When you want to pull to lift something the main advantage of passing a rope upward and through a single pulley rather than just up over the branch of a tree is that the pulley?
The rope pulled over the branch is hampered by the rope's friction over the branch. The same rope pulled over a pulley is not affected by friction as the pulley wheel will turn as the rope is pulled.
What will be the tension in a rope that is pulled from its ends by two opposite forces 100 n each?
Neglecting the weight of the rope itself, the tension will be 100 newton in any part of the rope.
What will be the tension in a rope that is pulled from its end by two opposite forces 100Newton each?
In that case (ignoring the weight of the rope, for simplicity), the tension at any point of the rope will also be 100 N.
Which pulley system can make work easier?
A pulley halves the force required to lift a load, but doubles the length of rope or cable. So if you had a 10lb. weight attached to a rope, and were pulling the rope upward, you would need 10lbs. of force to lift it. However, if you had a pulley attached to a beam overhead, and were pulling down on the rope, you would only need 5lbs. of force to move the weight, but you would need to pull twice as much rope to get the weight to move the same distance.
What is puley?
A (simple) pulley is a single wheel over which a rope is pulled in order to lift a weight - a crane is an example. A multi-pulley wheel system allows a very heavy weight to be raised by using little effort at the rope pulling end. Pulley's, in their many examples, were much used in sailing ships, were canvas sails were used the capture the power of the wind to sail the seas.
What is the definition of a rope and pulley?
A device used to lift something heavy. By using a pulley, you half the effective weight.
You set up a pulley to help you lift something you anchor the rope at one end and arrange a moveable pulley to achieve a mechanical advantage of 2 by the time you have lifted the object 5m off the gro?

What would happen if both dogs pulled the rope pulled the rope with a force of 85 N?
Then neither of them would win
24lbs of weight hanging on a pulley how much force is needed to lift the weight?
If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.
What will be the tension in a rope that is pulled from its ends by two opposite force 100 each?
the tension in rope is equal to the sum of the two forces
What is the name of the force on a rope when both ends are pulled in opposite directions?
Pulling is the main force in ropes, as you pullthe rope.
Which force happens when a rope or chain is pulled harder in two different directions?
You get a tension in the chain or rope.
