- When we use a pulley to lift heavy loads, it becomes easier because the pulley changes the direction in which we apply the force.
- This means we can pull down to lift something up, making it simpler for us to lift heavy things like buckets of water from a well.
- So, using a pulley helps us by changing how we pull, making the work easier and faster!

The correct option is a.
Here's why:
How a Pulley Works:
- A pulley is a simple machine consisting of a wheel with a groove around its edge and a rope or cable that runs around the groove.
- The wheel and rope system allows for a change in the direction of the force applied to lift a load.
The Advantage:
- When you pull down on the rope, the pulley redirects that downward force upwards, helping to lift the load.
- This change in direction makes it easier to lift heavy objects, especially when you're working against gravity.
Why Other Options Are Incorrect:
- b) The load becomes lighter: The pulley doesn't reduce the actual weight of the load.
- c) The load becomes heavier: This would make lifting even harder, so it's not correct.
- d) The pulley stops working: A properly functioning pulley actually makes work easier, so this option is also incorrect.
In essence, a pulley acts as a force multiplier by changing the direction of the force, making it easier to lift heavy loads.

Understanding the Pulley System
Using a pulley simplifies the lifting of heavy loads by altering the direction of the applied force. This mechanical advantage allows us to lift objects more easily. Let's break down how this works.
How a Pulley Helps
- Direction Change: When you pull down on the rope of a pulley, the load moves up. This change in direction allows you to use your body weight and gravity to assist in lifting.
- Force Advantage: If you were to lift the load directly, you would need to exert a force equal to the weight of the load. With a pulley, you can pull down with less effort, making it feel lighter.
Benefits of Using a Pulley
- Increased Control: By changing the direction of the force, you can control the load more effectively, preventing it from slipping or falling.
- Reduced Effort: Although the load's weight remains the same, the effort required to lift it is significantly decreased. This is especially helpful for heavy or bulky items.
Conclusion
In summary, the primary reason a pulley makes it easier to lift heavy loads is due to the change in the direction of the force. This allows for greater efficiency and control, making heavy lifting more manageable.
