A. Label the following parts of a fixed pulley

We are given a diagram of a fixed pulley system with five numbered labels to fill in.

Here’s what each number refers to:

1. Rope – This is the string or cable that runs over the pulley.
2. Load – The object being lifted (in this case, the bucket).
3. Pulley wheel – The circular wheel with a groove around its edge.
4. Axle – The central shaft or rod that holds the pulley wheel and allows it to rotate.
5. Groove – The curved channel on the edge of the pulley wheel where the rope sits.

✔ So, the correct labels are:

- 1: Rope
- 2: Load
- 3: Pulley wheel
- 4: Axle
- 5: Groove

B. Fill in the blanks with the correct answers

We are given a list of words:
turn, move upwards, load, simplifies, groove

And we need to complete the sentences:

> What will happen when the rope is pulled?

1. The groove at the wheel will
2. turn.
3. The load connected to the rope will
4. move upwards.
5. The fixed pulley simplifies the work to lift the load.

✔ Final filled-in sentences:

1. The groove at the wheel will
2. turn.
3. The load connected to the rope will
4. move upwards.
5. The fixed pulley simplifies the work to lift the load.

🔍 Explanation

- A fixed pulley is attached to a stationary point (like the ceiling). It changes the direction of the force but does not reduce the effort needed.
- When you pull down on the rope, the pulley wheel turns, and the load moves upward.
- The groove in the pulley helps keep the rope in place.
- Although it doesn’t make lifting easier in terms of force, it simplifies the task by allowing you to pull downward instead of lifting upward.
