Question

The single fixed pulley can also be regarded as a _______

Answer 1

1. The single fixed pulley is a modification of the class 1 lever.
2. A single fixed pulley is fixed on support and has a fixed axis of rotation.
3. It helps us to lift a load easily by changing the direction of the force.
4. With the help of the pulley arrangement, the effort is being applied at the other end of the string in the downward direction.
5. The effort is accompanied by the weight of the person who is applying the effort to raise the load effectively at the other end of the string.

Thus, the single fixed pulley does not decrease the effort required to move the load. It only changes the direction of effort.

Hence, the single fixed pulley can also be regarded as a class 1 lever.
