Read the giver statements and select the correct option
Statement 1: Lift, escalator and crane all use pulleys to function.
Statement 2: A pulley is a rigid rod arranged in such a manner that it can move freely around a fixed point.

Options

A. Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B. Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C. Statement is true but statement 2 is false.
D. Both statements 1 and 2 are false.

Answer

To solve the question, we will analyze both statements one by one and determine their correctness.

**Step 1: Analyze Statement 1**
- Statement 1 claims: "Lift, escalator, and crane all use pulleys to function."
- Lifts, escalators, and cranes indeed use pulleys as part of their mechanisms to lift and lower loads.
- Therefore, Statement 1 is **True**.

**Step 2: Analyze Statement 2**
- Statement 2 claims: "A pulley is a rigid rod arranged in such a manner that it can move freely around a fixed point."
- A pulley is actually a wheel with a groove around its edge, designed to change the direction of a force applied to a rope or cable. It is not a rigid rod; rather, it is a circular object that rotates around a fixed point (the axle).
- Hence, Statement 2 is **False**.

**Step 3: Conclusion**
- Since Statement 1 is true and Statement 2 is false, the correct option is that Statement 1 is correct and Statement 2 is incorrect.

**Final Answer: Statement 1 is True, Statement 2 is False.**
