Is it important for the effort force and load to be at the same distance from the fulcrum?

Not at all! A big part of what makes levers so useful is the ability to do
different things with them by moving the fulcrum either closer to the effort
or closer to the load.
The first example that pops into my mind is: A 200-lb father doing the see-saw
with his 6-year-old daughter. To get anything out of that experience, they need
the fulcrum much closer to Dad.
And by the way ... with a Second Class or Third Class lever, it's not even
possible to make those distances the same, since the effort and the load
are both on the same side of the fulcrum.

If the fulcrum is closer to the effort is the force less?
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.
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 makes the first class lever second class lever third class lever different?
1st order levers have the fulcrum between the load and effort arms. The mechanical advantage of these levers can be greater or less than 1, depending on the length of the arms.2nd order levers have the load portion between the effort portion and the fulcrum. These always have a mechanical advantage greater than 1. They increase the force exerted at the expense of distance.3rd order levers have the effort portion between the load portion and the fulcrum. These always have a mechanical advantage less than 1. They decrease the force exerted with a gain to the distance.
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
When is the effort force decreased in a first class lever?
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.
How does the position of the fulcrum and the location of the load affect the amount of effort force you must exert to lift the load?
To do this you first have to calculate your ideal mechanical advantage (IMA). The IMA is equal to the effort distance (the distance from the fulcrum to where you will apply the effort) divided by the load distance (the distance from the fulcrum to the load). You can then set your IMA equal to your acutal mechanical advatage (AMA) which assumes 100% efficiency. The AMA is equal to the load force (the weight of what you are lifting) divided by the effort force (the # you are looking for). So, for example, if your IMA is 5 and your load force is 500 lbs: 5=500/effort force. Therefore the effort force would be 100 pounds.
If the fulcrum is closer to the effort is the force less?
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.
What do you need to know to calculate the mechanical advantage of a compound machine?
torque in * input rpm/output rpm = torque out
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 between a fulcrum and effort force?
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.
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 is the part of a lever on which the effort force is applied is called?
Fulcrum
What is force times distance?
Torque is calculated by multiplying a force by the distance from the fulcrum at which it acts.
How do you calculate the mechanical advantage of a simple machine?
In the distance from the fulcrum to the input forcedivided by the distance from the fulcrum to theoutput force.
