How does a greater mechanical advantage benefit a machine?
Lever: A lever consists of a rigid bar (the lever arm) that pivots around a fixed point called the fulcrum. By applying a force at one end of the lever, you can lift or move a load at the other end. Depending on the positions of the force and load relative to the fulcrum, levers can amplify force or distance. Pulley: A pulley is a wheel with a groove that holds a rope, cable, or belt. When you pull on one end of the rope, it moves the load attached to the other end. Fixed and movable pulleys can change the direction of force or provide a mechanical advantage, making it easier to lift heavy objects. Wheel and Axle: A wheel and axle consist of a larger wheel connected to a smaller axle. When force is applied to the wheel, it generates rotational motion that can be used to move loads. The mechanical advantage depends on the ratio of the wheel's radius to the axle's radius. Inclined Plane: An inclined plane is a flat surface that is sloped. By sliding an object along the inclined plane, you can exert a smaller force over a longer distance to move the object to a higher or lower elevation. This reduces the force required to lift the object vertically. Wedge: A wedge is a double-inclined plane used to split or separate objects. When you apply force to the thick end of the wedge, it generates a large force at the thin end, making it useful for cutting, splitting, or prying. Screw: A screw is an inclined plane wrapped around a cylindrical shaft. When you rotate the screw, it moves along its threads and can lift or hold objects. Screws provide both a mechanical advantage and a way to generate motion over a distance.
Do windmills have pulleys?
no
What is the disadvantage of adding more pulleys to a system of pulleys?
There are two disadvantages:You will have to pull the rope a long distance to move the load a relatively short distance.There will be more loss of energy to friction with more pulleys.
Do trebuchets have pulleys?
Yes they do.
What is the advantage of adding pulleys to a pulley system?
More mechanical advantage.
Explain why pulleys are in the lever family?
They provide mechanical advantage.
What is the mechanical advantage of systems of pulleys?
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
How do you find the mechanical advantage of a simple machine?
To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
How can you increase a pulleys mechanical advantage?
By increasing the effort distance on the machine.
a pulley system uses a 250-N force to lift a 2,740-N crate, What is the mechanical advantage of the system?
Answer: Mechanical advantage can be achieved just by adding more loops or pulleys. It is given that to lift a crate, a pulley system exerts a force of 2,740 newtons. It is required to find the mechanical advantage of the pulley system if the input force is 250 newtons What is the mechanical advantage of the pulley system if the exerted force changes from 2,740 newtons to 250 newtons? As if the force does some work, it increases the distance. Mechanical advantage does nothing with the number of pulleys. It only depends on the weight that is to be lift. Also, F1/F2 = 2740/250 = 10.96 The multiple pulleys create mechanical advantage. It can be achieved just by adding more loops or pulleys. Therefore, Mechanical advantage can be achieved just by adding more loops or pulleys.
How is a fixed pulley different from a movable pulley?
A fixed pulley is different from a movable pulley because a movable pulley has one end of the rope attached to it fixed on an unmoving object. The pulley is free to move with the rope. You pull the other end of the rope. Also, a movable pulley multiplies the applied force (effort force) and therefore has more mechanical advantage. A fixed pulley is attached to something that doesn't move, while one end of the rope is holding the weight, while the other is for pulling.A fixed pulley confers no mechanical advantage, but will convert motion in one direction into another direction.A movable pulley system, if the pulleys change their distance from each other, will confer a mechanical advantage.
Why does a fixed pulley have a mechanical advantage of one and a movable pulley has a mechanical advantage of two?
we find mechanical advantage of pulley by using principle of lever. according to this moment of effort is equal to moment of moment of load. As in this case effort arm is equal to load arm. so mechanical advantage is equal to one. but we know we can never finish friction between rope used and pulley so mechanical advantage is less than one
What will increase the actual mechanical advantage of a machine?
Common mechanisms for obtaining mechanical advantage would include such as multiple pulleys, hydraulic systems, gears, and levers.
What is the disadvantages of movable pulleys?
movable pulleys sometimes don't have a directional advantage so you have to pull up and you can't use a weight as the effort and whoever said this its wrong so next time USE THE TEXT BOOK STUPID PERSON sorry about this my friend can be mean.
What type of advantage describes the ability of a machine to incresae output force?
Mechanical Advantage [achieved through levers or pulleys]
How is the mechanical advantage of a movable pulley determined?
The method to calculate mechanical advantage is easy to remember and is necessary when rigging the assembly to accomplish the job. The mechanical advantage of a rigging that will require upward pull can be determined by counting the number of rope lengths running between engaged pulleys and those doing the work. Likewise, if the assembly will require downward pull, count the ropes and subtract one to get the mechanical advantage number. The subtraction is necessary because with the fixed pulley, the downward pull equals the load on the other length of rope so the last "pull" rope does not provide any mechanical advantage.
