Class levers have the resistance force between the effort force and the fulcrum?
Class 2.
How do the three classes of levers work?
Class 1: Fulcrum in the middle: the effort is applied on one side of the fulcrum and the resistance on the other side, for example, a crowbar or a pair of scissors.Class 2: Resistance in the middle: the effort is applied on one side of the resistance and the fulcrum is located on the other side, for example, a wheelbarrow, a nutcracker, a bottle opener or the brake pedal of a car. Mechanical advantage is greater than 1.Class 3: Effort in the middle: the resistance is on one side of the effort and the fulcrum is located on the other side, for example, a pair of tweezers or the human mandible. Mechanical advantage is less than 1.
Relationship between position of fulcrum and effort required to lift load?
A relationship between two of it are when load come closer to fulcrum, you need more effort to use. But if load go far away from the fulcrum, you need less effort to use. A relationship between two of it are when load come closer to fulcrum, you need more effort to use. But if load go far away from the fulcrum, you need less effort to use.
Point around which a lever rotates?
The fulcrum. A Lever is a rigid rod to which a force can be applied to overcome a resistance. The point at which a lever pivots is called the fulcrum.
What class lever is the mandible and where does the effort load and fulcrum go?
Third class: Fulcrum is the condyles, effort is the masseter muscle, and load is whatever you're chewing on.
How are the 3 kinds of levers classified?
The three kinds of levers are classified based on the relative positions of the effort, the resistance, and the fulcrum. In a first-class lever, the fulcrum is between the effort and the resistance. In a second-class lever, the resistance is between the fulcrum and the effort. In a third-class lever, the effort is between the fulcrum and the resistance.
What are parts are of a lever?
Fulcrum and a bar or plank.load fulcrum effortFulcrumthe parts of the lever are resistance,effort and the fulcrum
What are the parts a lever?

What are the fulcrum resistance and effort?
A fulcrum is the fixed point around which a lever pivots. The resistance is the force opposing the movement of the lever, while the effort is the force applied to move the lever. The position of the fulcrum relative to the resistance and effort forces determines the mechanical advantage of the lever system.
What lever has resistance between the axis (fulcrum) and the force (effort)?
In a second-class lever, the resistance is between the axis (fulcrum) and the effort. Examples include a wheelbarrow or a nutcracker.
What is the fulcrum between effort and resistance?
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
What lever has the resistance force between the effort force and the fulcrum?
In a lever, the resistance force is located between the effort force and the fulcrum. This setup creates a mechanical advantage that allows a smaller effort force to overcome a larger resistance force. The position and distance of the resistance force from the fulcrum determine the effectiveness of the lever system.
Is a broom an example of a second class lever?
Yes, a broom is an example of a second-class lever. In a second-class lever, the load is located between the fulcrum and the effort. When you push down on the handle of a broom to sweep, the load (dirt and debris) is located in between the fulcrum (floor) and the effort (your hand on the handle).
In what order do the effort fulcrum and resistance appear on a second class lever?
On a second class lever, the effort is applied at one end of the lever, while the resistance is located in the middle of the lever, between the effort and the fulcrum.
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
What is the position of Fulcrum Resistance and effort in a catapult?
In a catapult, the fulcrum is typically located at the base of the arm holding the projectile. The resistance is the force opposing the launch of the projectile, which is overcome by the effort applied to pull back the arm of the catapult. So, the fulcrum supports the arm, the effort is used to pull back the arm, and the resistance is the force opposing the launch.
What does the machanical advantage of a first-class lever depend apon?
The mechanical advantage of a first-class lever depends on the relative distances between the effort force, the fulcrum, and the resistance force. The mechanical advantage is calculated as the ratio of the distance from the fulcrum to the effort force to the distance from the fulcrum to the resistance force.
