What force a lever uses to lift a load is?
A lever uses mechanical advantage to lift a load. This is achieved by applying a smaller force over a greater distance to move a larger force over a shorter distance.
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 is between the fulcrum and input force on a lever?
The load or resistance is positioned between the fulcrum and the input force on a lever. The input force is applied on one side of the fulcrum, while the load is typically located on the opposite side. The lever uses this arrangement to magnify the force applied to move the load.
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.

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.

Is a crowbar a pulley or a lever?
A crowbar is a lever because it has a fixed fulcrum (the pivot point) that allows it to lift or move heavy objects by applying force at one end. It is not considered a pulley, which uses a wheel and rope to lift objects by changing the direction of the force applied.
What type of pulley uses more effort than the load to lift the load from the ground?
A fixed pulley requires more effort than the load to lift it from the ground. This type of pulley changes the direction of the force applied but does not provide any mechanical advantage in terms of reducing the effort needed to lift the load.
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 uses of a second class lever and a third class lever?
A second class lever is often used to increase force or speed, such as in a wheelbarrow, where the load is in between the fulcrum and the effort. A third class lever is commonly used to increase distance and speed, like in a fishing rod, where the effort is in between the fulcrum and the load.
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.
