Can a lever multiply distance?
A lever is a simple machine that allows mechanical force to be exerted using a varying distance. Typically, the lever allows the use of a smaller force across a greater distance in the place of a larger force over a smaller distance.
Which class of lever does not multiply input force?
The first class lever (force, fulcrum, load) doesn't change the force if the lever is symetrical. Note that if it is assymetrical, the force will change.
Can a force produce a torque when there is no lever arm?
no because to get a torque you must multiply lever arm by force. If lever is zero, then torque is zero
How do you find the output force of a 1st class lever?
Multiply (the input force) x (the lever's mechanical advantage).
What lever allows you to apply the resistance force over a greater distance?
a factory lever
Why is the output force of a second-class lever always greater than the input force?
Because of the lever's mechanical advantage.
Does the first class lever make the force greater?
yer
What are the things that are belongs to lever?
a machine helps us do work because it can a)multiply force, b)multiply distance, or c)change the direction of force.
What is a disadvantage of a lever?
If you wish to multiply force and you are at the right end of the lever the only disadvantage would be the size.
What simple machine can change the strength of force?
The lever will create more force by requiring greater distance.
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.
True or false The fulcrum is closer to the force when a force multiplier lever is used?
False. A lever to multiply the force exerted has its fulcrum closer to the object than to the force is applied. This will increase the force but decrease the distance the object moves compared to the force end.
