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.
What is the pulley?
A pulley is a simple machine that helps you carry heavy objects without using a large amount of force.
What is one advantage of using a pulley system?
By using a pulley one can easily do things with less effort
Uses of single pulley?
it can help by pulling heavy loads using a rope
A load can be lifted easily by?
A load can be lifted easily by using a pulley system.
Can weed get out of your system by lifting weights?
nothing will get weed out of your system except quit using it for at least a month.
What pulley system will lift the weight using the least amount of effort force?
balls. =))
What are the advantages and disadvantages of using a pulley?
Advantages - a pulley allows you to apply force in any direction, not just the one in which the force is to applied. Multiple pulleys yield a mechanical advantage that can allow the lifting of heavy weights. Disadvantages - the pulley has to be securely anchored to support the mass being acted on, and the rope has to be strong and durable. A wheeled pulley needs to rotate smoothly, and a sliding (e.g. wooden) pulley should not abrade the rope. Also, the more pulleys you use, the more rope you need. You need to consider the strength of the pulley's anchorage. If you try to raise a 40 lb load using a rope over a single pulley hung from the roof with the 2 legs of the rope parallel, the force on the anchorage will be 2 x 40 = 80 lbs.
1 pulley system more efficient then a 2 pulley system?
Efficiency is the proportion of energy usefully used. Using a pulley system does not use less energy it just changes the ammount of force. Pulleys do have a small ammount of friction so having just one pulley would be more efficient. (but not much more)
Which early American leader in physical education believed that lifting lighter wooden weights and using higher repetitions was more beneficial than lifting heavy metal weights?
Dio lewis
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.
How does the different type of pulley system affect the mechanical advantage?
Depending on the type of pulley system you have (Fixed/ movable/ combined pulley) using either of these will give you mechanical advantage. The different pulley types are designed to even the weight of the object your pulled out, this will enable you to lift heavier objects with a lighter pull
