What is the formula for moment arm?

The formula for moment arm is distance between the point of rotation and the line of action of the force. Mathematically, it can be represented as the cross product of the position vector and the force vector.


The product of force and lever-arm distance in producing rotation is?

In a lever, the product of effort and effort arm is called Moment of effort and product of load and load arm is called Moment of load. In general case, as asked in the question, "The Product of force and lever-arm distance is called Moment of Force"the Moment of Force isn't correct its {Torque}


What is the moment arm of resistance?

The moment arm of resistance refers to the perpendicular distance from the line of action of a resisting force to the axis of rotation. It helps determine the torque generated by the resistance force on a lever or rotating object. A longer moment arm increases the torque generated by the resistance force.


When A force of 5 newton is acting parallel to the moment arm of 10 cm . so what is torque?

In order for a force to produce a torque, either all of it, or a part of it (component) must act perpendicular to the moment arm. If, as in your case, all of the force is parallel to the moment arm then the force can not produce a torque. So the answer is; the torque is zero.


What is the difference between moment arm and lever arm in the context of mechanical systems?

In mechanical systems, the moment arm and lever arm both refer to the distance between the axis of rotation and the point where a force is applied. The moment arm specifically relates to the perpendicular distance, while the lever arm is the actual distance along the line of action of the force.


When the line of action of a force intersects the center of mass of an object can that force produce a torque about the objects center of mass?

No, if the line of action of a force passes through the center of mass of an object, the force will not produce a torque about the object's center of mass because there is no moment arm to create a lever arm for rotation. Torque is the result of the force acting at a distance from the axis of rotation.


SI units for moment arm is?

The SI unit for moment arm is meters (m). It represents the perpendicular distance between the point of rotation and the line of action of a force. It is a crucial parameter in calculating torque or moment in physics and engineering.


How do you calculate the moment arm in a mechanical system?

To calculate the moment arm in a mechanical system, you measure the perpendicular distance from the pivot point to the line of action of the force applied. This distance is important in determining the torque or rotational force in the system.


When does a force not cause a moment about a given point?

A force does not cause a moment about a given point if the line of action of the force passes through that point, resulting in the moment arm being zero. In such cases, the force will only result in a translational motion, but not rotational motion.


What do you get when you multiply effort force by the effort arm distance?

In physics, moment is a combination of a physical quantity, like force, and a distance. For example, a moment of force is the product of of a force and its distance from an axis, which causes rotation about the axis.


When A force of 5N is acting parallel to the moment arm of 10Cm .so what is torque?

50N/Ccm


Where should a force be applied to a lever arm to produce the most torque?

A force should be applied at the end of the lever arm farthest from the fulcrum to produce the most torque. This maximizes the lever arm length, resulting in a greater moment arm for the force and thus higher torque.
