Why is the line of action of a force important?
Line of action, From Wikipedia, the free encyclopedia By knowing the line of action of a force, we can be considered direction or rotation of an object. To understand the mechanism of the effect of force, it is necessary to know its action line, so it is important. The significance of it can be determined from the definition of the line of action.
What is the line of action in physics?
Line of action. It is the line through the point at which the force is applied in the same direction as the vector F→. The concept is essential, for instance, for understanding the net effect of multiple forces applied to a body. As an example, if two forces of equal magnitude act upon a rigid body along the same line of action...
What are lines of force in physics?
Line of force. The concept of lines of force was introduced into physics in the 1830s by the English scientist Michael Faraday, who considered magnetic and electric effects in the region around a magnet or electric charge as a property of the region rather than an effect taking place at a distance from a cause.
What is the difference between force vector and line of force?
Unlike the force vector which begins at the point where the force is applied and extends according to the magnitude of the force, the line of force goes through the point and extends indefinitely in both directions. It is a geometric construct. If the lines are not identical you will have a torque applied.
How do you find the line of action?
We can find the line of action by taking moments about a point. Do by means of an example. Example 2: F1 = 2 i + j N is applied at A(2, 0). F2 = 6 i + 3 j N is applied at O(0, 0).
What is the line of action in moments?
A moment causes a rotation about a point or axis. If the moment is to be taken about a point due to a force F, then in order for a moment to develop, the line of action cannot pass through that point. If the line of action does go through that point, the moment is zero because the magnitude of the moment arm is zero.
What is line of action of resultant?
The line of action of the resultant of two like parallel forces shifts by one-third of the distance between the forces when the two forces are interchanged.
What is the line of action in torque?
The line of action of a force is an imaginary line of indefinite length drawn along the direction of the force. The moment arm of a force is the perpendicular distance from the line of action of a force to the axis of rotation.
What is resultant of a force?
The resultant force is the single force that has the same effect as two or more forces acting together. Two forces in the same direction. Two forces that act in the same direction produce a resultant force that is larger than either individual force.
What does a course of action mean?
1. Any sequence of activities that an individual or unit may follow. 2. A possible plan open to an individual or commander that would accomplish, or is related to the accomplishment of the mission.
When line of action of two or more forces are on same line they are?
Collinear forces: The forces, whose lines of action lie on the same line, are known as collinear forces. When two or more forces act on a body, they are called to form a system of forces.
When the line of action of force acting on a body co inside with the axis of a body is known as?
Explanation: The moment is the product of the force applied to the body and the perpendicular distance of the point of action of the force to the axis about which the body is being rotated. That is the moment is the cross product of the force and the distance between the axis and the point of action. 6.
What is moment in force?
The turning effect of force is known as moment of force. It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn. the S.I unit is newton metre (Nm). Physics.

What does it mean when torque is zero?
If Torque = 0 ; that means either Force(perpendicular) = 0 , or Radius = 0; Case I : If Force(perpendicular) = 0; that means Acceleration(perpendicular) will be equal to 0; therefore Velocity(perpendicular) won't change . This implies Angular Momentum (L=mvr) won't change. Angular Momentum remains constant.
What is moment arm of force?
Moment arm (r) – the moment arm is the perpendicular distance from line of action of the force to the axis of rotation. Direction of rotation – this is the direction that the applied force will cause the joint to rotate.
Homework Statement
what is meant by line of action of force? how to understand this concept? suppose i kick a ball and the ball moves in east. then can i say the line of action of force is along the movement of the ball, that is towards the east. i find this concept of line of action of force in toque. could u please help me to understand, revered members?

You could think of the line of action as a sort of axis along which the force is applied.

When were lines of force invented?
The concept of lines of force was introduced into physics in the 1830s by the English scientist Michael Faraday, who considered magnetic and electric effects in the region around a magnet or electric charge as a property of the region rather than an effect taking place at a distance from a cause. The electric lines of force ...
What are the lines of force that represent the field of a positive electric charge in space?
The electric lines of force that represent the field of a positive electric charge in space consist of a family of straight lines radiating uniformly in all directions from the charge where they originate. A second positive charge placed in the field would travel radially away from the first charge.
What is a magnetic field line called?
In the case of a magnetic field, since no isolated unit pole has ever been discovered, the field lines are called lines of force only in the sense that a small magnet is forced to align itself in the direction of these field lines.
