moment = rF r = perpendicular distance from the force... Is there any shortcut to do this question ? or just keep on trial and error until get the correct ans ??haruspex said:What can you say about moments?
No, I mean what is the relationship between the moments of the forces and torque in the diagram about C and the moment of the equivalent force?werson tan said:moment = rF r = perpendicular distance from the force...

The line of action is an imaginary line that represents the direction and magnitude of a force. It is often depicted as an arrow pointing in the direction of the force and labeled with its magnitude.
In this context, "r" represents the position vector of a point on the line of action. It indicates the distance and direction of the point from a fixed reference point, usually the origin.
It is important because it allows us to determine the exact location where the force is acting on an object. This information is crucial in analyzing the effects of the force on the object's motion and stability.
The point of intersection is calculated by finding the point where the position vector "r" is perpendicular to the line of action. This can be done by using vector algebra and trigonometry.
Yes, this concept is used in various fields such as engineering, physics, and biomechanics. For example, in engineering, it is used to calculate the torque exerted by a force on a rotating object. In biomechanics, it is used to analyze the forces acting on the human body during movement.
