How can you increase Mechanical Advantage of Pulley Up to 30 or more using less than 11 pulleys?

connect the rope/line to a fixed axle and have a large lever turning this. Distance traveled by effort will be greatly increased. Your pulley system is most likely over 50% efficient so your load will overhaul unless a brake is used to keep the line from running backwards

Why does a fixed pulley have a mechanical advantage of one and a movable pulley has a mechanical advantage of two?
we find mechanical advantage of pulley by using principle of lever. according to this moment of effort is equal to moment of moment of load. As in this case effort arm is equal to load arm. so mechanical advantage is equal to one. but we know we can never finish friction between rope used and pulley so mechanical advantage is less than one
Type of pulley that has additional numbers of ropes that help to increase mechanical advantage?
Fixed Pulley!!
What is the mechanical advantage of a stationary pulley?
Its 1 you need more than 1 to improve mechanical advantage i think it's 2 A single pulley means one axel, making the IMA = 1. A double pulley's IMA would = 2, and so on and so forth.
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 would happen to a pulley system if the load were increased?
Ideal mechanical advantage is the mechanical advantage when there is no friction. It is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load. But actual mechanical advantage will be less than this ideal mechanical advantage due to friction. In other words the efficiency will be less than 100 %. If the efficiency is 80%, it implies 20% is wasted due to friction while lifting a load. If we increase the load the friction also increases and hence the efficiency will decrease with the load.
What is the advantage of adding pulleys to a pulley system?
More mechanical advantage.
What is the mechanical advantage of systems of pulleys?
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
What is equal to the ideal mechanical advantage of a pulley system?
The ideal mechanical advantage of a pulley system is two times the number of pulleys in the system. This is the amount of force required to get the system moving.
a pulley system uses a 250-N force to lift a 2,740-N crate, What is the mechanical advantage of the system?
Answer: Mechanical advantage can be achieved just by adding more loops or pulleys. It is given that to lift a crate, a pulley system exerts a force of 2,740 newtons. It is required to find the mechanical advantage of the pulley system if the input force is 250 newtons What is the mechanical advantage of the pulley system if the exerted force changes from 2,740 newtons to 250 newtons? As if the force does some work, it increases the distance. Mechanical advantage does nothing with the number of pulleys. It only depends on the weight that is to be lift. Also, F1/F2 = 2740/250 = 10.96 The multiple pulleys create mechanical advantage. It can be achieved just by adding more loops or pulleys. Therefore, Mechanical advantage can be achieved just by adding more loops or pulleys.
What tools increase mechanical advantage?
A pulley or pliers
How can you increase the mechanical advantage of a pulley?
Increase the distance on the machine. :) XD

Which is better a incline plane or pulley?
A single pulley simply changes the direction of the force. A block and tackle or multiple pulleys can offer a mechanical advantage - same as an inclined plane. For the same mechanical advantage, a pulley system may be better because of lower friction.
The type of pully that does not have a mechanical advantage is?
The simple pulley is the type of pulley that does not have a mechanical advantage.
What is the mechanical advantage of the pulley system?
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
