How does the minimum input change as you add more pulley to the system?
Adding more pulleys to a system reduces the amount of force required to lift an object. The more pulleys added, the greater the mechanical advantage, meaning the minimum input force needed to lift the object decreases. This is due to the increased number of support points distributing the weight of the object more evenly across the system.
What is a device that can multiply and change the direction of an input force?
A simple machine like a pulley can multiply and change the direction of an input force. By using multiple pulleys in a system, you can create a mechanical advantage that amplifies the force applied.
What is the input and output of pulleys?
The input of a pulley system is the force applied to the rope or belt, while the output is the resulting movement or lifting of the load. Pulleys are used to change the direction of the force applied, making it easier to lift heavy objects or move loads over a distance.
What is the practical use of a pulley that does not change the size of the input force?
A pulley that does not change the size of the input force can still be useful in redirecting the force's direction. This can be helpful in applications where you need to change the direction of the force to make it more convenient for a particular task or to maneuver around obstacles. Additionally, pulleys can be used to maintain tension in a system or to distribute the force evenly across multiple pulleys.
A pulley system always causes the direction of the output force to be the opposite of the input force true or false?
False. A pulley system can change the direction of the force applied, but it does not always result in the output force being in the opposite direction of the input force. The direction of the output force depends on the configuration of the pulleys in the system.

How do you Write a rule that relates the number of pulleys input force and output force?
To write a rule that relates the number of pulleys, input force, and output force, you can use the formula for mechanical advantage (MA) in a pulley system. The mechanical advantage is equal to the ratio of the output force (load) to the input force (effort): MA = Output Force / Input Force. In a pulley system, the mechanical advantage is also equal to the number of supporting ropes, which is determined by the number of pulleys used. Thus, you can express it as: Output Force = Input Force × Number of Pulleys.

How does a block and tackle multiply the input the force?
A block and tackle system multiplies the input force by using multiple pulleys. By distributing the load across several pulleys, the force needed to lift an object is reduced. Each additional pulley in the system adds more mechanical advantage, increasing the overall force multiplication.
What two ways can a machine alter an input force?
1. Take a small input and you get a large force.
Do pulleys systems change how much work you do?
Pulley systems do not change the amount of work done; they only change the direction or magnitude of the force applied. In an ideal pulley system, the work input is equal to the work output, neglecting friction and other losses. The mechanical advantage gained from a pulley system allows the same amount of work to be done with less force or over a shorter distance.
Does a pulley system cause the direction of the output force to be opposite to the direction of the input force?
A pulley system may cause the direction of the output force to differ from that of the input force, but is not guaranteed to do so. In a simple example, a double pulley could easily result in input and output forces in parallel.
What does a Machine change a force?
A machine can change the direction, magnitude, or both of a force. By utilizing mechanisms such as levers, pulleys, and gears, machines can amplify or reduce the force input by the user to achieve a desired output.
What are the simple machines in a linkage?
In a linkage, the simple machines typically include levers, pulleys, and gears. A lever amplifies force or changes the direction of motion, while pulleys can lift loads more easily by reducing the required input force. Gears transmit torque and can change the speed or direction of movement. Together, these simple machines work in conjunction to perform complex tasks in a mechanical system.
