Which motion does a couple produce?
It has a resultant moment but does not have resultant force.
What is An example of case when resultant force is zero but torque is not zero?
[object Object]
What is the difference between torque and couple?
The turning effect of a force is called torque or moment of the force. SI unit of torque is Newton-Metre. T = FL i.e Torque = Force x Moment arm A couple is formed by two unlike parallel forces of the same magnitude but not along the same line.
Is resultant a vector quantity?
The resultant of two vectors cannot be a scalar quantity.
What is the resultant of 1230 ms South and 1450 ms North?
The resultant is 220 North.
Give an example of a case when the resultant force is zero but resultant torque is not zero?
A couple.
What is an example when resultant force is zero but resultant torque is not zero?
A couple: 2 parallel forces equal in magnitude, but opposite in direction separated by a distance.
Which motion does a couple produce?
It has a resultant moment but does not have resultant force.
Why is the moment of a couple a free vector?
A couple is a mechanical term defined as a system of forces that produces a resultant moment but not a resultant force. The moment caused by a couple is different than the moment caused by a single force. The moment of a force is dependent upon a reference point (i.e. if this reference point changes the moment also changes), therefore it is a fixed (or bound) vector. However, the moment (or torque) of a couple is independent of a reference point. In other words any reference point will give the same torque. This fact is proven in Varignon's Second Moment Thereom. Since the moment (or torque) of a couple is independent of a reference point, it may be represented as a free vector. This means that the vector may be freely moved in space.

French word for torque?
torque -> le couple
How do you know if the system is in equlibrium?
A system is in equilibrium if: 1. The resultant force on it is zero. 2. The resultant torque on it is zero. Note that for a system which is a point object, only condition 1 is necessary for the system to be in equilibrium.
What is the difference between torque and couple?
The turning effect of a force is called torque or moment of the force. SI unit of torque is Newton-Metre. T = FL i.e Torque = Force x Moment arm A couple is formed by two unlike parallel forces of the same magnitude but not along the same line.
What 2 things does the moment of a force depend on?
What two factors must be known in order to calculate the moment of a force? Torque = Force * distance Torque and distance must be perpendicular to each other If not you must determine the portion of the torque that is perpendicular.
How does the equilibrant force compare with the resulltant force?
The resultant is a trigonometric function, usually using the Law of Cosines in two dimensional solution by vector resolution, of two or more known forces while equilibrant is equal in magnitude to the resultant, it is in the opposite direction because it balances the resultant.Therefore, the equilibrant is the negative of the resultant.
Is resultant a vector quantity?
The resultant of two vectors cannot be a scalar quantity.
What is inertia torque?
Inertia torque an imaginary torque, which when applied upon a rigid body, brings it in an equilibrium position. Its magnitude is equal to accelerating couple, but opposite in direction.T1 = -IαwhereI = mass moment of inertia of body andα = angular acceleration
