The force lever uses to lift a load is?
determined by the length of the lever arm and the weight of the load. The longer the lever arm, the less force is needed to lift the load. The force needed is inversely proportional to the length of the lever arm.
What simple machine does a wheelbarrow use to lift a load?
A wheelbarrow uses a lever as a simple machine to lift a load. The handle of the wheelbarrow acts as the lever, allowing the user to exert a force to lift the load placed in the container.
How does lever use its mechanical advantage?
A lever uses its mechanical advantage by allowing a small force to lift a larger load by increasing the distance over which the force is applied. This is achieved by positioning the fulcrum closer to the load and farther from the effort force, distributing the work more efficiently.
What does the wheelbarrow use to lift a load?
A wheelbarrow uses a lever to lift a load. The handles act as the effort arm, while the wheel and the load act as the resistance arm, allowing the user to easily move heavy items by leveraging the load against the wheel.
What simple machine uses a wheel with a rod or rods through its center that will help it lift or move a load?
A pulley system uses a wheel with a rod through its center to lift or move a load. The pulley reduces the amount of force needed to lift heavy objects by distributing the weight across multiple ropes or chains.

In a class 3 lever is the effort force ever less the force exerted on the load?
A class three lever uses an operating force between the fulcrum and the load. The movement on the load will therefore be larger than the movement of the force. The force applied to the lever will always be less than the force exerted on the load.
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.

What a lever does?
A lever is a simple machine that uses variable distance to multiply force, or to redirect existing forces. With a lever, the force exerted by gravity on a weight can be used to lift another weight. By varying the distance between a lever's ends and its fulcrum, a heavy object can be lifted a short distance by a smaller force moving a longer distance.
What are the function of a lever?
The lever helps you lift objects you can't physically lift. It uses Archimedes' leverage principle.Levers can also redirect force to make it easier to apply :-- a hammer uses the lever principle to pull out a nail-- seesaws balance a downward force (weight) on either side to lift the opposite sideA lever has two possible applications:-- multiply the force you apply and make it a larger force, by sacrificing the distancethat the force moves through;-- multiply the distance through which you move a force and make it a larger distance,by sacrificing the strength of the force.The product of (force) multiplied by (distance) is always the same at both ends of the lever.But by using the lever, you trade a part of one of them in order to increase the other one.A lever allows you to lift and elevate an object up in the air.>It gives you mechanical advantage (MA)MA = distance moved by effort / distance moved by loadOutput force = input force * MA
What simple machine uses a wheel with a rod or rods through its center that will help it lift or move a load?
A pulley system uses a wheel with a rod through its center to lift or move a load. The pulley reduces the amount of force needed to lift heavy objects by distributing the weight across multiple ropes or chains.
What are the uses of the 3 parts of lever?
The lever consists of three parts: the fulcrum, the effort force, and the load or resistance. The fulcrum is the point around which the lever pivots, the effort force is the force applied to move the lever, and the load or resistance is the object being moved. These parts work together to help lift or move heavy objects with less effort.
What type of simple machine is in a broom?
A standard broom is a lever, which translates some force in the horizontal direction. The motion of one hand uses the other hand as a fulcrum, allowing the force of both hands to be exerted in the same direction. Either hand can be considered as a stationary or moving fulcrum. With the fulcrum at the top hand, a broom is a class 3 lever (load and force on same side of fulcrum). With the fulcrum fixed at the middle hand, a broom is a class 1 lever (force and load on opposite sides of the fulcrum). Push brooms and whisk brooms are not levers.
Is a block and tackle an example of a rotational force transformer?
Yes, a block and tackle is an example of a rotational force transformer. It uses multiple pulleys to multiply the input force to lift heavy objects. The rotational force applied to the pulleys transforms into a greater vertical force to lift the load.
