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 happens when the fulcrum is further from the load?
The closer the load is to the fulcrum the greater the mechanical advantage. The closer to the fulcrum, the less the load moves when the lever is used.
When is mechanical advantage increased by a first class lever?
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
If a fulcrum was moved toward a load what would occur?
That's actually only possible in a First Class lever. In that case, moving the fulcrum closer to the load makes it easier to lift the load, since it now takes less force at the effort end. But the effort force also has to move through a greater distance than it did before, in order to lift the load to the same height.
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.
As you increase the effort distance what will happen to the force needed?
When you move a fulcrum as close as you can to the effort force and farthest away from the load, you are pushing on the short end of the lever, so it requires the most effort force to push on the lever and lift up the load. When you move the fulcrum farther away from the effort force and closer to the load, you are pushing on the long end of the lever, so it requires less effort force to lift the load.
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.
Where are the load effort and fulcrum located on a second class lever?
No, the function of the fulcrum remains the same The only change would be the ratio of force to load The closer the fulcrum is the the load, the less force required to lift it The farther away the fulcrum is from the load, the more force required to lift it
What happens when the fulcrum is further from the load?
The closer the load is to the fulcrum the greater the mechanical advantage. The closer to the fulcrum, the less the load moves when the lever is used.
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.

What part of LEVER?
the fulcrum, load and effort The three parts of a lever , fulcrum, resistance arm and effort arm, work together to make it possible to lift a weight using less force ...

What do fulcrums help?
A fulcrum is the point of tuning for a lever. Since a fulcrum is essential for a lever, it does not help but rather is needed. The lever and fulcrum are used to move or hold objects. Levers can be used change the amount of force needed to alter a system of load, lever, and effort. The position of the fulcrum determines the force needed to change the natural equilibrium. There are three classes of levers divided in accordance to the position of the fulcrum. The first class of lever is typically used in a gravitational field with a load at one end of the lever, the fulcrum closer to the load than the middle of the lever, and a force applied near the other end of the lever. The important point is that the fulcrum is between the two forces and on the opposite side. If the lever is longer on the force side, the force needed to move the load is less than the weight of the load, but the load travels a smaller distance than the applied force point moves. This would be used possibly to lift an heavy object. By placing the fulcrum close to the point of force, the load moves farther than the applying force. This can be demonstrated by observing a trebuchet (commonly referred to as a catapult) The second class of lever places the load and the force on the same side of the fulcrum with the load closer to the fulcrum than the applied force. An example of this is the wheelbarrow. Again, the force needed to lift the load is less than the weight of the load. The third class of lever places the force between the fulcrum and the load. Examples of uses for this are chopsticks or ice tongs.
How are first and second class levers different?
the first class levers have the fulcrum in the middle and the resistance and effort on the two sides second class levers have the resistance in the middle and the fulcrum and the effort on the two sides
Why is the fulcrum in pliers so close to the load?
Consider a wheelbarrow: When the weight is closer to the wheel, there is less load on the lever or handle. M = F*d Moment = Force x distance In this case, force is the mass of the object in the wheel barrow, and distance is distance from fulcrum. So, the smaller the distance, the lower the "moment" or lifting effort. When the distance = the length of the lever, you are basically lifting the entire force.
