Using the example above. If the load is lifted 2 metres, above the pulley wheel-the rope on the right hand side must be shortened by one metre and this also applies to the left hand side. Therefore, the effort can be seen to move twice as far as the load. A pulley system with the effort applied from above is very difficult to use. The most comfortable way to use a single moving pulley is combine it with a fixed pulley, seen below.
How do pulleys work? A fixed pulley, also known as a simple pulley, does not confer any mechanical advantage. The force needed to lift a load is equal to the downward force of gravity on the load. Using a moving pulley multiplies the lifting force by two, meaning that only half the force of gravity is needed to lift it.
