What is the advantage of a moveable pulley?
A moveable pulley reduces the amount of force needed to lift an object by distributing the load between two sections of the rope. This type of pulley system also allows for the direction of the lifting force to be changed, making it easier to lift heavy objects vertically.
What are the three kinds of pulley?
The three types of pulleys are fixed pulley, movable pulley, and compound pulley. Fixed pulleys are attached to a stationary object, movable pulleys move along with the load, and compound pulleys combine both fixed and movable pulleys to provide mechanical advantage.
What is the mechanical advantage of each pulley system?
A single fixed pulley has a mechanical advantage of 1, as it only changes the direction of the force. A moveable pulley system has a mechanical advantage of 2, as it reduces the force required by half. A block and tackle system, which combines fixed and moveable pulleys, can have a mechanical advantage greater than 2, depending on the number of pulleys used.
What class lever is a pulley?
A pulley is a class 1 lever because the fulcrum (pivot point) is between the load (object being lifted) and the effort (force applied to lift the load).
What is the IMA of a pulley system?
The Ideal Mechanical Advantage (IMA) of a pulley system is equal to the number of sections of rope supporting the load. In a simple pulley system with one pulley, the IMA is 1. If multiple pulleys are used in a system, the IMA is calculated by counting the number of strands supporting the load.

What are two types of pulleys?
There are two basic types of pulleys. When the grooved wheel is attached to a surface it forms a fixed pulley. The main benefit of a fixed pulley is that it changes the direction of the required force. Another type of pulley, called a movable pulley, consists of a rope attached to some surface. The wheel directly supports the load, and the effort comes from the same direction as the rope attachment.

What is the IMA of a single fixed pulley?
Nothing, really. A slight loss due to friction. If the pulley is fixed to the load, then there is a 2:1 advantage.
What is the ideal mechanical advantage of a fixed pulley raising a 1 kg can of paint a distance of 10 m?
The mechanical advantage doesn't depend on the distance the load moves, any more than it depends on the color of the paint in the can. If the pulley is hanging from the ceiling and you pull down, then the ideal MA is 1 . If the rope is fixed to the ceiling, the pulley rides on it, and the load is hanging from the pulley, then the ideal MA is 2 .
What is the formula for the MA of a pulley?
The mechanical advantage (MA) of a pulley system is calculated using the formula: MA = Load Force / Effort Force. For a simple pulley, the MA is typically 1, as the effort needed to lift the load is equal to the load itself. However, in systems with multiple pulleys (block and tackle), the MA can equal the number of rope segments supporting the load. Thus, the more pulleys used, the greater the mechanical advantage.
Ma of a pulley?
The mechanical advantage (MA) of a pulley system is calculated by counting the number of ropes supporting the moving block or load. For a single fixed pulley, the MA is 1 as it changes the direction of the force but does not provide any mechanical advantage. For a system with multiple pulleys, the MA is equal to the number of ropes supporting the load.
What is the mechanical advantage of the pulley system?
The mechanical advantage of a pulley system is the ratio of the output force to the input force. It is calculated by dividing the load force by the effort force required to lift the load. The mechanical advantage of a pulley system can be greater than 1, making it easier to lift heavy objects.
A 9.4kg mass is attached to a light cord that passes over a massless frictionless pulley. The other end of the cord is attached to a 3.2kg mass. Determine final speed after mass 1 falls 4.5m?
A 9.4kg mass is attached to a light cord that passes over a massless frictionless pulley. The other end of the cord is attached to a 3.2kg mass. The final speed after mass 1 falls 4.5m is approximately 6.6 meter per square second.
