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.
