What is vector quantity in one word?
a quantity possessing both magnitude and direction, represented by an arrow the direction of which indicates the direction of the quantity and the length of which is proportional to the magnitude. such a quantity with the additional requirement that such quantities obey the parallelogram law of addition.
What is the full form of vector?
The Full form of VECTOR is Viral Emergency Control Tactical Operations and Response, or VECTOR stands for Viral Emergency Control Tactical Operations and Response, or the full name of given abbreviation is Viral Emergency Control Tactical Operations and Response.
How do we use vectors in real life?
Vectors have many real-life applications, including situations involving force or velocity. For example, consider the forces acting on a boat crossing a river. The boat’s motor generates a force in one direction, and the current of the river generates a force in another direction. Both forces are vectors.
What is free vector with example?
For example, a force acting on a rigid body is a localized vector as its effect depends on the line of action of the force. If the value of a vector depends only on its length and direction and is independent of its position in the space, it is called a free vector.
What do you mean by free vector?
Free vectors refers to a vector which is neither a point nor a line, and something that can move freely around the space though it has a fixed magnitude and fixed direction. Unit vector means the direction where you divide the vector by its magnitude.
Why couple is a free vector?
Moments due to couples can be added together using the same rules as adding any vectors. Since the moment of a couple depends only on the distance between the forces, the moment of a couple is a free vector. It can be moved anywhere on the body and have the same external effect on the body.
What is a vector couple?
A couple is a pair of forces, equal in magnitude, oppositely directed, and displaced by perpendicular distance or moment. When d is taken as a vector between the points of action of the forces, then the torque is the cross product of d and F, i.e.
What is couple give example?
A couple consists of two parallel forces that are equal in magnitude, opposite in sense and do not share a line of action. It does not produce any translation, only rotation. For example, the forces that two hands apply to turn a steering wheel are often (or should be) a couple.
What is arm of couple?
If two equal and opposite parallel forces i.e. equal and unlike are acting on a body they don’t have any resultant force. Arm of CoupleThe perpendicular distance d between the lines of action of the two equal and opposite parallel forces is known as arm of couple.
What is the formula of couple?
The forces F and F, which constitute a couple, are acting in opposite direction. From the figure, the formula or equation for Principle of moments is given as, Moment of couple or torque = F Ć LM. The moment becomes zero when the forces acting on the body have the same line of action.
What means couple?
1a : two persons married, engaged, or otherwise romantically paired. b : two persons paired together The people were lined up in couples. 2 : pair, brace needed a couple of bookends. 3 : something that joins or links two things together: such as. a : two equal and opposite forces that act along parallel lines.
What is couple and properties of couple?
A pair of equal and opposite forces with different lines of action is known as a couple. proporties:- A couple produces rotation without translation. Moment of couple is product of magnitude of Forces and the distance between them. Moment of couple is independent of the origin of the forces or reference point.
What are the characteristics of couple?
If there are two forces which are equal and opposite they form a couple. Couple: When two forces of equal magnitude opposite in direction and acting along parallel straight lines, then they are said to form a couple. The perpendicular distance between the two force forming a couple is called the arm of the couple.
What are the uses of couple?
A couple produces rotation without translation. Moment of couple is product of magnitude of Forces and the distance between them. Moment of couple is independent of the origin of the forces or reference point. Uses:- couple is used to rotate the object without giving any translational motion.
What is the Translatory effect of couple?
SOLUTION. Explanation: Two parallel forces equal in magnitude and opposite in direction and separated by a definite distance are said to form a couple. The translatory effect of a couple on the body is zero.
What is Translatory effect?
: motion in which all points of a moving body move uniformly in the same line or direction.
What is difference between couple and torque?
I know the basics of them like Torque is force multiplied by the distance (from the point where there is no rotation like centre of gravity). Couple acts because of two equal and opposite forces acting at a distance. Turning moment is due to rotating force. …
What is restoring couple?
When the two equal or opposite forces are exerted at the two ends of an object, it constitutes a couple. where the Angle of twist at the lower end of the wire is ā , restoring couple is Cā , where C is the torsional rigidity of the wire, and I is the moment of inertia of the disc about the axis of the wire.
