What is the importance of pulley?
pulleys allow you to lift significantly more weight than without them
Would a screw with more or less threads make work easier?
It is easier. The question is not complete enough to be answered. The word EASIER needs to be further defined. so the question should read: What is easier to [add information here]; more screw threads or less screw threads?
How much money does a system mechanic make?
A System Mechanics salary range depends on their location and what they are specifically servicing. For example, in Clayton, MO, a Building System Mechanic makes $46,000 on average, whereas in Portland, OR, an Aircraft Ordinance System Mechanic averages $56,000.
What are the advantages of a rotary system vs. other conventional systems?
The rotary system is more accurate. You can use the conventional system but I recommend the rotary.
State two reasons why helical gears are more favourable in a vehicle transmission than straight-cut spur gears?
Far more driving surface contact and easier gear selection.
What is double pulley system?
A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.

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)
When moving things off of the ground onto a higher surface is a pulley more effective or a catapult?
A catapult is probably more effective, though a pulley is easier and safer to use.
What is a double movable pulley?
A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.
What is the advantage of adding pulleys to a pulley system?
More mechanical advantage.
How much effort is needed to lift a 75 N weight using the pulley system?
If you are talking about a simple pulley with the pulley attached and load rope attached to the object then you will need a little more than 75N of force. Lifting an object (at a constant velocity) requires a force equal but opposite the weight of the object. With any simple machine you will need to do more work to overcome friction. If you were to use a single pulley with the pulley attached to the object then you will need a little more than 37.5 N. If you were to use a multiple pulley system then you would need to know the mechanical advantage of the pulley system.
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
More information of uses of pulley?
Pulley systems are used in the real world to lift large masses onto tall heights. You might have seen the workers repairing the roof of a house and using the pulley system to lift their tools or materials to the roof. A pulley is an example of a simple machine.The pulley system consists of one or more pulleys and a rope or a cable. The number of pulleys used may increase or decrease the mechanical advantage of the system. Generally, the higher the mechanical advantage is, the easier it is to lift the object that is being lifted.Overall, no matter how easy it is to use the pulley system, the system itself is not very efficient due to the force of friction. For example, one has to pull two meters of rope of cable through the pulleys in order to lift an object one meter.The applet below illustrates just that. Select the number of pulleys and drag the mouse to see the inefficiency of the system.
What do pulleys do to the direction of a force?
If you have a pulley, it will make lifting an object up easier. since it is easier for someone to pull something down then pick up, a pulley is made to pull the object up, in a way where you only have to pull down. (Because that's easier) for example, if your friend tries to life you off the ground, that is a lot harder. but, if you put a rope over a branch, hold on to one end, and have your friend pull the rope down or away from you, which will raise you up, it is a lot easier, and more convenient
