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
Fulcrum and a bar or plank.load fulcrum effortFulcrumthe parts of the lever are resistance,effort and the fulcrum
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.
the force is less because if the fulcrum is father away from the effort the force will increase and become greater. so if the fulcrum is closer to the effort there will be less force.
the fulcrum lies between the effort and load the effort or force and makes it possible to perform the work
Class 2.

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!

It depends on which type of lever you are using. If it is a Class II lever then the load is between the fulcrum and the effort.
The effort-to-load force in a first class lever is decreased when the distance between the effort and the fulcrum is less than the distance between the fulcrum and the load.
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

The resistance and effort in a clothespin come from the spring mechanism. When you open the clothespin, you're working against the tension in the spring, and when closed, the spring provides the clamping force, creating the resistance to keep it shut.

Yes.
