In which type of lever is the direction of the input force opposite of the direction of the output force?
That's a Class-1 lever, where the input and output are on opposite sides of the fulcrum.
What simple machine is the output force less than the input force?
Some Class-I levers, and all Class-III levers.
What do first-class levers always change the direction of?
Ur face
What class of levers are nutcrackers?
they are second class levers
Are scissors third class levers?
Yes scissors are third class levers
In which type of lever is the direction of the input force opposite of the direction of the output force?
That's a Class-1 lever, where the input and output are on opposite sides of the fulcrum.
What do first class levers always change the direction of?
First class levers change direction of force applied, like using a crow bar to open a door.In a first class lever, the fulcrum is between the force arm and the resistance arm. Seesaws, crowbars, and oars are first-class levers.
What simple machine is the output force less than the input force?
Some Class-I levers, and all Class-III levers.
What are the three classes of levers and an anatomical example of each one?
First Class Levers The fulcrum is between the input force and the load Always changes the direction of the input force and can be used to increase the force or the distance Second-class levers The load is between the fulcrum and the input force Does not change direction of the input force Output force is greater than the input force. Third-Class lever The input force is between the fulcrum and the load Does not change the direction of the input force Output force is less than input force.
What the first class levers change the direction of?
Ur face
What do first-class levers always change the direction of?
Ur face
What do first class levers do?
First class levers change direction of force applied, like using a crow bar to open a door.In a first class lever, the fulcrum is between the force arm and the resistance arm. Seesaws, crowbars, and oars are first-class levers.
What is the ideal mechanical advantage of a machine that changes only the direction of the input force?
There are three types of levers namely first, second and third class. First class levers can change the direction of input force.
What class of levers are nutcrackers?
they are second class levers
Does a first class lever change the direction of the force?
yes it changes the direction, and increases the force
Classification of levers?
There are three different Classes of levers. Class One Levers have a fulcrum in the middle. Class Two Levers have a resistance in the middle. Class Three Levers have effort in the middle.
Are scissors third class levers?
Yes scissors are third class levers
