Question

The simple machine with a grooved wheel and a rope is_______. (a pulley/wheel and axle).

Answer 1

1. A single fixed pulley is fixed on support and has a fixed axis of rotation.
2. It helps us to lift a load easily by changing the direction of the force.
3. With the help of the pulley arrangement, the effort is being applied at the other end of the string in the downward direction and this is accompanied by the weight of the person who is applying the effort to raise the load effectively.
4. The single fixed pulley does not decrease the effort but changes its direction for easy lifting of load.
5. The mechanical advantage of a single fixed pulley is 1.

Hence, the simple machine with a grooved wheel and a rope is a pulley.
