A simple machine such as a pulley is used to make work easier. Erin used 50 newtons of force to lift a crate 3 meters. She then tied the crate to a pulley and used the pulley to lift the crate again.?

Using a pulley would require Erin to exert less force but over a longer distance compared to lifting the crate directly. The work done by Erin using the pulley system would be the same as lifting the crate directly, but she would need to pull the rope further to achieve the same result.

By using a pulley, Erin can reduce the amount of force needed to lift the crate. If Erin uses a single fixed pulley, she would still need to apply 50 newtons of force to lift the crate, but it would require less physical effort due to the change in direction of the force. If she uses a more complex pulley system, like a block and tackle, she could further reduce the amount of force needed, making it even easier to lift the crate.
What type of simple machine is a window shade?
A window shade is a type of pulley system simple machine. It uses a pulley to raise and lower the shade, making it easier for users to control its position.
A moving company uses a machine to raise a 900-newton refrigerator to the second floor of a building. The machine consists of a single pulley with a mechanical advantage of 1. How many newtons of inpu?
If the mechanical advantage of the pulley is 1, then the input force needed to lift the 900-newton refrigerator is also 900 newtons. This means that the moving company would need to apply a force of 900 newtons to raise the refrigerator to the second floor.
What is a pulley - gr 4 class?
A pulley is a simple machine that consists of a wheel with a groove in its edge and a rope or cable that runs along the groove. It is used to lift or lower objects by applying force to the rope. Pulleys make it easier to move heavy loads by allowing us to change the direction of the force applied.
Pulling down on a rope to hoist a sailboat is an example of a machine?
Yes, pulling down on a rope to hoist a sailboat is an example of a simple machine called a pulley. The pulley makes it easier to lift the weight by changing the direction of the force applied.
