How much effort is exerted if the weight is 400 grams and the pulley used is a movable pulley?
For a movable pulley, the effort required would be half of the weight being lifted. So with a weight of 400 grams, the effort exerted would be 200 grams. The movable pulley helps distribute the load, making it easier to lift the weight.
Why does a movable pulley have a mechanical advantage of 2?
A movable pulley has a mechanical advantage of 2 because it allows the effort force to be applied in a way that supports both the load and the weight of the pulley itself. When lifting a load with a movable pulley, the rope is effectively divided into two segments that bear the load's weight, which means you only need to exert half the force required to lift the load directly. This configuration reduces the input force needed to lift heavy objects, thereby providing a mechanical advantage of 2.

What is the function of a movable pulley?
A movable pulley changes the direction of the applied force, making it easier to lift heavy objects. As the pulley moves with the load, it reduces the amount of force needed to lift the object by distributing the weight between the two sections of the rope.
What is some information if I combine the fixed pulley and movable pulley?
Combining a fixed pulley and a movable pulley creates a block and tackle system, which increases mechanical advantage and allows for easier lifting of heavy loads. The fixed pulley changes the direction of the force applied, while the movable pulley reduces the amount of force needed to lift an object by distributing the weight across multiple segments of rope. This setup is widely used in various applications, such as construction and sailing, to enhance efficiency and reduce the effort required to lift heavy items.
In a movable pulley system where does the other effort come from?
In a movable pulley system, the other effort comes from the weight of the object being lifted. The movable pulley reduces the amount of force needed to lift the object by distributing the load between the pulling force and the weight of the object. As a result, the effort needed to lift the object is divided between the pulling force and the weight of the object itself.
Why the value of single movable pulley is 2?
A single movable pulley has a mechanical advantage of 2 because it reduces the effort needed to lift an object by half. This is due to the pulley system allowing the weight to be distributed between the weight being lifted and the tension in the supporting rope.
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.
How is a fixed pulley different from a movable pulley?
A fixed pulley is different from a movable pulley because a movable pulley has one end of the rope attached to it fixed on an unmoving object. The pulley is free to move with the rope. You pull the other end of the rope. Also, a movable pulley multiplies the applied force (effort force) and therefore has more mechanical advantage. A fixed pulley is attached to something that doesn't move, while one end of the rope is holding the weight, while the other is for pulling.A fixed pulley confers no mechanical advantage, but will convert motion in one direction into another direction.A movable pulley system, if the pulleys change their distance from each other, will confer a mechanical advantage.
How much effort force would you use to lift a 300 kg weight with a movable pulley system?
In a movable pulley system, the effort force required is half of the weight being lifted. So, to lift a 300 kg weight, you would need to apply an effort force equal to 150 kg.
Where can one find information on weight lifters?
There are information about weight lifting in books, magazines, and websites. Exercises and machines or weights to do weight lifting can be found at many stores. Before beginning any weight lifting be sure to talk to your doctor.
