A lever is used to lift a load with a resistance force of 500 n the load is 1 m from the fulcrum how far from the fulcrum must the effort force of 250 n applied to lift the load?

500 n * 1 m = 250 n * x m
x = ( 500 n * 1 m ) / 250 n.m = 2
Then the force must be applied at 2 m from the load. Actually apply this force at this distance will merely balance the load, won't it? To move the load would require either a slightly greater force or moving the 250 n force slightly farther away from the fulcrum.

Where is the fulcrum resistance force and the effort force on a shovel?
The effort force is applied at the handle of the shovel. The fulcrum is where your other hand goes, lower down the shaft, and the fulcrum resistance would be where the load goes on the shovel, I.E the flat bit that you hit people with!
What. Are the parts of a lever?
Fulcrum and a bar or plank.load fulcrum effortFulcrumthe parts of the lever are resistance,effort and the fulcrum
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 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
Class levers have the resistance force between the effort force and the fulcrum?
Class 2.
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.
What is the part of a lever on which the effort force is applied is called?
Fulcrum
Knife is what classification of levers?
A knife can be classified as a Class 1 lever. The classification of levers is based on the relative positions of the effort (force applied), the fulcrum (pivot point), and the load (resistance or object being moved). In a Class 1 lever: Fulcrum (F): The fulcrum is located between the effort and the load. Effort (E): The effort is applied on one side of the fulcrum. Load (L): The load is on the other side of the fulcrum. In the case of a knife: Fulcrum (F): The point where the knife pivots, usually where the handle meets the blade. Effort (E): The force applied by the user to cut or slice through the food. Load (L): The resistance or the material being cut, such as vegetables, meat, or other food items. When you use a knife, you apply force (effort) on the handle, causing the blade to pivot around the fulcrum and exerting force on the material being cut (load). Class 1 levers are characterized by their balanced arrangement, where the effort and load are on opposite sides of the fulcrum.
In what class lever is the resistance arm always longer than the force arm?
The class 3 lever always has a longer resistance arm than the force arm. This is because the distance from the Fulcrum to the load/resistance is always going to be further that the fulcrum to where the effort/force is applied. If you look at a diagram of a 3rd class lever, you will be able to see why this is.
Part of a lever on which effort force is applied?
Third class.
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 is another word for fulcrum?
The fulcrum is the support about which a lever pivots.The fulcrum is the pivot point in a lever (or other simple machines ) to either multiply the mechanical force (effort) that can be applied to another object or resistance force (load), or multiply the distance and speed at which the opposite end of the rigid object travels. =]
