a 1st class lever
there are 3 types of levers, 1st 2nd and 3rd class.
1st: fulcrum between effort and resistance
2nd:resistance between fulcrum and effort
3rd: effort between fulcrum and resistance
Fulcrum = a pivot point on a lever.
Effort = force applied on lever
Resistance = load
1st example:see-saw/scissors
2nd example:wheelbarrow/car door
3rd example:someone raking/ hockey stick being usued

Why is tiptoe a second class lever?
Because a second class lever is a lever in which the resistance is located between the fulcrum and the effort. When you stand on your tiptoes, the fulcrum is located at your toes, the effort is at your Achilles tendon, and the resistance is the weight of your body pushing down. therefore, the resistance is between the fulcrum and the effort.
In what class of a lever is the effort between the fulcrum and the resistance?
Class 3.
Where is the fulcrum located in a class one lever?
between effort and the load i.e the resistance we have to overcame
What is the position of Fulcrum Resistance and effort in a catapult?
the position is that lever is near fulcrum exposed to the left sex of the effort which makes the effort to troposphere
How do first class levers work?
distance from fulcrum to point of effort is de distance from fulcrum to point of resistance is dr Force applied is called the effort, Fe The weight of the object to resistance, Fr Ignoring the weight of the lever itself ... IDEALLY Fede = Frdr Effort ---- fulcrum ---- resistance (not necessarily equal lengths) In this illustration, effort pushes down on left, resistance is lifted up on right.

Class levers have the resistance force between the effort force and the fulcrum?
Class 2.
Where is fulcrum effort and resistance on a broom?
where your hand is, your lower hand is the fulcrum.
Where is the fulcrum located in a class one lever?
between effort and the load i.e the resistance we have to overcame

What is the position of Fulcrum Resistance and effort in a catapult?

What are the 3 parts of a lever?
A Lever comprises of three components:Fulcrum or Pivot - the point about which the lever rotatesLoad or Resistance - the object that requires movingEffort - the force applied by the user of the lever system
