It's the ratio of the distances effort-fulcrum/load-fulcrum.
In a first class lever, as the distance from the fulcrum to the point where the input force is applied increases, the mechanical advantage also increases. This means that the lever becomes more efficient at moving a load with less effort.
answer is 4
Move the focal point of the leaver.
A first-class lever can have a mechanical advantage greater than, equal to, or less than 1, depending on the relative distances between the fulcrum, effort force, and load. It does not inherently have a high mechanical advantage.
Yes, but its Mechanical advantage is usually less than 1
A first-class lever always increases mechanical advantage, as the effort arm is longer than the load arm. The mechanical advantage is determined by the ratio of the lengths of the two arms of the lever.
In a first class lever, the mechanical advantage will be increased when the distance from the fulcrum to the effort force is greater than the distance from the fulcrum to the resistance force. This allows for a smaller input force to lift a larger resistance force.
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 mechanical advantage is increased by a first-class lever when the distance from the fulcrum to the effort force is greater than the distance from the fulcrum to the resistance force. This arrangement allows for the input force to be amplified in order to overcome a larger resistance force.
The advantage of a first class lever is that by using less input force, you get more output force. Teehee!
It depends upon where the fulcrum is, and it can be changed by moving the fulcrum.
