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.
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.
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.
Why MA of third class lever is always less than one?
In a third-class lever, the effort arm is always shorter than the resistance arm. This mechanical advantage formula is calculated as resistance arm length divided by effort arm length. Since the effort arm is shorter than the resistance arm, this division always results in a value less than one, indicating that the force needed at the effort arm is larger than the force exerted at the resistance arm to lift a load.

What is the MA of a lever if the resistance arm is 20cm and the effort arm is 100cm?
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 MA would be 5 (100cm/20cm).
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 a effort arm?
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.
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.
4 If you were unable to move an object using an effort arm that was 5 feet long would increasing the length of the effort arm help?
Yes, increasing the length of the effort arm would make it easier to move the object. The longer the effort arm, the more leverage you have to overcome resistance. By increasing the length of the effort arm, you can apply less force to move the object.
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 lever arm ratio?
Divide the length of the force arm by the length of the resistance arm.
