What force a lever uses to lift a load is?
effort force
What are the uses of double pulley in physics?
The amount of force required to lift a weight is inversely proportional to the number of suspension lines. A multiple pulley system allows the load to be distributed across several lines and greatly reduces the amount of force required to lift the weight.. The load that takes mechanical power to lift with a single pulley can be lifted by a single person with a multiple pulley set-up
Is a trebuchet a Force Magnifier or a Distance Magnifier?
I'm unsure as to what exactly a distance magnifier is so hopefully someone with expertise in trebuchets can add to this. However I am confident that a trebuchet works on the principle of a lever. A lever is a force magnifier. Yet a trebuchet also uses a sling to launch the projectile in a parabolic arc which has the effect of increasing the distance, so perhaps it qualifies as both? A lever is most often used as a force multiplier, where the load moves through a smaller distance than the applied force, but in the case of a trebuchet the lever is used in the opposite sense. The load moves through a greater distance than the applied force and so the trebuchet is a distance multiplier.
What makes a garlic press a simple machine?
A garlic press uses a lever and has its fulcrum at one end of the lever arm. The load (garlic) is between the fulcrum and the effort. When using a simple machine like the garlic press we gain a mechanical advantage by increasing the amount of force we wish to use.
What's a lever used for?
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 force a lever uses to lift a load is?
effort force
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?

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 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.
How does a simple machine make a hand brake work?
A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. They can be used to increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the force.

What part of a hammer is a simple machine?
it is a lever because it has the effort, fulcrum and load official

What are the 3 types of lever?
THREE CLASSES OF LEVER There are three classes of lever and each class has fulcrum, load and effort which together can move a heavy weight. CLASS 1 The workman uses a trolley to move the large packing case. The fulcrum is the wheel. CLASS 2The gardener uses a wheel barrow to lift tools and garden waste. The load is in the centre of the barrow CLASS 3 The fisherman catches the fish which becomes the load at the end of the lever.
