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.
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.
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.
answer is 4
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.

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.
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.
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.
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.
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.
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.
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.
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.
