What is the mechanical advantage of a lever with an effort alarm of 12 feet and a resistance arm of 3 feet?

The mechanical advantage of a lever is determined by the ratio of the effort arm to the resistance arm. In this case, the mechanical advantage would be 12 feet (effort arm) divided by 3 feet (resistance arm), resulting in a mechanical advantage of 4.


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.


Which lever would have more mechanical advantage?

A longer lever would typically have more mechanical advantage than a shorter lever. Mechanical advantage is calculated by dividing the length of the effort arm by the length of the resistance arm; therefore, the longer the effort arm, the greater the mechanical advantage.


What is the mechanical advantage of a first-class lever in which the fulcrum is 10 inches from the resistance and 40 inches from the effort?

answer is 4


How is mechanical advantage calculated for levers?

The mechanical advantage of a lever is calculated by dividing the length of the lever arm on the effort side by the length of the lever arm on the resistance side. The formula for mechanical advantage is MA = Length of effort arm / Length of resistance arm. It represents the factor by which a lever multiplies the force applied to it.

What is the mechanical advantage of a lever with a resistance arm of 1.5 feet and an effort arm of three feet?

The mechanical advantage of a lever is calculated by dividing the effort arm length by the resistance arm length. In this case, the mechanical advantage would be 2, as 3 feet (effort arm) divided by 1.5 feet (resistance arm) equals 2.


How is the mechanical advantage of a lever determined?

The mechanical advantage of a lever is determined by dividing the length of the lever on the effort side (distance from the fulcrum to the point where the effort is applied) by the length on the resistance side (distance from the fulcrum to the point where the resistance is located). This ratio provides insight into how much force is gained or lost when using the lever.


What is the mechanical advantage of a first class lever in which the fulcrum is 10 inches from the resistance and 40 inches from the effort?

The mechanical advantage of a first class lever is calculated as the ratio of the effort arm to the resistance arm. In this case, the effort arm is 40 inches and the resistance arm is 10 inches, giving a mechanical advantage of 4:1. This means that the lever can multiply the input force by a factor of 4.


When is a mechanical advantage increased by a 1st class lever?

A mechanical advantage is increased in a 1st class lever when the distance from the fulcrum to the point of effort is greater than the distance from the fulcrum to the point of resistance. This allows for less effort to be exerted to move a greater resistance.


What are the fulcrum resistance and effort?

A fulcrum is the fixed point around which a lever pivots. The resistance is the force opposing the movement of the lever, while the effort is the force applied to move the lever. The position of the fulcrum relative to the resistance and effort forces determines the mechanical advantage of the lever system.


What does the machanical advantage of a first-class lever depend apon?

The mechanical advantage of a first-class lever depends on the relative distances between the effort force, the fulcrum, and the resistance force. The mechanical advantage is calculated as the ratio of the distance from the fulcrum to the effort force to the distance from the fulcrum to the resistance force.


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.
