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 are the 3 classes of levers?
Levers are classified into three types (first-class, second-class, and third-class) depending on the relative position of the fulcrum (pivot point), the point of applied (input) force, and the location of the load (output force). In a first-class lever, the fulcrum is between the input force and the output force, and the load is moved in the opposite direction of the applied force. Placing the fulcrum closer to the load gives an advantage of force (less force needed to move the load a shorter distance), while a fulcrum closer to the point of applied force gives an advantage of distance (the load is moved a greater distance but more applied force is needed). First-class levers include a crowbar, using a hammer's claw end to remove a nail, and a pair of scissors. In a second-class lever, the load is between the fulcrum and the point of applied force, so both forces move in the same direction. Less force is needed to move the load, but the load does not move as far as the direction over which the input force must be applied. Examples include the wheelbarrow, a bottle opener, and a door on its hinges. In a third-class lever, the input force is applied between the fulcrum and the load, and both move in the same direction. The amount of applied force is always greater than the output force of the load, but the load is moved a greater distance than that over which the input force is applied. Examples include a hammer driving a nail and the forearm of a person swinging a baseball bat.

How can a spill of a solution affect the experiment?
By not having the right amount. jamaul
How does the diameter of wire coil affect the amount of electricity?
The diameter of the coil affects the amount of electricity as longer the coil longer the electricity.
Does temperature affect the amount of substance dissolved in a saturated solution?
Yes temperature affects the amount of substance dissolved in a saturated solution.
The rate at which an object changes position is called what?
A change in position in a certain amount of time is called motion.
What position should the gear shift lever be in when tightening?
To lift the rock using the least amount of effort force,should push on the position farthest away from the fulcrum. This is position Z.
Is it true or false that as the position of the fulcrum changes the amount of force needed to move a box remains the same?
The force at the box would remain the same is true.
How does moving fulcrum on a lever change the amount of force needed to move an object?
how does moving a fulcrum on a lever change the amount of force needed to move an object
What factors affect population growth?
Location, amount of people, town.
What will affect the amount of gravitational potential energy?
The mass, height and the force of gravity at the location.
Why does the amount of sunlight at each location change?
Because of the axial tilt of the earth and the position of the earth in its orbit.
The distance of any object from fulcrum?
Adds or subtracts from the amount of force(PSI).
What is position and how can it be measured and expressed mathematically?
Position is the location measured from a reference point with direction and magnitude(amount). SI Unit: meters(m) Position= x(or y) Lauren "Physics above all!"
What is the relationship between the amount of effort needed to lift the load and the distance of load from the fulcrum?
confusing
Water cycle effect water amount?
No it does not affect the amount of water, but only change the position
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.
Which type of machine changes the direction or amount of force needed to do work?
simple machines like pulley, liver and fulcrum.
