What else can I help you with?
If a person wants to raise the 100 N weight how much downward force must he exert on the rope?
If you have a single pulley, then you would need to exert 100N + an amount to overcome friction in your pulley.If you have 2 pulleys, rope connected to a beam at top, descends through pulley on item lifted, and back up through pulley at the top and then down to where you are pulling. Then the force is split in half and you would exert 50N + an amount to overcome friction.If you connect a rope to the item, up through a double pulley, down through a pulley on the item, and back up through the double pulley again and down to the person who is pulling. Then you divide the force into thirds, and the force is 33.3N + an amount to overcome friction.Essentially count the upward pulling ropes and divide by that number. A rope simply looping over a pulley that you're hanging onto the other end of only counts as once, and would be no different from you pulling up directly on the object, or on a pulley connected to the object.
When you stand on a bathroom scale it displays the blank the earth is exerting on you?
When you stand on a bathroom scale it displays the force the earth is exerting on you, which is your weight. The scale measures the gravitational force between you and the earth such that the reading you see is your actual weight in that gravitational field.
Which force changes Earth's surface most slowly?
The force that changes Earth's surface most slowly is typically erosion, which is the gradual wearing down of rocks and soil by wind, water, and other natural forces. This process can take thousands to millions of years to significantly alter the landscape.
Breaking down rock by physical force?
The process of breaking down rock by physical force is known as mechanical weathering. This can be caused by factors such as temperature changes, pressure changes, or the action of ice and water in cracks and crevices. Over time, this can lead to the fragmentation and breakdown of rocks into smaller pieces.
What is the study of wind called?
The study of wind is called aerodynamics. It involves the analysis of the movement and interaction of air and gases in response to force and pressure changes.
A fixed pulley changes what force?
A fixed pulley changes the direction of the input force without changing its magnitude. It can make it easier to lift or move an object by allowing the force to be applied in a more convenient direction.
What is an effect on fixed pulley?
The fixed pulley only changes the direction of the force applied.
A fixed pulley changes the?
... direction of a force.
A single fixed pulley changes the direction of the?
single fixed pulley changes the direction of the applied force, you pull down, the object goes up.
In a fixed pulley the effort force is equal to the?
In a fixed pulley, the effort force is equal to the load force being lifted. The fixed pulley changes the direction of the force applied, but does not provide any mechanical advantage in terms of reducing the amount of effort needed to lift the load.
What is the difference between a fixed pulley and movable pulley?
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.
Is a well a fixed pulley or a movable pulley?
A well is a fixed pulley. It changes the direction of the force applied to lift a bucket of water, but it does not move itself.
What kind of pulley changes the direction of input force but does not change amount of force you apply?
A single pulley alters the direction of the input but confers no mechanical advantage.
What is the mechanical advantage of a single fixed pulley?
Thew pulley changes the direction of the effort force.
What type of pulley changes the direction of the input force but does not change the amount of force you apply?
A fixed pulley changes the direction of the input force without changing the amount of force applied. It is attached to a fixed point and does not move, simply redirecting the force in a different direction.
What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.
How does the resistance force relate to the effort force for the fixed pulley alone?
In a fixed pulley, the resistance force is equal to the effort force when neglecting friction. This means that the input force required to lift a load is the same as the output force exerted by the load. The fixed pulley changes the direction of the force but does not provide any mechanical advantage.
