that the movable pulley is not easy to help in carrying heavy things
Depends what the input force is and the mechanical advantage of the pulley system If effort force (input force) is 20 pounds in a 6 pulley system (3 fixed,3 movable) then load force (output force) is 120 pounds As 6 times 20 equals 120 pounds
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.

Force and Resistance
Using a movable pulley is known as using it to 'advantage'. The line going to the movable pulley contributes towards the force acting on the load. A line going to a fixed pulley, only serves to change the direction of the force.

Force and Resistance
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.
True
Yes. The IMA of a movable pulley is 2.
Using a movable pulley is known as using it to 'advantage'. The line going to the movable pulley contributes towards the force acting on the load. A line going to a fixed pulley, only serves to change the direction of the force.
It would take 150 kg to lift the load.
