How does a pulley decrease work?
A pulley decreases the amount of work needed to lift an object by distributing the force required over multiple ropes and pulleys. This reduces the amount of force needed by the person pulling the rope, making it easier to lift the object.
What are Advantages of digital thermometers?
You can read the temp a lot easier.
How does a movable pulley make work easier?
A fixed pulley is the only pulley that when used individually, uses more effort than the load to lift the load from the ground. The fixed pulley when attached to an unmovable object e.g. a ceiling or wall, acts as a first class lever with the fulcrum being located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push the pulley up and down. The disadvantage is that you have to apply more effort than the load
Does a pulley system cause the direction of the output force to be opposite to the direction of the input force?
A pulley system may cause the direction of the output force to differ from that of the input force, but is not guaranteed to do so. In a simple example, a double pulley could easily result in input and output forces in parallel.
How can a fixed pulley make work easier?
A fixed pulley changes the direction of force applied, allowing the force needed to lift an object to be distributed more evenly. This can make work easier by requiring less effort from the person lifting the object.
What is a compound pulley?
a coumpound pulley is when there is a fixe pulley and movable pulley working together
What is compound pulley?
a coumpound pulley is when there is a fixe pulley and movable pulley working together
Is a combined pulley easier to lift any other pulley?
A combined pulley system makes it easier to lift an object compared to a single pulley system. By distributing the load across multiple pulleys, the force required to lift the object is reduced.
How can pulleys make life easier?
The pulley makes work of lifting easier then lifting by hand.
Why is it good to have an air conditioning?
It will raise the value of the vehicle plus its a lot easier to sell the vehicle with a working a/c system.................
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.
Why it is easier to lift the same load by using three -pulley system than two-pulley system?
A three-pulley system allows the load to be distributed among three supporting strands, making it easier to lift the load as each strand bears less weight compared to a two-pulley system where the load is evenly distributed between only two strands. The mechanical advantage of the three-pulley system reduces the amount of force required to lift the load, making it easier to lift.
Why is a pulley is a lever?
Because they both reduce friction, making your work easier
How does a fixes pulley make doing work easier?
it deacreases the input force
Why is a lever a pulley?
Because they both reduce friction, making your work easier
Is a wheelbarrow a type of pulley?
yes because it makes things easier to move.
What are the use of pulley in simple machine?
it makes our work faster,easier and better
