An effort arm is the part of a lever where the input force is applied. This force is used to overcome the resistance in order to move the load. The length of the effort arm influences the mechanical advantage of the lever system.
The longer the effort arm of a lever, the less effort force is needed to lift a load. This is because a longer effort arm increases the leverage, allowing a small effort force to lift a greater load. Conversely, a shorter effort arm requires a greater effort force to lift the same load.
A lever with a longer effort arm and a shorter resistance arm would have more mechanical advantage. In this case, if you increase the effort arm to 7 inches while keeping the resistance arm at 3 inches, the mechanical advantage would increase. This is because a longer effort arm allows for less force to be applied to overcome a greater resistance.
The formula to calculate effort force in a lever is Effort Force = Load Force x Load Arm Length / Effort Arm Length. This formula takes into account the load force being lifted, the length of the load arm, and the length of the effort arm to determine the amount of effort force needed to lift the load.
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.
The distance between the effort and the fulcrum is known as the effort arm. It determines the amount of force required to move an object when using a lever. A longer effort arm requires less force to move the object, while a shorter effort arm requires more force.

The longer the effort arm of a lever, the less effort force is needed to lift a load. This is because a longer effort arm increases the leverage, allowing a small effort force to lift a greater load. Conversely, a shorter effort arm requires a greater effort force to lift the same load.
THE PRODUCT OF EFFORT AND EFFORT ARM IS CALLED MOMENT OF EFFORT.

This formula takes into account the load force being lifted, the length of the load arm, and the length of the effort arm to determine the amount of effort force needed to lift the load.
4Explanationfor a lever,effort * effort arm = load *load armso by re arranging above equation,load/effort = effort arm/load armNow, as load/effort is called mechanical advantage so,mechanical advantage = effort arm/load armAs total length of rod is 2 m out of which 1.6 m is effort arm so remaining 0.4 m would be load arm. thus on putting values in the above equation, we getmechanical advantage = 1.6/0.4 = 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 16cm (effort arm) divided by 2cm (resistance arm), resulting in a mechanical advantage of 8.
effort arm
The distance between the effort and the fulcrum is known as the effort arm. It determines the amount of force required to move an object when using a lever. A longer effort arm requires less force to move the object, while a shorter effort arm requires more 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.
