A lever is used to lift a 50 kg object at a constant speed if the applied force exerted on the lever is 100N what is the mechanical advantage of the lever?
The weight of the 50 kg object is (50 x 9.8) = 490 newtons.In order to lift the object with a force of 100 N, you need a mechanical advantage of 4.9 .That's the net mechanical advantage of the lever system, including all of its friction losses.
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
Why is the output force of a second-class lever always greater than the input force?
Because of the lever's mechanical advantage.
If a lever with a mechanical advantage of 13 is used to move a rock with a force of 845N what is the imput force?
the answer is 65
What is the Mechanical Advantage of levers?
The mechanical advantage of the lever is that smaller persons can move heavier objects. The lever can be placed under the object and the person can then push down on the lever.

What is the formula for finding weight at simple lever?
a lever has a mechanical advantage of 5 . how heavy an object can the lever move if a person exerts 100N force on the lever?
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 .

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
How do you find the output force of a 1st class lever?
Multiply (the input force) x (the lever's mechanical advantage).
What is the ratio of a lever?
The mechanical advantage of a level is the ratio of the output force to 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.
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.
If a lever with a mechanical advantage of 13 is used to move a rock with a force of 845N what is the imput force?
the answer is 65
What was the first machine invented?
probably the lever, which offers mechanical advantage (force multiplication)
