1 . The difference between the three classes depends on where the force is, where the fulcrum is and where the load is. In a first class lever, the fulcrum is located between the input force and output force. In a second class lever, the output force is between the fulcrum and the input force.

2 . There are three types of levers: first class, second class and third class. The difference between the three classes depends on where the force is, where the fulcrum is and where the load is. In a first class lever, the fulcrum is located between the input force and output force.

3 . There are three types of levers: first class, second class and third class. The difference between the three classes depends on where the force is, where the fulcrum is and where the load is. In a first class lever, the fulcrum is located between the input force and output force.

4 . Fixed Pulley Systems - the pulley in such a type of system cannot change its place when the motion of rope or string takes place like in the case of the flagpole where the pulley cannot be moved up and down. Movable Pulley Systems - in this type of systems the pulley can be repositioned and move along the rope systems.
