# Topic: Torque

###### In the News (Fri 17 May 13)

 torque. The Columbia Encyclopedia, Sixth Edition. 2001-05 The magnitude of the torque acting on a body is equal to the product of the force acting on the body and the distance from its point of application to the axis around which the body is free to rotate. The net torque acting on a body is always equal to the product of the body’s moment of inertia about its axis of rotation and its observed angular acceleration. Units of torque are units of force multiplied by units of distance, e.g., newton-meters, dyne-centimeters, and foot-pounds (or pound-feet). www.bartleby.com /65/to/torque.html   (244 words)

 A.K.O. Inc. - What is torque? Simple leverage is the same as torque and both are measured in terms of force and distance (distance is the length of the lever, force is the amount of pulling or pushing applied at the end of the lever). A torque wrench is used in conjunction with a threaded fastener for the single purpose of controlling the clamping ability of the fastener. Since the torque applied to the head of the fastener is directly proportional, or nearly so, to the load applied, it is possible to measure bolt stress by means of a torque wrench. www.akotorque.com /html/wit.html   (680 words)

 Torque - Wikipedia, the free encyclopedia The SI units for Torque are newton meters although centinewton meters (cN·m), foot-pounds force (ft·lbf), inch pounds (lbf·in) and inch ounces (ozf·in) are also frequently used expressions of torque. Torque has dimensions of force times distance and the SI units of torque are stated as "newton-metres". Torque is part of the basic specification of an engine: the power output of an engine is expressed as its torque multiplied by its rotational speed. en.wikipedia.org /wiki/Torque   (1360 words)

 Torque The torque effect on the fuselage is a direct result of the work/resistance of the main rotor. Compensation for torque in the single main rotor helicopter is accomplished by means of a variable pitch anti-torque rotor (tail rotor) located on the end of a tail boom extension at the rear of the fuselage. Since torque effect varies during flight when power changes are made, it is necessary to vary the thrust of the tail rotor. www.dynamicflight.com /aerodynamics/torque   (698 words)

 Horsepower vs torque The DOHC puts out 133 ft-lb of ground-pounding torque, but I've seen some older Neons that are leaking torque and you have to avoid driving behind them because the torque, once leaked, is slippery. 2nd gear output torque at the redline is still greater than 3rd gear output torque at any engine speed, so you wind her out as far as she'll go before you shift to 3rd. Increasing the torque of an engine at a particular RPM is the same as increasing the power output at the same RPM. www.allpar.com /eek/hp-vs-torque.html   (1872 words)

 All about torque The torque, specified with regard to the axis of rotation, is equal to the magnitude of the component of the force vector lying in the plane perpendicular to the axis, multiplied by the shortest distance between the axis and the direction of the force component. So in short, torque is the combination of force applied at a point with the right angle (perpendicular) distance from that point to the axis of rotation (in our case, this'll be an axle). Now torque stays the same (we like to say "remains constant") all along the shaft so at the big gear (#2) it still has 1 inch-ounce of torque trying to turn it. www.solarbotics.net /bftgu/tutorials_mech_torque.html   (995 words)

 What Is Torque? In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, 'a' being the angle between r and F. The torque you created on the door is smaller than it would have been had you pushed the correct side (away from its hinges). So, it is only the tangential component of the force which affects torque (since it is perpendicular to the line between the point of action of the force and the pivot point). www.physics.uoguelph.ca /tutorials/torque/Q.torque.intro.html   (592 words)

 Torque (Moment) A torque is also a vector quantity and produces a rotation in the same way that a force produces a translation.
