According to Teach Engineering, a pulley system helps to perform work by switching directions of force and simplifying the movement of large objects. Different types of pulley systems include fixed, movable and multiple. More »

A double pulley system, also known as a block and tackle, provides a mechanical advantage that allows for increased lifting force to be applied when pulling a rope or cable. By dividing weight between multiple pulleys, h... More »

The pulley is an effective mechanism that allows the user to lift or drag an object without overexerting. Making a simple pulley system requires just a few basic steps. To construct this system, you will need a basic pul... More »

A pulley makes work easier by redirecting and amplifying force. It helps reverse the direction of an individual’s lifting force. As a user pulls a rope down, the pulley lifts the weight up. When two ropes and wheels are ... More »

A fixed pulley makes work easier by changing the direction of the force required to lift a load. To raise a load with a fixed pulley, a downward force is needed, which is easier than the upward force needed to lift the l... More »
