What is the mechanical advantage of a lever that can lift a 100 N load with an input force of 20 N?

The mechanical advantage is the ratio of the output force to the input force.
MA = output/input (output force divided by the input force)
For the example, 15N/30N gives the MA as 0.5 (one half).

So an AMA (MA) of Two ...
You might have gotten confused, as AMA and MA are often interchanged.
I remember being so confused on such things only to find out that I had the answer the entire time, as I was reading differently worded formulas from multiple physics references ... Just wait until you start measuring Energy in Calories and find out that a calorie is not a calorie, which is also not a Calorie ... It see,s the more 'Educated' humans become, the more 'Common Sense' they lose ... It's not your fault that you can't seem to find the answers, it's all the faulty textbooks ... It is often helpful to narrow down a formula by dropping certain words, such as in this case 'Actual' in AMA, which in turn causes 'AMA' to become 'MA' ... I really hope all of this helps you in your searches ... :)

∙ 15y agoThe mechanical advantage of such a thing is that it will make work easier. This is because it requires very little force to operate.

∙ 13y agoMA = output force / input force
MA = 125N / 25N
MA = 5
No units on this answer because mechanical advantage is a ratio, not a quantity.

Which statement is true about the ideal mechanical advantage of a third-class lever?
mechanical advantage is the output force divided by the input force
Why is the output force of a second-class lever always greater than the input force?
Because of the lever's mechanical advantage.
How is input and output shown on a force diagram?
Input and output are shown on a force diagram by the human being the input force and the load force being the output force. When you divide output force by input force, you get the mechanical advantage of a lever.
What is the mechancial advantage of lever that can lift a 100 N load with an input force of 20 N?
The mechanical advantage of a lever is that it can lift a 100N load with an input of 20N is calculated as is 5. In this case, the effort is divided by the load.
What is a lever with a mechanical advantage greater than one used to do?
Mechanical advantage refers to the ratio of the force produced by a machine to the force applied to it. A lever with a mechanical advantage greater than one is used to increase distance.
Which statement is true about the ideal mechanical advantage of a third-class lever?
mechanical advantage is the output force divided by the input force
What is the ratio of a lever?
The mechanical advantage of a level is the ratio of the output force to the input force.
How do you find the output force of a 1st class lever?
Multiply (the input force) x (the lever's mechanical advantage).
Why is the output force of a second-class lever always greater than the input force?
Because of the lever's mechanical advantage.
How do you calculate a lever's mechanical advantage?
From the design of the lever (on paper), the mechanical advantage is effort arm/load arm which means Distance from pivot to the applied force/distance from pivot to the load The result of that is that the forces will have the reciprocal ratio, and the input force to the lever will be the output force/the Mechanical Advantage .
How is input and output shown on a force diagram?
Input and output are shown on a force diagram by the human being the input force and the load force being the output force. When you divide output force by input force, you get the mechanical advantage of a lever.
What is the unit of mechanical advantage?
Simple machines, such as a lever, inclined plane, or wheel and axle, give you a mechanical advantage.You calculate the mechanical advantage of a simple machine by dividing the output force by the input force.
How is input and output shown on force diagrams on force?
Input and output are shown on a force diagram by the human being the input force and the load force being the output force. When you divide output force by input force, you get the mechanical advantage of a lever.
What is the mechancial advantage of lever that can lift a 100 N load with an input force of 20 N?
The mechanical advantage of a lever is that it can lift a 100N load with an input of 20N is calculated as is 5. In this case, the effort is divided by the load.
Is force the same thing as mechanical advantage?
No. You'll never see a bathroom scale that says your mechanical advantage is 140 pounds. The mechanical advantage of a device like a lever or a hydraulic jack is a measure of how the force changes between the input of the device and its output.
What does the mechanical advantage of a first-class lever depend upon?
The advantage of a first class lever is that by using less input force, you get more output force. Teehee!
What is a lever with a mechanical advantage greater than one used to do?
Mechanical advantage refers to the ratio of the force produced by a machine to the force applied to it. A lever with a mechanical advantage greater than one is used to increase distance.
