Let’s say that a man is able to lift from the floor a load of 100 kg. He is wanting to lift even more load. The man tied a rope to the load and passed the rope through a pulley block. The pulley is fixedly attached to the ceiling. How much weight should he be able to lift with the help of this pulley?

The man with a fixed pulley can lift no more than itself and even less. He can lift a load that does not exceed the weight of his body.
