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.

What is the resistance arm of the lever?
The resistance arm of a lever is the distance between the fulcrum and the point where the external resistance or load is applied. It is the part of the lever where the output force is exerted to overcome the resistance. The length of the resistance arm affects the mechanical advantage of the lever system.
What is the mechanical advantage of a lever with an effort arm of 16cm an a resistance arm of 2cm?
The mechanical advantage of a lever is calculated by dividing the length of the effort arm by the length of the resistance arm. In this case, the mechanical advantage would be 16cm (effort arm) divided by 2cm (resistance arm), resulting in a mechanical advantage of 8.
Which lever would have more mechanical advantage than one with a resistance arm of 3 riches and an effort arm of 6 inches?
A lever with a resistance arm of 3 inches and an effort arm of 1 inch would have more mechanical advantage as the effort arm is shorter than the resistance arm, making it easier to lift the load.
What is the mechanical advantage of a lever with an effort arm of 12 feet resistance arm of 3 feet?
The mechanical advantage of a lever is calculated by dividing the length of the effort arm by the length of the resistance arm. In this case, the mechanical advantage would be 12 feet (effort arm) divided by 3 feet (resistance arm), which equals a mechanical advantage of 4.
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.
What is the definition of the resistance arm?
The resistance arm is the side of the lever (from the fulcrum to the load) that carries the load.
What is the resistance arm of the lever?
The resistance arm of a lever is the distance between the fulcrum and the point where the external resistance or load is applied. It is the part of the lever where the output force is exerted to overcome the resistance. The length of the resistance arm affects the mechanical advantage of the lever system.

What is lever arm ratio?
Divide the length of the force arm by the length of the resistance arm.
What is the mechanical advantage of a lever with an effort arm of 16cm an a resistance arm of 2cm?

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.
What is the resistance are of a lever?
The resistance arm of a lever is the distance between the fulcrum (pivot point) and the point where the resistance force is applied. It determines the amount of force required to move the resistance, with a longer resistance arm requiring less force to overcome a given resistance.
Can be calculated if the length of the effort arm and the length of the resistance arm given?
Yes, if the lengths of the effort arm and the resistance arm are known, you can calculate the mechanical advantage of a lever. The mechanical advantage is determined by the ratio of the length of the effort arm to the length of the resistance arm. This relationship helps in understanding how much easier it is to lift a load using the lever compared to lifting it directly.
Why you use spring and weight in centrifugal governor?
spring provides a known resistance to the centrifugal force, allowing a mechanical actuation based on RPM to be designed/adjusted with moment arm of weights.
