torque = twisting force. The torque of a propeller aircraft engine (single engine) tends to rotate the aircraft in the opposite direction as the propeller rotation, causing the aircraft to turn in that direction.

∙ 13y agoTorque is the ability of an engine or motor to rotate a shaft. Torque is also a measure of the rotational force placed on a bolt, nut, or screw.
A powerful mid-sized car produces about 200 foot-pounds of torque. If your drive shaft had a one-foot bar sticking out the side, it would take 200 pounds of force to stop the engine.
When tightening nuts and bolts in the engine, we want all the bolts to be exactly right. Otherwise gaskets will blow out and metal parts will crack. A torque wrench tells us exactly how much force we are applying to the bolt. Larger bolts will have torque specified in foot pounds (e.g. 65 f-p) while very small ones will be specified in inch pounds (e.g. 10 i-p). Metric bolts can be specified in metric units (e.g. 7 m-kg).
Torque wrenches range in price from just a few dollars up to several hundred. A needle style is less accurate but perfectly usable for as little as $15. A nice KD tools model is more than $150.

How do i calculate the torque of an engine?
Torque is defined as force multiplied by the distance, from the axis of rotation, at which such as force is applied.In the case of an engine, I believe the torque would have to be measured.
What term is best defined as the resistance to motion between two bodies in contact?
Torque, I think.
Why does a bar magnet placed in S-N direction turn towards N-S direction when torque acting on it is zero?
If the bar magnet turned then there was a torque acting upon it. Torque is defined as a turning force or moment.
What is meant by torque in ac machines?
'Torque' applies to any motor, not just to a.c. motors. It is a turning moment, defined as distance multiplied by the force acting at right-angles to the shaft.
How do you compare the units of work and kinetic energy?
Work and kinetic energy are defined as scalar energy and have the same units joules. dW=F.dr = (dP/dt) dr=dP(dr/dt) = dPv = vdP= mvdv W = F.r = mv^2/2. Physics has defined scalar energy but has no definition for vector energy mcV. Torque which is T= Fxr should be recognized as vector energy but it is defined as "Torque". This is another example of Physics not appreciating that the Universe is made of Quaternions, a Scalar part and a Vector part. E= FR = -F.R + FxR where the scalar energy has been defined as work (F.R) and the vector energy is defined as Torque FxR. Kinetic energy is a transformation of work in terms of mass and velocity versus force and distance. The vector energy is not called energy. See link: http://en.wikipedia.org/wiki/Torque
What are torques?
Torque is a force that is applied to a lever. (Imagine a rachet. As you tighten a bolt, you push on the handle, which is essentially a lever. This lever exerts torque on the bolt, causing it to spin) Torque is defined as T = r cross F, or just R X F. Basically, if you multiply the force by the distance of the force from the central point on the object you are trying to rotate, you have torque.
What is the torque speed characteristic?
the ratio of the relative speed of stator magnetic field with the speed of rotor, to the speed of rotor is defined as slip. where as in torque slip characteristic is the graph between the speed of the rotor and the torque experienced on the rotor. in the case of induction motor, the torque decreases with the increase in the rotors speed. while in the case of sychronous motor, its different (you check out, because i just forgot about it!! keep smiling!
Why does a screwdriver allow you to turn a screw you couldn't turn by hand?
A screwdriver allows you to exert more torque on a screw. Torque is defined as the product of the force exerted and the distance from the center of rotation. Torque is essentially a rotational force. It is simple to increase torque, simply increase the distance from the center that the force is being applied, and there is greater torque without increasing your effort. The handle is made to be wide, so that a greater torque can be exerted. It is also much easier to grip a screwdriver than it is to grip a screw. That also plays a factor.
Is it possible to calculate the torque acting on rigid body without specifying the axis?
Not at all possible. Torque defined as the moment of the force about a point or an axis of rotation. Torque tau vector = radius vector x Force vector. Radius is to be measured only from a given point or given axis. Hence axis in very important

Why torque is zero when force is applied to point that passes through pivot point?
Torque is defined as the product of the distance from the pivot point, times a force, times an angle function. If any of the three factors is zero, the product is zero. In this case, the distance from the pivot point.
Why the force needed to undo the bolt is smaller when a spanner with a longer handle is used?
Basically, the longer the handle, the less force is needed to apply a certain torque. This is defined by the equation t=fd where t= torque, f= force, and d= distance in a radial fashion.
