Torque, moment, or moment of force (see the terminology below) is the tendency of a force to rotate an object about an axis,fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist to an object. Mathematically, torque is defined as the cross product of the position vector of the point where the force is applied (distance vector) and the force vector, which tends to produce rotation.
Loosely speaking, torque is a measure of the turning force on an object such as a bolt or a flywheel. For example, pushing or pulling the handle of a wrench connected to a nut or bolt produces a torque (turning force) that loosens or tightens the nut or bolt.
The symbol for torque is typically , the lowercase Greek letter tau. When it is called moment of force, it is commonly denoted M.
The magnitude of torque depends on three quantities: the force applied, the length of the lever arm connecting the axis to the point of force application, and the angle between the force vector and the lever arm. In symbols:
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Crash Course (also known as Driving Academy) is a 1988 made for television teen film directed by Oz Scott.
Crash Course centers on a group of high schoolers in a driver’s education class; many for the second or third time. The recently divorced teacher, super-passive Larry Pearl, is on thin ice with the football fanatic principal, Principal Paulson, who is being pressured by the district superintendent to raise driver’s education completion rates or lose his coveted football program. With this in mind, Principal Paulson and his assistant, with a secret desire for his job, Abner Frasier, hire an outside driver’s education instructor with a very tough reputation, Edna Savage, aka E.W. Savage, who quickly takes control of the class.
The plot focuses mostly on the students and their interactions with their teachers and each other. In the beginning, Rico is the loner with just a few friends, Chadley is the bookish nerd with few friends who longs to be cool and also longs to be a part of Vanessa’s life who is the young, friendly and attractive girl who had to fake her mother’s signature on her driver’s education permission slip. Kichi is the hip-hop Asian kid who often raps what he has to say and constantly flirts with Maria, the rich foreign girl who thinks that the right-of-way on the roadways always goes to (insert awesomely fake foreign Latino accent) “my father’s limo”. Finally you have stereotypical football meathead J.J., who needs to pass his English exam to keep his eligibility and constantly asks out and gets rejected by Alice, the tomboy whose father owns “Santini & Son” Concrete Company. Alice is portrayed as being the “son” her father wanted.

Plot: Six Months after the IPV Virus converted most of the world's population into ravenous undead flesh-eaters, what we know of the United State and our way of life is gone. Thirteen City-States have risen from the ashes, under the direction of the military organization known as HAVOC. As the war against the undead grinds on, ten soldiers on a clean and sweep mission uncover a stockpile of goods. Before learning the darker truth and triggering an ambush that will push them to their limits.

Plot: Neo, a drifter from the atomic-blasted wastelands, arrives with his klutzy robot sidekick at a factory where slaves labor to fuel the sinister Dark One's Power Station. There, he meets a comely woman who convinces him to help rescue her scientist father, who has invented a device that can break the Dark One's control over the slaves. Gathering a motley crew of allies on the way, Neo and pals travel to the Power Station, where they confront the Dark One's evil servants.

Plot: Dr. Lynn Harper, psychologist, has been called out to the old Ingston Mansion, a dark and mysterious place with a very bad reputation, in order to make an assessment of the sanity of Margaret Ingston, daughter of patriarch Kurt Ingston. She claims to be sane, but she is clearly very disturbed; we can't be certain, although the doctor gives her a clean bill of health. But then Dick Baldwin shows up on the scene, just when Dr. Lynne has been receiving thinly veiled threats from the inhabitants of the house. He's our hero. Three medical doctors have been invited out to the mansion as well, Dr. Timmons, Dr. Phipps and the sleazy Dr. King (Lionel Atwill). One by one the doctors are mysteriously murdered. Dick Baldwin must figure out who is doing the killings, and he must do so before whoever it is can kill his new love interest, Dr. Lynne Harper. But the only one he can trust is Kurt Ingston himself, since Ingston has no legs and can't have perpetrated these murders. Is it sinister Rolf, the butler, or Laurie, the sex crazed and sociopathic chauffeur, or Agor Singh, the Hindu Yogi with his strange ways? And of course, Lynne might be wrong, Margaret may be very insane, and she might be the culprit.

He then explains how a torque is the product of the lever arm and the force perpendicular. The lever arm must be perpendicular to the axis of rotation and the force must be perpendicular to the lever arm. Do you speak another language?

Sexy Science animations for the New Nissan Leaf site. Agency: Critical Mass
my lip gloss froze off
outside the airport
on a hard bench
beside a dingy Santa
i searched every face
what are you?
animated soft tissue
shifting neuropeptides
a social pyromaniac
a plate spinner
and it's smoky around you
i can hardly breathe
i watched your eyes go dark
i saw them look blank
i wasn't there
i saw it in pictures
after the fact
and it's smoky around you
