How does pulleys make things easier?
A simple pulley as on a flagpole does avoid climbing the pole, but the effort to raise the flag is still the same. In fact there will be a small loss of energy due to friction in the pulley.You have to have at least two pulleys, before any effort is reduced.But though the momentary effort is reduced, since you are raising a mass against the gravity, the total energy consumed will be the same.Assume a rope passing over one pulley which is fastened to the roof, then dropping down round another pulley, before being fastened to the roof again. So the rope forms in total an 'S', and between the lower pulley and the roof it forms an 'U' shape.Assume your target mass is fastened to a hook on the lower pulley. Draw this.As you pull on the free end of the rope, you will have to pull two lengths (metres or feet) of rope down for each length that your target mass rises.In the overall scheme of things, you'll have to put in the same amount of work needed to raise your target mass to the roof. But the momentary effort will be halved. And you'll have moved twice as much rope as the distance your target mass rises. You have a 'mechanical advantage' of two times.____________________________________A single pulley, or two pulleys, does not magnify force, but does change the direction of the force. Three or more pulleys properly arranged (for example, in a block and tackle arrangement) can not only change the direction of a force but also magnify the force. For example, using a block and tackle hoist will allow you to lift hundreds of pounds while exerting much less force. The trade-off is that you must exert the smaller force over a longer period, which evens things out.
What position should the gear shift lever be in when tightening?
To lift the rock using the least amount of effort force,should push on the position farthest away from the fulcrum. This is position Z.
What is purpose of a pulley?
The purpose of a pulley is that it can lift heavier things at a quicker pace. Some examples of a pulley is a ski lift and alot of Roller Coasters have them also. I hope i have helped at least a little bit!!! (:

Pulley X
When do you use pulley?
1-To force change. 3-to move to change. 4-speed. 5-force 6 We high-speed we at least. 7-force at least.
Would a lever a pulley or inclined plane be least helpful in moving a heavy object?
none of them are the least helpful they all help things move upward except the lever but the most helpful one is the pulley a pulley takes up less space and it goes straight up so u can use less force

How do you estimate 15 from5?
You do not need to estimate. 5 - 15 = -10 and any estimation would require at least as much effort.
What does efficents mean?
functioning effectively and with the least waste of effort
Which type of pulley takes the least amount of work?
It would be more accurate to ask whuch pulley takes the least amount of FORCE. WORK=FORCE X DISTANCE so ultimately the amount of work will be the same depending on how far the load moves. If you are wondering which pully will be the easiest to use than you need to know something about pulleys. Each time a rope passes through a pulley, the amount of FORCE needed to move a load decreases. The more passes the greater the MECHANICAL ADVANTAGE. But, there is a trade off. You may not need to pull as hard, (less force) but you will have to pull more rope (greater distance) to move the load. So the total amount of work remains equal.
If you have a choice of what you are going to hit in a crash hit the object?
