSAT analytical skill. Apply the right analysis required by the question. You are not given credit for doing something else. Once you are done with analyzing the passage, move to each response.
Choose

## Reading Comprehension

This PrepTest explanation for Reading Comprehension sections follows a methodology called BRIEF (you are essentially briefing the passage) which stands for: Break, Read, Internalize, Eliminate, Find. It is a step by step methodology for tackling LSAT questions.
Break
Go to the questions and figure out the key terms and words. You are essentially breaking the question. When you read, pay a special attention to those words and relationship.
Read
Scan quickly and visualize a chart in your brain.
Internalize
Digest what you read.
Eliminate
Do not look for the right answer. Look for the wrong one first.
Find
Mark your answer sheet and move on.

## Analytical Reasoning

This PrepTest explanation for Analytical Reasoning sections follows a methodology called CASES which stands for: Chart, Analyze, S, Eliminate, Select. It is a step by step methodology for tackling LSAT questions.

# Past LSAT Explained/Method of Argument(LR)
## Type

It is mentioned as one possible reason for adopting a policy for which the author suggests an additional reason.
Taking the highest score among multiple LSAT scores may relieve test anxiety for many law school applicants. As critics point out, however, it also encourages students to take the test multiple times, incurring unnecessary costs and time for test preparation. Yet, since the ABA statistics show that the highest score is the better predictor for law school performance than the average score, law schools should change their policy to consider the highest test score rather than the average.

## Type

It is a claim that the author attempts to refute with counterarguments. The admissions officer argues that the average score of all LSAT taken is the best measure of the applicant's ability. This is clearly nonsense. Suppose we have one college senior who received a 160 and then a 172. Compare this person with another who received 166 twice. Can we say their abilities are equal? How about someone who got a 172 the first time and 160 the second time due to illness? People who have one score are usually do not take it again because they are satified with the score and often they believe it is the highest possible score.

## Type

It is a hypothesis for which the teacher offers additional evidence.

## Type

It is cited as an insufficient reason for elimination.

## Type

It is cited as an objection that has been raised to the position the author is supporting.

## Type

If attending an event, would be a good idea to download the software in advance to your laptop in order to avoid the download during the labs. The copyrighted software is not distributable so the volunteers will not be able to give you all the required software components. But organizers may have set up a proxy server to speed up downloads or provide at least the free software.

## Windows 7 64 bit

This book covers Windows 7 64 bit as host even if all operating systems that can run VirtualBox 64-bit can be used. 64 bits are mandatory since Oracle 12c for Linux 32-bit is not available.

## VirtualBox

This book uses VirtualBox as many Oracle specialists consider it as a mature and free virtualization solution, fully compatible with Oracle Software: https://www.virtualbox.org/. The VirtualBox version 4.3.26 and older versions from 4.2.12 up to 4.2.18 have been tested successfully with OEL6 and Oracle 12c. The latest successfully tested VirtualBox version is 5.0.8
A few virtualbox versions (4.3.14 to 22 if I remember well ) had serious problems on Windows. EL 6.4 to 6.7 have been tried without problems.

Appendix
This chapter explains how to separate Swing applications into a more maintainable triad of components: the domain model, the view of the user interface, and the controller that oversees these. A minimal class structure is shown below.
The main application class is the controller: it creates a model object (which is Observable), and a view object (which is an Observer of the model). The controller adds the view as an observer of the model.
When the model changes, it calls setChanged and then notifyObservers. This means that the model can react to user input.
The controller doesn't touch the view (apart from instantiating it and giving it the model).
The view has access to the model, including to change it.

The ear is the part of the body that lets people hear. Some animals, like people and most vertebrates, have two ears, but some animals do not hear through ears. Spiders have small hairs on their legs that they can hear with. The ear works by directing sound to the inner ear. These vibrations are sent to the brain by a network of nerves.

### .M3P Parameter

The .M3P Parameter file format stores data from the Formulas, Lighting, Postprocess, and Main windows. It does not store any image data.
.M3P is a binary format, not human-readable.

#### History

Since .M3P is a binary format that stores parameter data only, file sizes are very small. The small file size makes it possible for Mandelbulb3D to automatically save a history of changes to disk. Inside the Mandelbulb3D installation folder is a subfolder named History. When the Calculate 3D button is pressed, Mandelbulb3D stores the current scene parameters to an .M3P file in the History folder. History files are organized in subfolders by date, and files are named according to the current time.

### M3F Formula File

.M3F is the native format for Mandelbulb3D formula definitions. A formula is the mathematical "DNA" of a fractal. It determines what parameters exist and how users can interact with them.
The Mandelbulb3D default installation includes hundreds of formulas, found in the M3Formulas folder. New formulas are being developed by volunteers. Fractalforums.com, the birthplace of the Mandelbulb, is still the place to go for new formulas.
