In a village well, a single fixed pulley is mounted on an iron beam to pull up water buckets. What is the primary operational advantage of using this fixed pulley?
It reduces the force needed to lift the water bucket by half.
It changes the direction of force, making it easier to pull downwards with body weight.
It speeds up the bucket without needing any effort.
It converts the linear motion into rotational motion of water.
Solution
A single fixed pulley does not reduce the required effort force (MA = 1), but it changes the direction of force so one can pull downward using body weight against gravity.
