Question

Statement (1): In a quick return motion mechanism, Coriolis acceleration exists.

Statement (2): Two links in this mechanism oscillate with one sliding relative to the other
1. Both Statement I) and Statement II) are individually true and Statement II) is the correct explanation of Statement I)
2. Both Statement I) and Statement II) are individually true but Statement II) is not the correct explanation of Statement I)
3. Statement I) is true but Statement II) is false
4. Statement I) is false but Statement II) is true

Answer 1

Correct Answer - Option 3 : Statement I) is true but Statement II) is false

When a point on one link is sliding along another rotating link, such as in quick return motion mechanism, then the Coriolis component of the acceleration is to be calculated.

So, statement (1) is correct.

Whitworth quick return motion mechanism is an inversion of single slider crank chain. In this mechanism, one link rotates and other oscillates and slider (third link) will slides.

So, statement (2) is incorrect.
