The answer will depend on the distance that the 400 grams has to be moved.
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.
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.
With a movable pulley system, you would need to exert an effort force equal to half the weight being lifted. In this case, to lift a 300kg weight, you would need to apply an effort force of 150kg. This is because movable pulleys provide a mechanical advantage of 2, reducing the amount of effort force needed.
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.
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.

To calculate the effort force in a pulley system, start by counting the number of supporting ropes that are directly attached to the movable pulley. Divide the total weight being lifted by this number to find the effort force needed to lift the weight. This assumes an ideal pulley system with no friction or other resistive forces.
A movable pulley reduces the input force needed to lift weights by distributing the weight between two strands of rope. As the pulley moves up, the weight on one side is balanced by the force exerted on the other side, effectively halving the force needed to lift the weight. This mechanical advantage makes it easier to lift heavy objects.
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.
It would take 150 kg to lift the load.
In a movable pulley system, the effort force required would be equal to half the weight being lifted. So to lift a 300 kg weight, you would need to apply an effort force of 150 kg (approximately 1471 Newtons) assuming ideal conditions and neglecting friction and other losses.
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.
Oh, dude, the most effective pulley is the compound pulley system. It's like the rock star of pulleys, combining fixed and movable pulleys to give you some serious mechanical advantage. So, if you're looking to lift heavy stuff with minimal effort, that's the one you wanna go for.
