How does pulleys work?
Pulleys can multiply the force you apply. Example: I pull down on a pulley with TWO Pulleys THREE supporting Strands and the force is Multiplied by a factor of TWO, but you have to pull TWICE the length of Rope as the Distance the Object is Raised. Therefore you can LIFT more WEIGHT than you normally could.The relationship of Supporting Strands to the Force Multiplier is:(the number of Supporting Strands) - 1So a Pulley system with 5 Supporting Strands with Multiply YOUR input Force by 4 times. This type of System is referred to as "Block and Tackle".
What is input energy?
Where the energy enters the system.
How does a pulley change the input force?
A single pulley only changes the direction of the applied force. A second or more pulleys on the same rope will multiply the force applied by decreasing the distance of the applied force. This arrangement is called a block and tackle. Two pulleys double the force and halve the distance the force acts upon the mass. Three will triple the force while reducing the distance by 1/3, and so on. If 1 pound of force is applied to a rope with four pulleys on it over the distance of 10 feet of rope it will raise a 4 pound weight 2 1/2 feet.

When does output force equal input force?
Output force can only equal input force in a system where there are no losses. In the "real world" we live in, there are losses in every system, and that means that output force can nerver equal input force.
Can the number of pulleys affect the amount of force to lift a heavy objects to a high place?
Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.
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.

Contrast system input and system output?
There is a definite contrast between system input and system output. System input refers to raw data which is fed into the system while system output is processed data which is released by the system.
How does the negative feedbacks system work?
Some of the output is fed back to the input in such a way as to reduce change in the output.
What is relaxed system?
Is a system whose initial input and any previous input is 0.
How do you find the mechanical advantage of a simple machine?
To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
What is a constant input?
An input that does not change over time.
What is the significance of the bios?
The BIOS (Basic Input/Output System) is the built-in system of your motherboard. It allows the user to change motherboard settings and other various settings.
