Question

Assertion (A): If the displacement of load is equal to the displacement of effort, then velocity ratio of such machine is 1.

Reason (R): Such a machine generally changes the direction of effort.

पर्याय

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion.

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correction explanation of Assertion.

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion.

Explanation:

The velocity ratio is exactly 1 because the effort and the load always move the same distance.

A single fixed pulley is used to change the direction of force, but that does not change the fact that the effort distance and load distance remain equal.
