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.
What else can I help you with?
What is nominal moment?
Nominal moment is the entire calculated moment after applying load...
What is meant by moment of inertia in Induction motors?
The second moment of a force is called as moment of inertia.
Difference between vector and scaler quantity?
Oh, dude, it's like this: a vector quantity has both magnitude and direction, like when you're driving and your GPS says to turn left in 500 meters. A scalar quantity, on the other hand, is just the magnitude without any pesky direction involved, like when you tell someone the temperature is 30 degrees Celsius. So, like, vectors are all about where you're going, and scalars are just like, "Eh, who cares about which way?"
Definition of moment of resistance of beams?
thats means load In some countries (Greece for sure) by "moment of resistance" we mean Section Modulus, which is Z=I/y, where I: moment of inertia, y: distance from the neutral axis to the most extreme fibre
Why does a long spanner make it easier to loosen a stuck nut than a short spanner?
This answer is based on simple mechanics. A spanner is a tool which you use to apply a twisting force on a nut. This twisting force is called a Moment. The equation for a moment: moment = force x distance of application As the force given by your arms will not increase just by using a bigger spanner, the size of the moment is directly related to the distance away from the nut the force is applied. So with a short spanner, say 30cm (0.3 metres) long and a typical force from your arm of about 100N (about 10kg) the moment will be: Moment = 100 x 0.3 = 30 Nm Now if a bigger spanner is used, say 50 cm (0.5 metres) long the moment is: Moment = 100 x 0.5 = 50 Nm So you can see if you use a bigger spanner, you are putting a larger twisting force upon the nut, so it it easier to loosen.
Is couple vector or scalar quantity?
A couple is a vector quantity because it has both magnitude (related to the moment of force) and direction (related to the axis of rotation).
Is moment a vector or a scalar?
A vector. Since velocity is a vector, moment, which is mass x velocity, is also a vector.
Take a moment about a point in physic's static means?
In vector format, the moment can be defined as the cross product between the radius vector, r (the vector from point O to the line of action), and the force vector.
Is moment scalar or vector?
Is moment scalar or vector and why? Scalar has magnitude, but no direction. Vector has magitude and direction. Speed is a scalar. The car's speed is 25mi/hr. No direction is mentioned. Velocity is a vector. The car is traveling 25 mi/hr 20º North of East. Velocity is a vector, because it has magnitude and direction Moment has two meanings Moment of inertia = ∑ Mass* raidus^2 This moment measures how difficult it is to rotate an object. This moment is a scalar. Moment can also mean torque. Torque = Force x distance* sinθ (cross product). However torque can be clockwise or counter-clockwise. So torque is a vector.
Is magnetic moment scalar or vector?
Magnetic moment is a vecotr quantity
Why vector is called free vector?
A vector that is not a positional vector (or directly related) is equivalent to another vector of the same magnitude and direction wherever else in space it may be located. Since it is "free" to be located anywhere, it is called a free vector.
Where can one get free vector images?
Free vector images are available from many online sources that store vector images. Fotolia and Vecteezy are just a few examples of free vector image websites.
Are there any free vector logo downloads?
Free vector images are available from several sources, from which a logo can be made. Top free vector sites include Vecteezy, and the free section of Vectorstock.
Is it possible to download Vector clip art online for free?
There are plenty of places in order for one to go to download Vector clip art on the internet for free. It is easy to get the Vector clip art online for free via the website Download Free Vector.
Is a couple a vector quantity?
No, a couple is not a vector quantity. A couple is a pair of forces that are equal in magnitude, opposite in direction, and act along parallel lines. It produces rotational motion without any translation of an object.
Where can one obtain a free flower vector file?
You can find free flower vector files on websites like Vecteezy, Freepik, and Pixabay. These sites offer a variety of vector graphics that are free to download and use for personal or commercial projects.
How can one download a car vector?
You can download a car vector from the following sources: All Free Downloads, For Designer, Free Pik, Vector Island, Vecteezy, Vectors 4 All, Vector Portal, to name a few.
