It would take 150 kg to lift the load.

The answer will depend on the distance that the 400 grams has to be moved.
1. The fixedpulley - requires more effort than the load. 2. The movable pulley - moves with the load which allows for less effort than load. 3. The combined pulley - effort is less than half the weight of the load
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.
Double pulley systems are different from the one pulley system because the weight is now attacked to a pulley instead of an anchor. Another pulley is used to take some of the weight. A two pulley system only requires half the effort as a single pulley system.

A double pulley system is simple. Instead of one wheel like the single pulley system has, the double pulley system has two wheels and carries more heavier loads than the single pulley system can hold.

Depending on the type of pulley system you have (Fixed/ movable/ combined pulley) using either of these will give you mechanical advantage. The different pulley types are designed to even the weight of the object your pulled out, this will enable you to lift heavier objects with a lighter pull

Yes, weight has a huge effect on a pulley system. The amount of weight being moved or lifted directly affects how well the pulley works, and too much weight can break it altogether. Weight is also the main leverage in a pulley system.
Movable pulley is attache to the object you are moving while Fixed Pulley changes direction of the applied force.LaDy_caRoLi "Christine carren alcantara"
